As a developer, you focus on writing code for your application's functionality without having to worry about provisioning or managing servers. 3 | 4 | ## How Does it Work? 5 | In traditional computing, you typically rent or provision servers to run your applications. You have to manage these servers, ensuring they're properly configured, secured, and scaled to handle your application's workload. 6 | 7 | In serverless computing, you don't manage servers directly. Instead, you write functions - small pieces of code that perform specific tasks. These functions are then uploaded to a cloud provider's platform, such as AWS Lambda, Azure Functions, or Google Cloud Functions. 8 | 9 | When an event triggers your function (for example, an HTTP request, a file upload, or a database change), the cloud provider automatically spins up a container to execute your function. Once the function completes its task, the container is shut down. You're only charged for the resources used during the function's execution time, which makes serverless computing highly cost-effective, especially for sporadic workloads. 10 | 11 | ## Key Benefits of Serverless 12 | - Scalability: Serverless platforms automatically scale to handle incoming requests. You don't have to worry about configuring auto-scaling settings or provisioning additional servers during traffic spikes. 13 | 14 | - Cost-efficiency: Since you're only charged for the resources used during function execution, serverless computing can be more cost-effective compared to traditional server-based architectures, especially for applications with varying workloads. 15 | 16 | - Simplified Infrastructure Management: With serverless computing, you don't need to manage servers, operating systems, or runtime environments. This reduces the operational overhead for developers and allows them to focus more on writing code. 17 | 18 | - Faster Time-to-Market: Serverless platforms abstract away much of the infrastructure management complexity, allowing developers to quickly deploy and iterate on their applications. This can lead to faster development cycles and quicker time-to-market for new features. 19 | 20 | ## Use Cases 21 | - Web Applications: Serverless architectures are well-suited for building web applications, APIs, and microservices due to their ability to scale effortlessly and handle varying workloads. 22 | 23 | - Event-Driven Processing: Serverless functions excel in scenarios where you need to respond to events in near real-time, such as processing user uploads, handling IoT data streams, or reacting to changes in a database. 24 | 25 | - Batch Processing: Tasks like data processing, image resizing, or video transcoding can be efficiently handled using serverless functions, triggered by events like file uploads or scheduled tasks. 26 | 27 | ## Conclusion 28 | Serverless computing offers a paradigm shift in how developers build and deploy applications, abstracting away much of the underlying infrastructure complexity. By focusing on writing code and letting the cloud provider handle the rest, developers can build scalable, cost-effective, and agile applications more efficiently than ever before. 29 | -------------------------------------------------------------------------------- /Compliance/ISO 27001.md: -------------------------------------------------------------------------------- 1 | ISO 27001 is a widely recognized international standard that provides a framework for Information Security Management Systems (ISMS).

It's a way of ensuring the authenticity and integrity of digital information, such as documents or messages, in the online world. 5 | 6 | ## How Does it Work? 7 | 8 | - Key Pair: Imagine having two keys: a public key and a private key. The public key is shared with everyone, while the private key is kept secret. 9 | - Creating the Signature: When you want to sign a document or message, your private key is used to create a unique digital signature. This process involves complex mathematical algorithms that ensure the signature is practically impossible to forge. 10 | - Verification with Public Key: The digital signature is then attached to the digital information. Anyone who wants to verify the authenticity of the information can use your public key to check the signature. 11 | - Authenticity Check: If the signature matches with the information and can be decrypted using your public key, it confirms that the information hasn't been tampered with and that it indeed came from you. 12 | 13 | ## Why is it Important? 14 | 15 | - Authentication: Digital signatures provide a way to verify the identity of the sender. If a document carries a valid digital signature, you can trust that it comes from the claimed sender. 16 | - Integrity: Digital signatures ensure that the content of a document or message hasn't been altered since it was signed. If someone tries to modify the information, the signature won't match, indicating tampering. 17 | - Non-repudiation: With a digital signature, the sender cannot later deny their involvement. Once a digital signature is applied, it serves as evidence that the sender approved the content. 18 | - Secure Transactions: In the context of online transactions or sensitive communications, digital signatures enhance security by preventing unauthorized access and ensuring data integrity. 19 | 20 | ## Real-world Analogy: 21 | Think of it like sealing an envelope with a unique wax stamp.

It's a crucial component in securing online transactions, communications, and data. 24 | -------------------------------------------------------------------------------- /Cryptography/Encryption and Decryption.md: -------------------------------------------------------------------------------- 1 | # Encryption and Decryption 2 | ## Encryption 3 | Imagine you're sending a top-secret message to your friend, and you don't want anyone else to understand it if they happen to intercept it. This is where encryption comes in. Encryption is like putting your message in a secret code that only you and your friend can understand. 4 | 5 | In the digital world, this involves transforming your original message (plaintext) into an unreadable format (ciphertext) using a specific algorithm and a key. The algorithm is like a set of rules, and the key is the secret ingredient that makes the encryption unique. So, even if someone gets hold of the encrypted message, they won't be able to make sense of it without the key. 6 | 7 | There are different types of encryption algorithms, such as symmetric and asymmetric encryption: 8 | 9 | - Symmetric Encryption: In symmetric encryption, the same key is used for both encryption and decryption. It's like having a single key to lock and unlock a door. Both you and your friend need to have the same key to understand the message. 10 | 11 | - Asymmetric Encryption: Asymmetric encryption involves a pair of keys - a public key and a private key. The public key is used to encrypt the message, and the private key is used to decrypt it. It's like having a lock and key system where the lock (public key) is accessible to everyone, but only the owner has the unique key (private key) to open it. 12 | 13 | ## Decryption 14 | Now, let's talk about decryption, which is the process of turning the encrypted message back into its original form. It's like revealing the hidden meaning of the secret code. 15 | 16 | In symmetric encryption, the recipient uses the same key that was used for encryption to decrypt the message. In asymmetric encryption, the recipient uses their private key to decrypt the message that was encrypted with their public key. 17 | 18 | In summary, encryption is like putting your message in a secure envelope with a lock, and decryption is like using the right key to open that envelope and read the message. It's a crucial aspect of securing digital communication and information in today's interconnected world. 19 | -------------------------------------------------------------------------------- /Cryptography/Hashing.md: -------------------------------------------------------------------------------- 1 | # Hashing 2 | 3 | ## What is Hashing? 4 | 5 | Hashing is a process of converting input data (or a 'message') into a fixed-size string of characters, which is usually a sequence of numbers and letters. This output is commonly referred to as a "hash value" or simply a "hash." The idea is that no matter how large or small the input data is, the hash value always has a fixed length. 6 | 7 | ## Key Characteristics of Hashing: 8 | 9 | - Fixed Output Size: Hash functions produce a fixed-size output, regardless of the size of the input data. For example, whether you hash a single letter or an entire book, the resulting hash will have a predetermined length. 10 | - Deterministic: The same input will always produce the same hash value. If you hash a specific piece of data using a particular hash function, you'll get the same hash every time. 11 | - Irreversibility (One-way): Hash functions are designed to be one-way, meaning it should be computationally infeasible to reverse the process and obtain the original input data from its hash value. This property is crucial for security. 12 | - Collision Resistance: A good hash function minimizes the chance of two different inputs producing the same hash value. This is known as a collision. Collision resistance is vital to ensure the uniqueness of hash values. 13 | ## Common Use Cases of Hashing: 14 | 15 | - Data Integrity: Hashing is commonly used to verify the integrity of data. By comparing the hash value of original data with the hash value calculated after transferring or storing the data, one can determine if the data has been altered. 16 | - Password Storage: Instead of storing plain-text passwords, systems often store the hash of a password. During login, the entered password is hashed, and the hash is compared with the stored hash. This adds a layer of security as the actual password is not stored. 17 | - Digital Signatures: Hashing is an essential component in creating digital signatures. A hash of the message is signed with a private key, and the recipient can use the corresponding public key to verify both the authenticity of the sender and the integrity of the message. 18 | - Hash Tables: In computer science, hash functions are used in data structures like hash tables to quickly locate a data record given its search key. 19 | ## Examples of Hash Functions: 20 | 21 | - MD5 (Message Digest Algorithm 5): MD5 produces a 128-bit hash value and was widely used in the past. However, it is now considered insecure due to vulnerabilities. 22 | - SHA-256 (Secure Hash Algorithm 256-bit): Part of the SHA-2 family, SHA-256 produces a 256-bit hash and is commonly used for secure applications like blockchain. 23 | -bcrypt: bcrypt is a cryptographic hash function specifically designed for password hashing. It incorporates a salt (random data) and a cost factor to slow down hashing and make it more secure. 24 | 25 | In summary, hashing is a fundamental concept in computer science and cryptography, providing essential tools for ensuring data integrity, securing passwords, and enabling various applications across computing. 26 | -------------------------------------------------------------------------------- /Cryptography/Obfuscation.md: -------------------------------------------------------------------------------- 1 | # Obfuscation 2 | ## What is Obfuscation? 3 | 4 | Obfuscation is a technique used to make something unclear or difficult to understand. In the realm of computer science and programming, it specifically refers to making code (the instructions that tell a computer what to do) more challenging to comprehend. 5 | 6 | ## Why Use Obfuscation? 7 | 8 | The primary purpose of obfuscation in programming is to make the source code of a software application more difficult for humans to read and understand. This is done for various reasons, including: 9 | 10 | - Security: By obfuscating code, developers can make it harder for attackers to reverse engineer and understand the inner workings of a program. It can help protect sensitive information and algorithms from being easily discovered and exploited. 11 | - Intellectual Property Protection: Developers and companies invest a lot of time and resources in creating software. Obfuscation helps protect their intellectual property by making it challenging for others to copy or replicate their code. 12 | - License Enforcement: Obfuscation can be used to enforce licensing agreements by making it more difficult for users to tamper with or remove licensing checks from the code. 13 | - Reducing Code Size: In some cases, obfuscation is used to compress or reduce the size of the code, making it more efficient in terms of storage and transmission. 14 | 15 | ## How Does Obfuscation Work? 16 | 17 | Obfuscation techniques vary, but they often involve making code more convoluted without changing its functionality. Here are some common methods: 18 | 19 | - Variable and Function Renaming: Changing the names of variables and functions to meaningless or arbitrary identifiers makes it harder for someone reading the code to understand its purpose. 20 | - Code Encryption: Encrypting parts of the code so that the original instructions are not directly visible. During execution, the code is decrypted to its original form. 21 | - Control Flow Obfuscation: Altering the normal flow of the program by introducing extra or redundant code, making it difficult to follow the logical structure. 22 | - String Encryption: Encrypting strings (sequences of characters) in the code to hide sensitive information like API keys, URLs, or other hardcoded data. 23 | - Code Splitting and Code Splicing: Breaking the code into smaller parts and reorganizing them in a way that makes it harder to understand the overall logic. 24 | 25 | ## Challenges and Considerations 26 | 27 | - Debugging and Maintenance: Obfuscated code can be challenging to debug and maintain because the original intent of the code may not be immediately clear. 28 | - Performance Impact: Some obfuscation techniques can slightly impact the performance of the program, especially in terms of execution speed. 29 | - Legal and Ethical Considerations: While obfuscation can be a legitimate security measure, it's essential to consider legal and ethical implications, especially when dealing with open-source software or compliance with licensing agreements. 30 | 31 | In summary, obfuscation is a practice in programming to intentionally make code more confusing, mainly for security and protection purposes. It adds a layer of complexity, making it harder for unauthorized parties to understand and misuse the code. 32 | -------------------------------------------------------------------------------- /Cryptography/Public Key Infrastructure (PKI).md: -------------------------------------------------------------------------------- 1 | # Public Key Infrastructure (PKI) 2 | ## What is PKI? 3 | Public Key Infrastructure (PKI) is a set of technologies, processes, and standards that work together to secure communication and data. It's like a digital security system that helps ensure the confidentiality, integrity, and authenticity of information exchanged over networks, such as the internet. 4 | 5 | ## Key Concepts: 6 | - Public Key and Private Key: 7 | - In PKI, each user has a pair of cryptographic keys: a public key and a private key. 8 | - The public key is shared openly and is used to encrypt information. 9 | - The private key is kept secret and is used to decrypt the information encrypted with the corresponding public key. 10 | - Digital Certificates: 11 | - A digital certificate is like a digital ID card that verifies the ownership of a public key. 12 | - It contains information about the key owner, the public key itself, and is signed by a trusted third party known as a Certificate Authority (CA). 13 | - Certificate Authority (CA): 14 | - A CA is a trusted entity that issues digital certificates. It vouches for the association between a public key and an individual or entity. 15 | - Popular CAs include companies like VeriSign, DigiCert, and Let's Encrypt. 16 | - Registration Authority (RA): 17 | - The RA is responsible for verifying the identity of individuals or entities before a certificate is issued by the CA. 18 | - Digital Signature: 19 | - Digital signatures are like electronic fingerprints that ensure the authenticity and integrity of a message or document. 20 | - They are created using the private key and can be verified using the corresponding public key. 21 | 22 | ## How PKI Works: 23 | - Key Pair Generation: Users generate a pair of public and private keys. 24 | - Certificate Request: Users request a digital certificate from the CA, providing proof of identity to the RA. 25 | - Certificate Issuance: The CA verifies the user's identity and issues a digital certificate containing the public key. 26 | - Certificate Distribution: The digital certificate is distributed to the user, making it publicly available. 27 | - Digital Signatures and Encryption: Users can now use their private key to create digital signatures and decrypt messages encrypted with their public key. 28 | 29 | ## Use Cases: 30 | - Secure Communication: PKI secures communication by encrypting data, ensuring that only the intended recipient can decrypt and understand the information. 31 | - Digital Signatures: It provides a way to verify the authenticity of digital documents, assuring that they have not been tampered with. 32 | - Authentication: PKI helps in authenticating users and devices in online transactions and access control systems. 33 | 34 | In summary, PKI is a system that uses keys, certificates, and trusted authorities to establish a secure and reliable digital communication environment. It plays a crucial role in safeguarding sensitive information in the digital world. 35 | -------------------------------------------------------------------------------- /Cryptography/SSL Handshake.md: -------------------------------------------------------------------------------- 1 | # SSL Handshake 2 | The SSL handshake is a crucial process that occurs when two parties, typically a web browser and a server, establish a secure communication channel over the internet. SSL stands for Secure Socket Layer, and it has been succeeded by the more modern Transport Layer Security (TLS). However, for simplicity, I'll refer to it as SSL throughout this explanation. 3 | 4 | Here's a simplified breakdown of the SSL handshake: 5 | 6 | - Client Hello: 7 | - The process begins when a client (e.g., your web browser) initiates a connection to a server. The client sends a "Hello" message to the server, indicating that it wants to establish a secure connection. 8 | - This message includes information like the SSL/TLS version the client supports, supported cipher suites (encryption algorithms), and other parameters. 9 | 10 | - Server Hello: 11 | - The server responds with its own "Hello" message, selecting the highest SSL/TLS version that both the client and server support. 12 | - The server also chooses a cipher suite from the list provided by the client. The cipher suite includes encryption algorithms for securing the data transmission. 13 | - Key Exchange: 14 | 15 | - The server sends its public key to the client. The public key is a part of the server's SSL certificate, which also includes information about the server's identity. 16 | - The client verifies the server's SSL certificate to ensure it is valid, issued by a trusted Certificate Authority (CA), and belongs to the server it claims to represent. 17 | - Pre-master Secret: 18 | 19 | - The client generates a random pre-master secret and encrypts it with the server's public key. 20 | - This encrypted pre-master secret is then sent back to the server. 21 | - Session Key Derivation: 22 | 23 | - Both the client and server independently derive a session key from the pre-master secret and other parameters exchanged during the handshake. 24 | - This session key will be used for encrypting and decrypting the actual data exchanged during the secure session. 25 | - Finished: 26 | 27 | - The client sends a "Finished" message to the server to signal the completion of its part of the handshake. 28 | - The server also sends its "Finished" message to the client. 29 | 30 | At this point, the SSL handshake is complete, and a secure connection has been established. From this moment on, the client and server can exchange information securely, as the data will be encrypted using the derived session key. This encryption ensures confidentiality and integrity, preventing unauthorized parties from intercepting or tampering with the transmitted data. The SSL handshake is a fundamental process that underlies secure communication on the internet, providing a foundation for secure transactions, data exchange, and confidentiality. 31 | -------------------------------------------------------------------------------- /Cryptography/Salting.md: -------------------------------------------------------------------------------- 1 | # Salting 2 | ## What is Salting? 3 | 4 | Salting is a technique used to enhance the security of stored passwords by adding random data to the passwords before hashing them. This process helps protect against common attacks like rainbow table attacks and makes it more challenging for attackers to use precomputed tables of hashed passwords. 5 | 6 | ## Why is Salting Important? 7 | 8 | When a system stores passwords, it should never store them in plaintext due to the potential security risks. Instead, systems typically use a process called hashing, where the password is transformed into a fixed-length string of characters that looks random. However, this process has a weakness - if two users have the same password, their hashed passwords will also be the same. This is where salting comes in. 9 | 10 | ## How Does Salting Work? 11 | 12 | When a user creates an account or changes their password, a unique random value (the salt) is generated for that user. The salt is then combined with the password, and the result is hashed. The hashed password and the salt are stored in the system's database. 13 | 14 | For example, let's say a user chooses the password "password123" and a unique salt "a1b2c3d4" is generated for them. The system would store the hash of "password123a1b2c3d4" along with the salt "a1b2c3d4." 15 | 16 | ## Benefits of Salting: 17 | 18 | - Uniqueness: Each user has a unique salt, even if they have the same password. This prevents attackers from recognizing patterns and using precomputed tables effectively. 19 | 20 | - Security: Salting increases the complexity for attackers attempting to crack passwords. Even if they have a precomputed table for common passwords, they would need to generate a new table for each unique salt. 21 | 22 | - Randomness: The use of random salts ensures that even users with the same password will have different hash representations, adding an extra layer of unpredictability. 23 | 24 | - Protection Against Rainbow Tables: Rainbow tables are precomputed tables of hashed passwords. Salting makes these tables ineffective because each salt requires a separate table. 25 | 26 | ## Example of Salting in Code: 27 | In this example, the hash_password function takes a password and an optional salt. If no salt is provided, a random salt is generated using os.urandom(). The password and salt are then combined, and the hashlib.pbkdf2_hmac function is used to perform a secure hash. 28 | 29 | ```python 30 | import hashlib 31 | import os 32 | 33 | def hash_password(password, salt=None): 34 | if salt is None: 35 | salt = os.urandom(16) # Generate a random 16-byte salt 36 | 37 | # Combine the password and salt, then hash the result 38 | hashed_password = hashlib.pbkdf2_hmac('sha256', password.encode('utf-8'), salt, 100000) 39 | 40 | return hashed_password, salt 41 | 42 | # Example usage 43 | password = "password123" 44 | hashed_password, salt = hash_password(password) 45 | 46 | print(f"Password: {password}") 47 | print(f"Hashed Password: {hashed_password}") 48 | print(f"Salt: {salt}") 49 | 50 | ``` 51 | Salting is a crucial step in securing password storage and plays a significant role in protecting user accounts from various attacks. It adds complexity, randomness, and uniqueness to the hashed passwords, making it more challenging for attackers to compromise user accounts. 52 | -------------------------------------------------------------------------------- /Labs/Altoro Mutual.md: -------------------------------------------------------------------------------- 1 | Altoro Mutual is a fictional company often used as an example in cybersecurity training and demonstrations.

These rules ensure that different devices can communicate effectively with each other. Here, we'll explore some common protocols to help you understand their roles in networking. 3 | 4 | ## Transmission Control Protocol (TCP) 5 | 6 | - Purpose: TCP is a connection-oriented protocol that ensures reliable and ordered delivery of data between devices. 7 | - Characteristics: It establishes a connection before data transfer, breaks data into packets, numbers and sequences them, and ensures they are received correctly. 8 | ## Internet Protocol (IP) 9 | 10 | - Purpose: IP is responsible for addressing and routing packets of data so they can travel across networks and arrive at the correct destination. 11 | - Characteristics: There are two main versions, IPv4 and IPv6. IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses to accommodate the growing number of devices on the internet. 12 | ## Hypertext Transfer Protocol (HTTP) 13 | 14 | - Purpose: HTTP is the foundation of any data exchange on the web. It governs the communication between web browsers and servers. 15 | - Characteristics: It operates over TCP and is used for transmitting hypertext (text with links) and multimedia content. 16 | ## Hypertext Transfer Protocol Secure (HTTPS) 17 | 18 | - Purpose: Similar to HTTP, but with an added layer of security through encryption (SSL/TLS). It ensures that data exchanged between the user and the website remains confidential. 19 | ## File Transfer Protocol (FTP) 20 | 21 | - Purpose: FTP is used for transferring files between a client and a server on a network. 22 | - Characteristics: It allows for uploading and downloading files, and can operate in either active or passive mode. 23 | ## Simple Mail Transfer Protocol (SMTP) 24 | 25 | - Purpose: SMTP is used for sending emails. 26 | - Characteristics: It works with other protocols like POP3 or IMAP to deliver emails to the recipient's mailbox. 27 | ## Post Office Protocol version 3 (POP3) and Internet Message Access Protocol (IMAP) 28 | 29 | - Purpose: These protocols are used by email clients to retrieve messages from a mail server. 30 | - Characteristics: POP3 downloads emails to the local device, while IMAP allows users to view and manipulate emails on the server without downloading them. 31 | 32 | Understanding these common protocols is a foundational step in grasping how devices communicate over networks. As you delve deeper into networking, you'll encounter many more protocols, each serving specific purposes in the vast world of information exchange. 33 | -------------------------------------------------------------------------------- /Networking/IDS.md: -------------------------------------------------------------------------------- 1 | # What is an Intrusion Detection System (IDS)? 2 | An Intrusion Detection System (IDS) is like a digital security guard for your computer network. Its primary job is to watch over the data flowing through the network and identify any unusual or suspicious activities. Just as a security guard in a physical building would look out for signs of unauthorized entry, an IDS keeps an eye on your digital network for signs of potential cyber threats. 3 | 4 | ## Why do we need IDS? 5 | The internet is a vast and interconnected space where data travels between different devices and servers. Unfortunately, not everyone online has good intentions. Some individuals or programs may try to break into computer systems to steal information, cause damage, or disrupt normal operations. An IDS helps to detect and alert us about these malicious activities. 6 | 7 | ## How does IDS work? 8 | Think of IDS as a digital detective with a keen sense of observation. It uses two main approaches to identify potential threats: 9 | - Signature-Based Detection: 10 | - This method is similar to recognizing a known criminal's face. The IDS has a database of known attack patterns or "signatures." When it sees network traffic that matches these signatures, it raises an alarm. 11 | - For example, if the IDS knows what a common virus or hacking attempt looks like, it can spot those patterns and take action. 12 | - Anomaly-Based Detection: 13 | - Instead of looking for known "criminals," anomaly-based detection looks for unusual behavior. It learns what normal network activity looks like and flags anything that deviates significantly from the norm. 14 | - For instance, if your computer typically sends a small amount of data to a specific server, and suddenly there's a massive amount of data being sent elsewhere, the IDS might detect this anomaly. 15 | 16 | ## What happens when IDS detects something? 17 | When the IDS senses a potential threat, it doesn't intervene directly like a superhero. Instead, it alerts the network administrator or a security team. This notification allows them to investigate the situation, confirm if it's a real threat, and take appropriate action. 18 | 19 | 20 | An IDS is your digital security guard that tirelessly watches over your network, looking for any signs of trouble. It uses both known patterns and behavioral analysis to identify potential threats, helping you stay one step ahead of cybercriminals and ensuring the safety of your digital environment. 21 | -------------------------------------------------------------------------------- /Networking/IPS.md: -------------------------------------------------------------------------------- 1 | # What is an Intrusion Prevention System (IPS)? 2 | An Intrusion Prevention System (IPS) is like a superhero for your computer network. While an IDS (Intrusion Detection System) acts as a watchful eye, an IPS goes a step further by not only detecting potential threats but actively preventing them from causing harm. It's like having a security guard who not only spots intruders but also stops them in their tracks. 3 | 4 | ## Why do we need IPS? 5 | Just like in the physical world where we want to prevent burglars from entering our homes, in the digital world, we want to prevent malicious activities from compromising our computer systems. An IPS adds an extra layer of defense by proactively blocking or mitigating potential threats before they can do any damage. 6 | 7 | ## How does IPS work? 8 | Imagine your network as a fortress, and an IPS as a vigilant gatekeeper. Here's how it works: 9 | 10 | - Signature-Based Prevention: 11 | - Similar to the IDS, an IPS uses signatures to recognize known patterns of attacks. If it identifies a match between the incoming data and a known threat signature, it takes immediate action to block that data. 12 | - Think of this like having a list of known bad guys, and the IPS doesn't let them through the gate. 13 | - Anomaly-Based Prevention: 14 | - An IPS also pays attention to the usual behavior of your network. If it detects anything deviating significantly from the normal patterns, it can intervene. 15 | - For example, if suddenly there's a massive amount of data being sent from your computer, the IPS might see this as abnormal and prevent the excessive data flow. 16 | - Behavioral Analysis: 17 | - IPS monitors the behavior of network traffic, looking for signs of malicious activity based on how data is moving and interacting. If it spots something that seems suspicious or potentially harmful, it takes preventive action. 18 | - It's like having a guard who not only knows the faces of known troublemakers but also watches for any unusual behavior in the crowd. 19 | 20 | ## What happens when IPS detects something? 21 | When the IPS identifies a potential threat, it doesn't just raise an alarm; it takes action to block or neutralize the threat in real-time. This could involve blocking specific network traffic, isolating affected parts of the network, or even adapting its defenses based on the evolving nature of cyber threats. 22 | 23 | An IPS is your digital superhero, actively preventing cyber threats from infiltrating your network. By using both known signatures and behavioral analysis, it adds a crucial layer of defense, making sure that your digital fortress stays secure against potential intruders. 24 | -------------------------------------------------------------------------------- /Networking/Network Topologies.md: -------------------------------------------------------------------------------- 1 | # Network Topologies 2 | ## What is a Network Topology? 3 | 4 | A network topology is the way in which computers, printers, servers, and other devices are connected to form a network. It defines the physical or logical arrangement of these devices and the communication paths that connect them. 5 | 6 | 7 | ## Bus Topology 8 | 9 | Imagine a straight road, and all the houses along the road are connected to the same road. In a bus topology, all devices share a single communication line, which acts as the "road." 10 | It's simple but can lead to congestion if too many devices try to use the same line simultaneously. 11 | ## Ring Topology 12 | 13 | Think of a circular road where each house is connected to its adjacent houses, forming a ring. In a ring topology, each device is connected to exactly two other devices, forming a closed loop. 14 | Communication in a ring topology travels in one direction (clockwise or counterclockwise), passing through each device until it reaches the intended destination. 15 | ## Star Topology 16 | 17 | Picture a central hub (like the sun), and all other devices (like planets) are connected directly to the hub. In a star topology, all communication passes through the central hub. 18 | If one device wants to communicate with another, it sends the data to the hub, which then forwards it to the intended recipient. 19 | ## Mesh Topology 20 | 21 | Imagine a city with multiple interconnected roads, allowing different routes to reach any destination. Mesh topology is like that, where every device is connected to every other device. 22 | This provides redundancy and ensures that if one connection fails, there's always an alternative path for communication. 23 | ## Tree Topology 24 | 25 | Think of a tree with branches. In a tree topology, devices are arranged in a hierarchy, like the branches of a tree. It combines characteristics of star and bus topologies. 26 | The main advantage is the ability to expand the network easily by adding branches or leaves (devices). 27 | ## Hybrid Topology 28 | 29 | Sometimes, a network may use a combination of different topologies. This is known as a hybrid topology. For example, you might have a main star topology with each branch using a bus topology. 30 | 31 | The choice of network topology depends on various factors, including the size of the network, the type of tasks it needs to perform, and the cost. Each topology has its advantages and disadvantages, and the right one for a particular situation depends on the specific requirements and constraints. 32 | -------------------------------------------------------------------------------- /Networking/OSI Model.md: -------------------------------------------------------------------------------- 1 | # OSI Model 2 | The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers. This model helps in understanding how different networking protocols and technologies interact and communicate with each other. Each layer of the OSI model serves a specific purpose and communicates with the layers above and below it. 3 | 4 | Let's break down the seven layers of the OSI model from the bottom up: 5 | 6 | ## Physical Layer (Layer 1) 7 | 8 | The physical layer deals with the actual physical connection between devices. It defines the hardware elements such as cables, connectors, and the transmission of raw bits over a physical medium. Examples include Ethernet cables, fiber optics, and wireless transmission. 9 | ## Data Link Layer (Layer 2) 10 | 11 | This layer is responsible for creating a reliable link between two directly connected nodes. It involves the framing of data into frames, error detection, and correction. Ethernet and Wi-Fi operate at this layer, ensuring data integrity within a local network. 12 | ## Network Layer (Layer 3) 13 | 14 | The network layer is concerned with the logical addressing and routing of data between different networks. Internet Protocol (IP) is a key protocol at this layer, and routers operate at the network layer to determine the best path for data to travel across different networks. 15 | ## Transport Layer (Layer 4) 16 | 17 | The transport layer ensures end-to-end communication between devices. It is responsible for error detection, flow control, and retransmission of data if necessary. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are commonly used at this layer. 18 | ## Session Layer (Layer 5) 19 | 20 | The session layer manages sessions or connections between applications on different devices. It establishes, maintains, and terminates connections, allowing for dialogue control and synchronization between applications. This layer ensures that data is exchanged properly between applications. 21 | ## Presentation Layer (Layer 6) 22 | 23 | The presentation layer is responsible for translating data between the application layer and the lower layers. It deals with data formatting, encryption, and compression. It ensures that data is in a readable format for the application layer. 24 | ## Application Layer (Layer 7) 25 | 26 | The application layer is the topmost layer and is closest to the end-user. It provides network services directly to user applications. Examples include web browsers, email clients, and file transfer protocols. This layer interacts directly with software applications. 27 | 28 | Understanding the OSI model helps in troubleshooting network issues, designing networks, and developing interoperable networking protocols. Each layer has a specific role, and the model as a whole provides a systematic approach to understanding and implementing network communication. 29 | -------------------------------------------------------------------------------- /Networking/Types of Networks.md: -------------------------------------------------------------------------------- 1 | # Types of Networks 2 | 3 | Networks are essentially interconnected systems that allow communication and resource sharing among various devices. Here are some common types of networks: 4 | 5 | ## LAN (Local Area Network): 6 | 7 | - Definition: A Local Area Network is a network that covers a small geographic area, like a single building or a campus. 8 | - Example: Your home Wi-Fi network or the network within your school or office. 9 | ## WAN (Wide Area Network): 10 | 11 | - Definition: A Wide Area Network spans a larger geographic area and connects multiple LANs. It can cover cities, countries, or even continents. 12 | - Example: The internet itself is the largest WAN. It connects LANs from all around the world. 13 | ## MAN (Metropolitan Area Network): 14 | 15 | - Definition: A Metropolitan Area Network falls between LANs and WANs in terms of geographic coverage.

It plays a vital role in facilitating collaboration and information sharing within the cybersecurity community. 24 | -------------------------------------------------------------------------------- /Terminology/CVSS.md: -------------------------------------------------------------------------------- 1 | # Common Vulnerability Scoring System (CVSS) 2 | The Common Vulnerability Scoring System (CVSS) is a framework used to assess and communicate the severity of security vulnerabilities in software systems. It provides a standardized method for evaluating vulnerabilities, allowing security professionals to prioritize their response efforts effectively. CVSS scores help organizations understand the potential impact of a vulnerability and make informed decisions about how to mitigate it. 3 | 4 | ## Here's a breakdown of the key components of the CVSS 5 | 6 | - Base Score: The base score represents the intrinsic qualities of a vulnerability and is calculated using several metrics: 7 | 8 | - Attack Vector (AV): This metric describes how an attacker can exploit the vulnerability. For example, is physical access required, or can it be exploited remotely over a network? 9 | 10 | - Attack Complexity (AC): This metric considers how complex the attack is to execute. Is it straightforward or requires significant resources or conditions? 11 | 12 | - Privileges Required (PR): This metric indicates the level of privileges an attacker needs to exploit the vulnerability. Does the attacker require elevated privileges, or can it be exploited with minimal access? 13 | 14 | - User Interaction (UI): This metric assesses whether the vulnerability can be exploited without user interaction. Does the attacker need to trick the user into performing an action, or can it be exploited silently? 15 | 16 | - Scope (S): This metric determines whether the vulnerability impacts the system where it's located or can affect other systems. Is the vulnerability confined to the vulnerable component, or can it extend to other parts of the system? 17 | 18 | - Temporal Score: The temporal score reflects the characteristics of a vulnerability that may change over time. It includes metrics like exploit code maturity, remediation level, and report confidence. These factors can influence the urgency of patching or mitigating the vulnerability. 19 | 20 | - Environmental Score: The environmental score allows organizations to customize the CVSS score based on their specific deployment environment. Factors such as the importance of the affected asset, the sensitivity of the data it handles, and the security controls in place can all affect the overall risk posed by the vulnerability. 21 | 22 | The CVSS score is represented as a numeric value between 0.0 and 10.0, with higher scores indicating more severe vulnerabilities. Organizations can use these scores to prioritize their response efforts, focusing on vulnerabilities with the highest potential impact on their systems. 23 | 24 | It's important to note that while CVSS provides a valuable framework for assessing vulnerabilities, it's just one tool in the broader cybersecurity toolbox. Organizations should consider other factors, such as threat intelligence, asset criticality, and business impact, when making decisions about vulnerability management and remediation. 25 | 26 | 27 | 28 | 29 | -------------------------------------------------------------------------------- /Terminology/DMZ.md: -------------------------------------------------------------------------------- 1 | # What is a Demilitarized Zone (DMZ)? 2 | A Demilitarized Zone (DMZ) is a concept commonly used in the field of computer network security. It serves as a buffer zone between a private internal network and an external, untrusted network such as the internet. The primary purpose of a DMZ is to enhance the security of an organization's internal network by placing an additional layer of protection between the internal systems and potential external threats. 3 | 4 | ## Here's a simple analogy to help you understand 5 | 6 | Imagine a medieval castle. The innermost part of the castle is where the king, nobles, and important resources are kept – this is your internal network. The area surrounding the castle, but not directly inside, is a space where traders, messengers, and other non-residents can interact with the castle without getting too close to the important parts. This surrounding area is the Demilitarized Zone. 7 | 8 | Now, let's translate that analogy into network security terms: 9 | 10 | - Internal Network (Innermost Castle): This is where an organization's critical data, servers, and sensitive information are stored. It's the heart of the organization's digital infrastructure. 11 | - Demilitarized Zone (Surrounding Area): The DMZ is like a neutral ground that lies between the internal network and the external world, often represented by the internet. In the DMZ, you place servers and services that need to be accessed by external users, such as a website or email server. 12 | - External Network (Outside World): This is the wild, untrusted territory – the internet. It's full of potential threats like hackers, malware, and other security risks. 13 | 14 | By creating a DMZ, an organization can control and monitor traffic between the internal network and the external network. This ensures that only necessary and safe communication occurs between the internal and external environments. The DMZ acts as a protective barrier, preventing direct access to the sensitive internal network from the outside. 15 | 16 | In the context of computer networks, common components found in a DMZ include firewalls, intrusion detection/prevention systems, and proxy servers. These components work together to filter and monitor traffic, allowing the organization to balance the need for accessibility with the imperative of security. 17 | -------------------------------------------------------------------------------- /Terminology/Honeypots.md: -------------------------------------------------------------------------------- 1 | # What is a Honeypot ? 2 | A honeypot is a cybersecurity mechanism that is designed to attract and detect malicious activity on a computer network. Its primary purpose is to trick attackers into interacting with it, giving security professionals a chance to observe, analyze, and learn about their tactics, techniques, and procedures. 3 | 4 | Imagine you have a garden, and you want to protect it from intruders like rabbits or birds. One way to do this is by setting up a decoy, something that looks attractive to these creatures but is actually a trap. In the world of computer security, a honeypot is like a digital version of this decoy. 5 | 6 | 7 | ## Here are some key points to help you understand honeypots better: 8 | - Deception: Honeypots work by pretending to be vulnerable or valuable systems. They mimic the behavior of real systems or services to lure potential attackers. 9 | - Types of Honeypots: 10 | - Low-Interaction Honeypots: Simulate only the most basic behavior of a system or service. They are less risky but provide limited information. 11 | - High-Interaction Honeypots: Emulate real systems more closely, making them riskier but also more informative. Attackers interacting with high-interaction honeypots believe they are engaging with actual systems. 12 | - Goals of Honeypots: 13 | - Detection: Identify and track malicious activities, such as scanning for vulnerabilities or attempting unauthorized access. 14 | - Analysis: Learn about new attack methods and understand the tools and techniques used by potential intruders. 15 | - Prevention: Deter attackers by making them waste time and resources on a system that is designed to be a trap. 16 | - Deployment: 17 | - Honeypots can be deployed within an organization's internal network or placed on the internet to attract external threats. 18 | - They can be virtual or physical, depending on the specific needs and resources of the organization. 19 | - Challenges: 20 | - While honeypots are valuable tools, they require careful management to avoid becoming security risks themselves. 21 | - If not properly configured and monitored, honeypots can be used by attackers to launch further attacks or to gather intelligence about the organization. 22 | 23 | In essence, a honeypot is like a digital bait that cybersecurity professionals use to study and understand the tactics of potential attackers. It's an important tool in the world of cybersecurity, helping to enhance the overall security posture of organizations by providing valuable insights into the evolving landscape of cyber threats. 24 | -------------------------------------------------------------------------------- /Terminology/Jump Server.md: -------------------------------------------------------------------------------- 1 | # Jump Server 2 | A Jump Server, sometimes also referred to as a Jump Host or Jump Box, is a special-purpose computer on a network used to securely access and manage other devices, typically servers, within that network. It acts as an intermediary or gateway, allowing authorized users to connect to target systems without directly accessing them from outside the network. 3 | 4 | ## Here's a simplified explanation of how it works and why it's important 5 | 6 | - Secure Access Point: Imagine you have a house with multiple rooms, each containing valuable items. You don't want just anyone walking into those rooms and handling the items. So, you install a security door at the entrance, and only authorized personnel with the right keys can enter. 7 | 8 | - Authentication and Authorization: The Jump Server acts as that security door. When someone wants to access one of the servers inside the network, they first connect to the Jump Server. Here, they must authenticate themselves, proving they have the right credentials to enter. Once verified, they're granted access to the target system they need to manage. 9 | 10 | - Control and Monitoring: The Jump Server allows administrators to enforce security policies more effectively. They can monitor who accesses which servers, track activities, and ensure that only approved actions are performed. 11 | 12 | - Reduced Attack Surface: By funneling all remote access through a single point (the Jump Server), organizations can reduce the number of entry points into their network. This minimizes the risk of unauthorized access and makes it easier to implement and manage security measures. 13 | 14 | - Additional Security Measures: Advanced Jump Server setups often include additional security measures like multi-factor authentication, session recording, and encryption to further safeguard sensitive data and systems. 15 | 16 | - Compliance Requirements: Many industries have strict compliance regulations regarding access control and data security. Using a Jump Server can help organizations meet these requirements by providing a centralized and auditable access point. 17 | 18 | In summary, a Jump Server is like a checkpoint that ensures only authorized users can access critical systems within a network. It enhances security, simplifies management, and helps organizations comply with regulations, all while providing a more controlled and monitored environment for remote access. 19 | -------------------------------------------------------------------------------- /Terminology/MFA vs 2FA.md: -------------------------------------------------------------------------------- 1 | # MFA vs 2FA 2 | Let's break down MFA (Multi-Factor Authentication) and 2FA (Two-Factor Authentication) in a way that's easy to understand. 3 | 4 | ## Two-Factor Authentication (2FA) 5 | 6 | Imagine you have a treasure chest, and you want to keep it secure. You decide to use a lock as your first layer of defense. This lock requires a key to open, and only you have that key. This is like your username and password combination in the digital world. It's a single factor - something you know. 7 | 8 | But what if someone else gets hold of your key (password)? That's where Two-Factor Authentication (2FA) comes into play. In addition to the key (password), you add a second layer of protection. This second layer could be something you have, like a special code sent to your phone or email. So now, even if someone has your password, they still need that second piece to access your treasure chest. 9 | 10 | In simple terms, 2FA is like having two locks on your treasure chest - one that requires a key (password) and another that requires a unique code (something you have). 11 | 12 | ## Multi-Factor Authentication (MFA) 13 | 14 | Now, let's take the security of your treasure chest to the next level with Multi-Factor Authentication (MFA). Instead of just two layers, MFA involves adding multiple layers of protection. 15 | 16 | In addition to the lock and key (password) and the unique code (something you have), you might introduce a third layer. This could be something you are, like a fingerprint or a face scan. So, even if someone somehow manages to get your password and the unique code, they still need your fingerprint or face to unlock the chest. 17 | 18 | In summary, MFA is like fortifying your treasure chest with more than just two locks - it adds an extra layer, making it even more challenging for unauthorized individuals to gain access. 19 | 20 | To relate it back to the digital world, using MFA means combining different types of authentication methods (password, unique codes, biometrics) to enhance the security of your online accounts. It's like having a digital fortress with multiple barriers to keep your information safe. 21 | -------------------------------------------------------------------------------- /Terminology/NIST Cybersecurity Framework.md: -------------------------------------------------------------------------------- 1 | # NIST Cybersecurity Framework 2 | The NIST Cybersecurity Framework is like a guidebook or a set of instructions that helps organizations, big and small, protect themselves from cyber threats. NIST stands for the National Institute of Standards and Technology, which is a U.S. government agency that develops standards and guidelines to help various industries. 3 | 4 | Imagine you have a house that you want to keep safe from burglars. You'd probably do things like lock your doors, install security cameras, and maybe even get an alarm system. Well, the NIST Cybersecurity Framework is kind of like that, but for your digital information instead of your physical house. 5 | 6 | ## Here's how it works 7 | 8 | - Identify: First, you need to figure out what needs protecting. Just like you'd assess your house for vulnerable spots, you'll do the same for your digital systems and data. This step involves understanding what information you have, where it's located, and what could go wrong if it gets into the wrong hands. 9 | 10 | - Protect: Once you know what needs protecting, you put safeguards in place. This could mean using passwords, encryption, firewalls, and other security measures to keep your data safe. It's like installing locks and alarms on your doors and windows. 11 | 12 | - Detect: Despite your best efforts, sometimes bad things still happen. This step involves setting up systems to detect when something goes wrong, like if someone tries to break into your system or if there's a suspicious activity. It's like having security cameras that alert you when they see something unusual. 13 | 14 | - Respond: If you do detect a problem, you need to have a plan for dealing with it. This could involve things like shutting down compromised systems, fixing any damage, and notifying the appropriate authorities. It's like having a plan for what to do if your alarm goes off and you think someone is breaking into your house. 15 | 16 | - Recover: After a cyber incident, you need to get things back to normal as quickly as possible.

It's a technology used for enabling Single Sign-On (SSO), which allows users to access multiple applications or services with just one set of login credentials. 3 | 4 | ## How does it work? 5 | - Authentication: When you try to access a service or application that supports SAML SSO, you're redirected to an identity provider (IdP) for authentication. The IdP is typically a central system that manages user identities and credentials. 6 | - Identity Assertion: Once you're redirected to the IdP, you're prompted to log in using your username and password. After you successfully authenticate, the IdP generates a SAML assertion, which is like a digital certificate that contains information about your identity and authentication. 7 | - Assertion Delivery: The SAML assertion is then sent back to the service or application you were trying to access. This assertion serves as proof that you've been authenticated by the IdP. 8 | - Access Granted: The service or application receives the SAML assertion and validates it. If everything checks out, you're granted access without needing to log in again. This process all happens behind the scenes, so to you, it appears seamless – you're just logged in and ready to use the application. 9 | 10 | ## Why use SAML? 11 | - Convenience: SAML SSO eliminates the need for users to remember multiple sets of login credentials for different applications. With just one username and password, users can access all the services and applications they need. 12 | - Security: SAML employs strong authentication mechanisms and secure communication protocols, reducing the risk of unauthorized access and data breaches. 13 | - Centralized Control: SAML allows organizations to centrally manage user identities and access control policies from a single point, typically the IdP. This makes it easier to enforce security policies and ensure compliance with regulations. 14 | - Interoperability: SAML is a widely adopted standard supported by many applications and services, making it easy to integrate SSO functionality into existing systems. 15 | 16 | ## How is SAML different from other authentication methods? 17 | SAML differs from traditional username/password authentication in that it delegates the authentication process to a trusted third-party IdP. Instead of relying on each individual service or application to handle authentication, SAML centralizes authentication through the IdP, providing a more streamlined and secure authentication experience. 18 | 19 | SAML is a powerful technology for enabling Single Sign-On, simplifying user authentication, enhancing security, and providing centralized control over access to applications and services. By leveraging SAML, organizations can improve user experience, strengthen security, and streamline identity management processes. 20 | -------------------------------------------------------------------------------- /Terminology/SIEM.md: -------------------------------------------------------------------------------- 1 | # What is SIEM? 2 | 3 | SIEM stands for Security Information and Event Management.

In simpler terms, it's like having one key that unlocks multiple doors. 4 | 5 | ## How Does SSO Work? 6 | 7 | Imagine you have several accounts for different websites or applications—maybe one for email, one for social media, and one for your work. With traditional login methods, you'd need a separate set of credentials (username and password) for each. 8 | 9 | Now, enter SSO. When you use SSO, you log in once, and that login information is used to grant you access to multiple services without requiring you to log in again for each one. 10 | 11 | ## Key Components of SSO 12 | - Identity Provider (IDP): This is like the master key holder. The Identity Provider is where you initially log in. It could be a service like Google, Microsoft, or an organization's internal authentication system. 13 | - Service Provider (SP): These are the individual applications or services you want to access. They rely on the Identity Provider to confirm your identity. 14 | - User: That's you! The person using the system. 15 | 16 | ## Example Scenario: 17 | 18 | Let's say you use Google as your Identity Provider (IDP) and you want to access your email (Gmail) and a project management tool (like Asana) with SSO. 19 | 20 | - You visit Gmail and click the "Login with Google" button. 21 | - Instead of entering a separate Gmail username and password, Google's Identity Provider checks if you're already logged in. If yes, you're granted access to Gmail without needing to log in again. 22 | - Now, you decide to work on a project using Asana. You click "Login with Google" there too. 23 | - Asana's Service Provider talks to Google's Identity Provider, which confirms your identity. Since you're already logged in, you're seamlessly logged into Asana without having to enter another set of credentials. 24 | 25 | ## Benefits of SSO: 26 | - Convenience: You only need to remember one set of credentials, making life easier and reducing the risk of forgotten passwords. 27 | - Security: Since you're not managing multiple passwords, there's less chance of using weak or easily guessable passwords. Also, the centralized Identity Provider can enforce strong security measures. 28 | - Time-Saving: Logging in once and gaining access to multiple services saves time and reduces the frustration of repeated logins. 29 | 30 | In essence, Single Sign-On is like having a universal key that opens the doors to all your online destinations, making your digital life simpler and more secure. 31 | -------------------------------------------------------------------------------- /Threat modeling/PASTA.md: -------------------------------------------------------------------------------- 1 | # What is PASTA Threat Modeling? 2 | PASTA stands for Process for Attack Simulation and Threat Analysis.

This extra data can overflow into adjacent memory locations, potentially overwriting important data or code and leading to unpredictable behavior or security exploits. 3 | 4 | ## How Does Buffer Overflow Work? 5 | - Buffer: Programs often use buffers to store temporary data, such as user input or variables. 6 | 7 | - Input: When a program receives input that exceeds the size of the buffer allocated for it, the extra data can overwrite adjacent memory locations. 8 | 9 | - Memory Corruption: If the overflowed data reaches critical parts of memory, such as control data or function pointers, it can corrupt the program's execution flow. 10 | 11 | - Exploitation: Attackers can craft malicious input to trigger buffer overflows intentionally. By overwriting specific memory locations with their own code, they can hijack the program's execution, inject and execute malicious code, or crash the program. 12 | 13 | ## Example Scenario 14 | Imagine a program that reads user input into a buffer of fixed size. If a user enters more data than the buffer can hold, the excess data overflows into adjacent memory locations. 15 | 16 | For instance, if a buffer is designed to hold 10 characters and a user inputs 15 characters, the extra 5 characters overflow into adjacent memory regions, potentially corrupting critical program data or control structures. 17 | 18 | ## Impact of Buffer Overflow 19 | - Code Execution: Buffer overflow vulnerabilities can allow attackers to execute arbitrary code on the target system, potentially leading to unauthorized access, data theft, or system compromise. 20 | 21 | - Denial of Service: Buffer overflows can crash programs or cause system instability, leading to service interruptions or system downtime. 22 | 23 | - Security Exploits: Attackers can exploit buffer overflows to bypass security mechanisms, escalate privileges, or execute remote code execution attacks. 24 | 25 | ## Mitigating Buffer Overflow 26 | - Input Validation: Implement proper input validation to ensure that user input does not exceed the size of allocated buffers. 27 | 28 | - Bounds Checking: Use programming languages or libraries that perform bounds checking automatically to prevent buffer overflow vulnerabilities. 29 | 30 | - Secure Coding Practices: Follow secure coding practices, such as using safe string manipulation functions and avoiding unsafe memory operations. 31 | 32 | - Address Space Layout Randomization (ASLR): Employ ASLR techniques to randomize memory addresses, making it harder for attackers to predict memory locations for exploitation. 33 | 34 | ## Conclusion 35 | Buffer overflow vulnerabilities are significant security risks that can lead to code execution exploits and system compromise. By understanding how buffer overflows occur and implementing appropriate security measures such as input validation, bounds checking, and secure coding practices, developers can mitigate the risk of exploitation and protect their systems from malicious attacks. Regular security audits and updates are essential for maintaining a secure software environment. 36 | -------------------------------------------------------------------------------- /Vulnerabilities/CSRF.md: -------------------------------------------------------------------------------- 1 | # What is CSRF? 2 | CSRF, which stands for Cross-Site Request Forgery, is a type of security vulnerability that exploits the trust a website has in a user's browser. It allows an attacker to perform actions on behalf of a user without their knowledge or consent. 3 | 4 | ## How Does CSRF Work? 5 | - Authenticated User: The victim, usually an authenticated user, is tricked into visiting a malicious website or clicking on a specially crafted link. 6 | 7 | - Automatic Requests: The malicious website or link contains code that automatically sends forged requests to a different website where the victim is authenticated. These requests can perform actions such as changing account settings, making purchases, or transferring funds. 8 | 9 | - Trusted Session: Since the request originates from the victim's browser, the targeted website sees it as a legitimate request coming from the authenticated user. 10 | 11 | ## Example Scenario 12 | Let's say you're logged into your online banking account. While still logged in, you visit a malicious website, perhaps disguised as a harmless link shared on a forum. Unbeknownst to you, this website contains hidden code that automatically submits a request to transfer funds from your bank account to the attacker's account. 13 | 14 | ## Impact of CSRF 15 | - Unauthorized Transactions: Attackers can perform unauthorized actions on behalf of the victim, such as transferring funds, changing account settings, or deleting data. 16 | 17 | - Data Theft: CSRF attacks can lead to the theft of sensitive information stored on the targeted website. 18 | 19 | - Account Takeover: If the attacker gains control over the victim's account through CSRF, they can effectively take over the account and carry out malicious activities. 20 | 21 | ## Mitigating CSRF 22 | - CSRF Tokens: Include unique tokens in each request that are validated by the server to ensure the request originated from a legitimate source. 23 | 24 | - Same-Site Cookies: Set cookies to be sent only to the same origin, reducing the risk of CSRF attacks. 25 | 26 | - Referrer Policy: Configure servers to check the referrer header of incoming requests to ensure they originated from trusted sources. 27 | 28 | - Prompting User Action: Require users to confirm sensitive actions with additional authentication steps, such as entering a password or OTP. 29 | 30 | ## Conclusion 31 | CSRF attacks exploit the trust between a user's browser and a website they are logged into. By understanding how CSRF works and implementing appropriate security measures, such as CSRF tokens and same-site cookies, web developers can help protect against this type of vulnerability. Regular security audits and updates are essential to maintaining a secure web environment. 32 | -------------------------------------------------------------------------------- /Vulnerabilities/Clickjacking.md: -------------------------------------------------------------------------------- 1 | # What is Clickjacking? 2 | Clickjacking, also known as UI redressing, is a deceptive technique used by attackers to trick users into clicking on something different from what they perceive they are clicking on. It involves overlaying invisible or opaque elements over legitimate clickable elements on a webpage, thereby hijacking the user's clicks and potentially leading them to unintended actions. 3 | 4 | ## How Does Clickjacking Work? 5 | - Deceptive Interface: Attackers create a webpage with hidden or transparent layers containing malicious content, such as buttons or links. 6 | 7 | - Overlaying: The malicious content is overlaid on top of legitimate content that users would expect to interact with, such as buttons, forms, or links. 8 | 9 | - User Interaction: When users interact with the visible elements, they unknowingly trigger actions on the hidden or opaque layer, performing unintended actions. 10 | 11 | ## Example Scenario 12 | Suppose you visit a website that displays a familiar interface, such as a "Like" button for a social media post. However, unbeknownst to you, there's an invisible layer on top of the "Like" button that performs a different action, such as sharing the post to your profile without your consent. 13 | 14 | ## Impact of Clickjacking 15 | - Unauthorized Actions: Clickjacking can lead to users inadvertently performing actions they did not intend to, such as sharing content, making purchases, or revealing sensitive information. 16 | 17 | - Phishing Attacks: Attackers can use clickjacking to trick users into clicking on malicious links or buttons, leading to phishing attacks or the installation of malware. 18 | 19 | - Social Engineering: Clickjacking can be used as part of social engineering tactics to manipulate user behavior and deceive users into taking actions that benefit the attacker. 20 | 21 | ## Mitigating Clickjacking 22 | - Frame Busting: Implement frame-busting scripts that prevent your website from being loaded within an iframe on another domain, reducing the risk of clickjacking. 23 | 24 | - X-Frame-Options Header: Set the X-Frame-Options HTTP header to deny or limit framing of your webpages, preventing them from being embedded in iframes on other sites. 25 | 26 | - Content Security Policy (CSP): Utilize CSP headers to control which domains can embed your content in iframes, mitigating the risk of clickjacking attacks. 27 | 28 | - UI Design: Design user interfaces with clear visual cues and feedback to help users distinguish legitimate clickable elements from potentially malicious ones. 29 | 30 | ## Conclusion 31 | Clickjacking is a deceptive technique used by attackers to trick users into performing unintended actions on websites. By understanding how clickjacking works and implementing appropriate security measures such as frame busting, X-Frame-Options headers, and CSP policies, web developers can mitigate the risk of clickjacking attacks and protect users from malicious manipulation.

These entities can be used by attackers to disclose sensitive information, execute remote code, or perform other malicious actions. 3 | 4 | ## How Does XXE Work? 5 | - XML Input: The attacker sends specially crafted XML input to the vulnerable application. This input contains references to external entities, which are typically declared in the document type definition (DTD) section of the XML. 6 | 7 | - Entity Expansion: When the application processes the XML input, it expands these external entity references, fetching and including the content of the specified external resource. 8 | 9 | - Exploitation: Attackers can leverage this behavior to access sensitive files, interact with internal systems, or execute arbitrary code on the server. 10 | 11 | ## Example Scenario 12 | Let's consider a web application that allows users to upload XML files for processing. The application's code parses the XML input without proper validation. An attacker uploads an XML file containing a reference to an external entity that retrieves sensitive data, such as /etc/passwd, from the server's file system. When the application processes this XML file, it unwittingly discloses the contents of the /etc/passwd file to the attacker. 13 | 14 | ## Impact of XXE 15 | - Sensitive Data Exposure: Attackers can access sensitive files stored on the server, such as configuration files, user credentials, or system logs. 16 | 17 | - Server-Side Request Forgery (SSRF): XXE attacks can be combined with SSRF to interact with internal systems and services accessible to the server. 18 | 19 | - Denial of Service (DoS): XXE attacks can consume excessive server resources by causing recursive entity expansion, leading to denial of service. 20 | 21 | ## Mitigating XXE 22 | - Disable External Entity Processing: Configure XML parsers to disable the processing of external entities or limit their usage. 23 | 24 | - Input Validation: Implement strict input validation to filter out potentially malicious XML input, including DTD declarations and external entity references. 25 | 26 | - Use Safe XML Parsers: Utilize secure XML parsing libraries or frameworks that mitigate XXE vulnerabilities by default. 27 | 28 | - Content Security Policies: Implement content security policies to restrict the types of XML content that can be processed by the application. 29 | 30 | ## Conclusion 31 | XXE vulnerabilities pose significant risks to applications that process XML input without adequate safeguards. By understanding how XXE attacks work and implementing proper mitigation strategies, developers can protect their applications from exploitation and safeguard sensitive data. Regular security assessments and updates are crucial to maintaining a secure software environment. 32 | -------------------------------------------------------------------------------- /resource/cloudoneconformity.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/securitycipher/penetration-testing-roadmap/921abbda69f5bb605225cd0abb2b817771d33e7e/resource/cloudoneconformity.png -------------------------------------------------------------------------------- /resource/cloudsploit.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/securitycipher/penetration-testing-roadmap/921abbda69f5bb605225cd0abb2b817771d33e7e/resource/cloudsploit.png --------------------------------------------------------------------------------
