It 5 | can detect existing issues, known-insecure settings, existing strange behaviour, 6 | and options for further hardening. 7 | 8 | Recon can be used in existing systems to find out which elements can be improved 9 | and can provide some information about why the change is recommended. It can 10 | also be used to scan prepared system images to verify that they contain the 11 | expected protection. 12 | 13 | 14 | What can Recon help with 15 | ------------------------ 16 | 17 | Recon checks: 18 | 19 | - sysctl settings 20 | - application configs 21 | - security features used in compiled binaries 22 | - security features of current kernel 23 | - suspicious system conditions (like upgraded binaries which have not been 24 | restarted) 25 | - and many others 26 | 27 | Recon is most useful for verifying that the system security is configured as 28 | expected and for spotting hardening opportunities. 29 | 30 | 31 | What Recon isn't 32 | ---------------- 33 | 34 | System integrity checker - although it can be used to check the results or any 35 | such system. 36 | 37 | Rootkit detector - Recon uses only the most strightforward way to verify the 38 | system state. It does not try to detect existing hidden or malicious elements. 39 | 40 | Intrusion detection system - it will not attempt to detect active attackers. 41 | 42 | 43 | Recon usage 44 | ----------- 45 | 46 | Recon requires root privileges on the system to run most of its tests. All the 47 | system access is readonly however - no changes are made during the run and Recon 48 | should not affect processes on a production system. 49 | 50 | :: 51 | 52 | usage: reconbf [-h] [-c CONFIG_FILE] [-g {default,inline}] 53 | [-l--level {debug,info,error}] [-rf REPORT_FILE] 54 | [-rt {csv,json,html}] [-dm {all,fail,overall,notpass}] 55 | 56 | ReconBF - a Python OS security feature tester 57 | 58 | optional arguments: 59 | -h, --help show this help message and exit 60 | -c CONFIG_FILE, --config CONFIG_FILE 61 | use specified config file instead of default 62 | -g {default,inline}, --generate {default,inline} 63 | generates config file contetns with all the available 64 | modules listed and either configured to use the config 65 | that comes with the test, or inlines the current 66 | default configuration 67 | -l--level {debug,info,error} 68 | log level: can be "debug", "info", or "error" 69 | default=info 70 | -rf REPORT_FILE, --reportfile REPORT_FILE 71 | output file: default=result.out 72 | -rt {csv,json,html}, --reporttype {csv,json,html} 73 | output type: can be "csv", "json", or "html" 74 | -dm {all,fail,overall,notpass}, --displaymode {all,fail,overall,notpass} 75 | controls how tests are displayed: all-displays all 76 | results, fail-displays only tests which failed, 77 | overall-displays parent test statuses only, notpass- 78 | displays any test which didn't pass 79 | 80 | The default way to run Recon is just `python -m reconbf` or install it and run 81 | `reconbf` (both with `sudo` if running as a non-root user). 82 | 83 | If you need to adjust the configuration or verify your system against only a 84 | specific set of tests, you can generate a new configuration file using `-g 85 | inline` option. The resulting configuration will include all the available 86 | modules and also the default module configuration where needed. 87 | 88 | 89 | Interpreting results 90 | -------------------- 91 | 92 | Some tests will result in a very clear answer. For example `test_sysctl_values` 93 | is going to always give the real answer coming from the `sysctl` output. 94 | 95 | Other tests may not be that clear, or may be skipped when some system elements 96 | are not reachable. For example `test_ptrace_scope` depends on kernel config 97 | being available on the system and matching the currently deployed kernel. While 98 | this is the usual and expected state, any failures or skipped tests should be 99 | investigated separately and understood before taking actions to correct them. 100 | 101 | Other tests may rely on information which is not always available. For example 102 | `test_binaries` will attempt to check whether some binaries were compiled with 103 | stack protection. While this check will not have false-positives, it may report 104 | a false-negative if the analysed binary was compiled with `-fstack-protector` 105 | (not `-fstack-protector-all`) and gcc decides that none of the functions 106 | contained buffers that require protection. 107 | 108 | 109 | Module development 110 | ------------------ 111 | 112 | While developing new modules, please keep the following in mind: 113 | 114 | - ensure the code style matches (partially enforced by flake8 already) 115 | - new modules should come with unittests for them 116 | - new modules should not do direct IO operations; files or processes should be 117 | opened by either general abstractions in `reconbf.utils`, or local helpers in 118 | separate functions - this is to help writing small tests 119 | 120
