`--service-account PATH` - Path to service account JSON file 92 | - `--customer-id ID` - Chronicle instance ID 93 | - `--project-id ID` - GCP project ID 94 | - `--region REGION` - Chronicle API region (default: us) 95 | - `--output FORMAT` - Output format (json, text) 96 | - `--start-time TIME` - Start time in ISO format (YYYY-MM-DDTHH:MM:SSZ) 97 | - `--end-time TIME` - End time in ISO format (YYYY-MM-DDTHH:MM:SSZ) 98 | - `--time-window HOURS` - Time window in hours (alternative to start/end time) 99 | 100 | ## Commands 101 | 102 | ### Search UDM Events 103 | 104 | Search for events using UDM query syntax: 105 | 106 | ```bash 107 | secops search --query "metadata.event_type = \"NETWORK_CONNECTION\"" --max-events 10 108 | ``` 109 | 110 | Search using natural language: 111 | 112 | ```bash 113 | secops search --nl-query "show me failed login attempts" --time-window 24 114 | ``` 115 | 116 | Export search results as CSV: 117 | 118 | ```bash 119 | secops search --query "metadata.event_type = \"USER_LOGIN\" AND security_result.action = \"BLOCK\"" --fields "metadata.event_timestamp,principal.user.userid,principal.ip,security_result.summary" --time-window 24 --csv 120 | ``` 121 | 122 | > **Note:** Chronicle API uses snake_case for UDM field names. For example, use `security_result` instead of `securityResult`, `event_timestamp` instead of `eventTimestamp`. Valid UDM fields include: `metadata`, `principal`, `target`, `security_result`, `network`, etc. 123 | 124 | ### Get Statistics 125 | 126 | Run statistical analyses on your data: 127 | 128 | ```bash 129 | secops stats --query "metadata.event_type = \"NETWORK_CONNECTION\" 130 | match: 131 | target.hostname 132 | outcome: 133 | \$count = count(metadata.id) 134 | order: 135 | \$count desc" --time-window 24 136 | ``` 137 | 138 | ### Entity Information 139 | 140 | Get detailed information about entities like IPs, domains, or file hashes: 141 | 142 | ```bash 143 | secops entity --value "8.8.8.8" --time-window 24 144 | secops entity --value "example.com" --time-window 24 145 | secops entity --value "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855" --time-window 24 146 | ``` 147 | 148 | ### Indicators of Compromise (IoCs) 149 | 150 | List IoCs in your environment: 151 | 152 | ```bash 153 | secops iocs --time-window 24 --max-matches 50 154 | secops iocs --time-window 24 --prioritized --mandiant 155 | ``` 156 | 157 | ### Log Ingestion 158 | 159 | Ingest raw logs: 160 | 161 | ```bash 162 | secops log ingest --type "OKTA" --file "/path/to/okta_logs.json" 163 | secops log ingest --type "WINDOWS" --message "{\"event\": \"data\"}" 164 | ``` 165 | 166 | Add custom labels to your logs: 167 | ```bash 168 | # Using JSON format 169 | secops log ingest --type "OKTA" --file "/path/to/okta_logs.json" --labels '{"environment": "production", "source": "web-portal"}' 170 | 171 | # Using key=value pairs 172 | secops log ingest --type "WINDOWS" --file "/path/to/windows_logs.xml" --labels "environment=test,team=security,version=1.0" 173 | ``` 174 | 175 | Ingest UDM events: 176 | 177 | ```bash 178 | secops log ingest-udm --file "/path/to/udm_event.json" 179 | ``` 180 | 181 | List available log types: 182 | 183 | ```bash 184 | secops log types 185 | secops log types --search "windows" 186 | ``` 187 | 188 | ### Rule Management 189 | 190 | List detection rules: 191 | 192 | ```bash 193 | secops rule list 194 | ``` 195 | 196 | Get rule details: 197 | 198 | ```bash 199 | secops rule get --id "ru_12345" 200 | ``` 201 | 202 | Create a new rule: 203 | 204 | ```bash 205 | secops rule create --file "/path/to/rule.yaral" 206 | ``` 207 | 208 | Update an existing rule: 209 | 210 | ```bash 211 | secops rule update --id "ru_12345" --file "/path/to/updated_rule.yaral" 212 | ``` 213 | 214 | Enable or disable a rule: 215 | 216 | ```bash 217 | secops rule enable --id "ru_12345" --enabled true 218 | secops rule enable --id "ru_12345" --enabled false 219 | ``` 220 | 221 | Delete a rule: 222 | 223 | ```bash 224 | secops rule delete --id "ru_12345" 225 | secops rule delete --id "ru_12345" --force 226 | ``` 227 | 228 | Validate a rule: 229 | 230 | ```bash 231 | secops rule validate --file "/path/to/rule.yaral" 232 | ``` 233 | 234 | Search for rules using regex patterns: 235 | 236 | ```bash 237 | secops rule search --query "suspicious process" 238 | secops rule search --query "MITRE.*T1055" 239 | ``` 240 | 241 | ### Alert Management 242 | 243 | Get alerts: 244 | 245 | ```bash 246 | secops alert --time-window 24 --max-alerts 50 247 | secops alert --snapshot-query "feedback_summary.status != \"CLOSED\"" --time-window 24 248 | secops alert --baseline-query "detection.rule_name = \"My Rule\"" --time-window 24 249 | ``` 250 | 251 | ### Case Management 252 | 253 | Get case details: 254 | 255 | ```bash 256 | secops case --ids "case-123,case-456" 257 | ``` 258 | 259 | ### Data Export 260 | 261 | List available log types for export: 262 | 263 | ```bash 264 | secops export log-types --time-window 24 265 | secops export log-types --page-size 50 266 | ``` 267 | 268 | Create a data export: 269 | 270 | ```bash 271 | secops export create --gcs-bucket "projects/my-project/buckets/my-bucket" --log-type "WINDOWS" --time-window 24 272 | secops export create --gcs-bucket "projects/my-project/buckets/my-bucket" --all-logs --time-window 24 273 | ``` 274 | 275 | Check export status: 276 | 277 | ```bash 278 | secops export status --id "export-123" 279 | ``` 280 | 281 | Cancel an export: 282 | 283 | ```bash 284 | secops export cancel --id "export-123" 285 | ``` 286 | 287 | ### Gemini AI 288 | 289 | Query Gemini AI for security insights: 290 | 291 | ```bash 292 | secops gemini --query "What is Windows event ID 4625?" 293 | secops gemini --query "Write a rule to detect PowerShell downloading files" --raw 294 | secops gemini --query "Tell me about CVE-2021-44228" --conversation-id "conv-123" 295 | ``` 296 | 297 | Explicitly opt-in to Gemini: 298 | 299 | ```bash 300 | secops gemini --opt-in 301 | ``` 302 | 303 | ##

This guide explains how to configure proxy settings when using the SDK. 4 | 5 | ## Table of Contents 6 | - [Basic Proxy Configuration](#basic-proxy-configuration) 7 | - [Authentication Methods](#authentication-methods) 8 | - [Environment Variables](#environment-variables) 9 | - [Programmatic Configuration](#programmatic-configuration) 10 | - [SSL/TLS Certificates](#ssltls-certificates) 11 | - [Troubleshooting](#troubleshooting) 12 | 13 | ## Basic Proxy Configuration 14 | 15 | ### Environment Variables Method (Recommended) 16 | 17 | The simplest way to configure a proxy is through environment variables: 18 | 19 | ```bash 20 | # For HTTP traffic 21 | export HTTP_PROXY="http://proxy.example.com:3128" 22 | 23 | # For HTTPS traffic (most common for Chronicle API) 24 | export HTTPS_PROXY="http://proxy.example.com:3128" 25 | 26 | # Optional: Bypass proxy for specific hosts 27 | export NO_PROXY="localhost,127.0.0.1,.internal.domain" 28 | ``` 29 | 30 | Then use the SDK normally: 31 | ```python 32 | from secops import SecOpsClient 33 | 34 | # The client will automatically use the configured proxy 35 | client = SecOpsClient() 36 | chronicle = client.chronicle(region="us") 37 | ``` 38 | 39 | ### Programmatic Configuration 40 | 41 | You can also set proxy configuration in your code: 42 | 43 | ```python 44 | import os 45 | 46 | # Set proxy before initializing the SDK 47 | os.environ['HTTPS_PROXY'] = 'http://proxy.example.com:3128' 48 | os.environ['HTTP_PROXY'] = 'http://proxy.example.com:3128' 49 | 50 | from secops import SecOpsClient 51 | client = SecOpsClient() 52 | ``` 53 | 54 | ## Authentication 55 | 56 | ### Proxy Authentication 57 | 58 | If your proxy requires authentication: 59 | 60 | ```python 61 | import os 62 | 63 | # Format: protocol://username:password@host:port 64 | os.environ['HTTPS_PROXY'] = 'http://user:pass@proxy.example.com:3128' 65 | 66 | from secops import SecOpsClient 67 | client = SecOpsClient() 68 | ``` 69 | 70 | ### Google Authentication Through Proxy 71 | 72 | The proxy configuration works transparently with all SDK authentication methods: 73 | 74 | ```python 75 | import os 76 | 77 | # Set proxy 78 | os.environ['HTTPS_PROXY'] = 'http://proxy.example.com:3128' 79 | 80 | # 1. Application Default Credentials (ADC) 81 | client = SecOpsClient() # Uses ADC through proxy 82 | 83 | # 2. Service Account 84 | client = SecOpsClient(service_account_path="/path/to/service-account.json") # Uses proxy 85 | 86 | # 3. Explicit credentials 87 | client = SecOpsClient(credentials=your_credentials) # Uses proxy 88 | ``` 89 | 90 | ## SSL/TLS Configuration 91 | 92 | ### Custom Certificates 93 | 94 | If your proxy uses custom SSL certificates: 95 | 96 | ```python 97 | import os 98 | 99 | # Option 1: Specify CA certificate 100 | os.environ['REQUESTS_CA_BUNDLE'] = '/path/to/your/cert.pem' 101 | 102 | # Option 2: Specify CA certificate directory 103 | os.environ['REQUESTS_CA_PATH'] = '/path/to/your/certs/dir' 104 | ``` 105 | 106 | ### Self-signed Certificates (Not Recommended for Production) 107 | 108 | ```python 109 | import os 110 | import urllib3 111 | 112 | # Disable SSL verification warnings 113 | urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) 114 | 115 | # Set verify=False in your requests (NOT recommended for production) 116 | os.environ['PYTHONWARNINGS'] = 'ignore:Unverified HTTPS request' 117 | ``` 118 | 119 | ## Required Proxy Access 120 | 121 | Your proxy must allow access to these Google domains: 122 | 123 | - `*.googleapis.com` - API endpoints 124 | - `accounts.google.com` - Authentication 125 | - `oauth2.googleapis.com` - Token management 126 | 127 | ## Troubleshooting 128 | 129 | ### Common Issues 130 | 131 | 1. **Connection Errors** 132 | - Verify proxy URL and port are correct 133 | - Check if proxy requires authentication 134 | - Ensure proxy is accessible from your network 135 | - Verify required domains are allowlisted in proxy configuration 136 | 137 | 2. **SSL Certificate Errors** 138 | - Verify CA certificate path is correct 139 | - Ensure certificates are up to date 140 | - Check if proxy requires specific SSL configuration 141 | 142 | 3. **Authentication Issues** 143 | - Verify proxy credentials are correct 144 | - Check if proxy requires specific authentication headers 145 | - Ensure Google authentication endpoints are accessible 146 | 147 | ### Debug Logging 148 | 149 | Enable debug logging to troubleshoot proxy issues: 150 | 151 | ```python 152 | import logging 153 | 154 | # Enable debug logging for requests and urllib3 155 | logging.basicConfig(level=logging.DEBUG) 156 | logging.getLogger("urllib3").setLevel(logging.DEBUG) 157 | ``` 158 | 159 | ### Environment Variables Reference 160 | 161 | | Variable | Description | 162 | |----------|-------------| 163 | | `HTTP_PROXY` | Proxy for HTTP traffic | 164 | | `HTTPS_PROXY` | Proxy for HTTPS traffic | 165 | | `NO_PROXY` | Comma-separated list of hosts to exclude from proxying | 166 | | `REQUESTS_CA_BUNDLE` | Path to CA certificate bundle | 167 | | `REQUESTS_CA_PATH` | Path to directory containing CA certificates | 168 | 169 | ## Best Practices 170 | 171 | 1. Always set up proxies before initializing the SDK 172 | 2. Use environment variables for proxy configuration when possible 173 | 3. Ensure proper SSL certificate handling in production 174 | 4. Keep proxy access lists updated with required Google domains 175 | 5. Use secure HTTPS proxies in production environments 176 | 6. Implement proper error handling for proxy-related issues 177 | 178 | ## Example Implementation 179 | 180 | Here's a complete example showing proper proxy configuration: 181 | 182 | ```python 183 | import os 184 | import logging 185 | from secops import SecOpsClient 186 | from secops.exceptions import SecOpsError 187 | 188 | # Configure logging 189 | logging.basicConfig(level=logging.INFO) 190 | logger = logging.getLogger(__name__) 191 | 192 | # Configure proxy 193 | os.environ['HTTPS_PROXY'] = 'http://proxy.example.com:3128' 194 | os.environ['REQUESTS_CA_BUNDLE'] = '/path/to/cert.pem' 195 | 196 | try: 197 | # Initialize client 198 | client = SecOpsClient() 199 | 200 | # Initialize Chronicle 201 | chronicle = client.chronicle(region="us") 202 | 203 | # Test connection 204 | response = chronicle.list_rules() 205 | logger.info("Successfully connected through proxy") 206 | 207 | except SecOpsError as e: 208 | logger.error(f"Failed to connect: {e}") 209 | ``` 210 | 211 | -------------------------------------------------------------------------------- /examples/data_export_example.py: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env python3 2 | # Copyright 2025 Google LLC 3 | # 4 | # Licensed under the Apache License, Version 2.0 (the "License");
