Intercept：一套强大的代码静态分析审计策略
INTERCEPT是一套强大的代码静态分析审计策略，这套策略集简单易用，占用空间小，可以通过快速且强大的多行扫描工具来扫描你的代码库。除此之外，广大研究人员还可以将其作为数据采集器和检查器，或把它当作一款跨平台的武器化ripgrep来使用。
功能介绍
代码即策略；
细粒度正则策略；
多个执行级别；
静态分析，无守护进程；
低占用空间，可自我更新的二进制文件；
易于集成在任何CI/CD管道上；
声明式策略，以降低复杂性；
无自定义策略语言；
代码即策略
“代码即策略”的思想来源于策略的管理和自动化实现这方面，通过将策略以YAML文件代码的形式来呈现，是已经过验证的软件开发最佳实践，有助于研究人员实现版本控制、自动测试和自动部署。
工作机制
1、拦截和分析命令行接口代码； 2、YAML文件策略实施；
INTERCEPT会整合环境标记、YAML策略和可选参数来生成一个全局配置文件，它可以递归扫描目标路径以查找违反策略的代码，并生成人类可读的详细扫描及分析报告。
扫描报告输出样本：

# Standard package (intercept + ripgrep) for individual platforms -- core-intercept-rg-*.zip # Cross Platform Full package (intercept + ripgrep) -- x-intercept.zip # Build package to build on all platforms (Development) -- setup-buildpack.zip # Package of the latest compatible release of ripgrep (doesn't include intercept) -- i-ripgrep-*.zip
快速开始
首先，根据自己的平台下载最新版本的INTERCEPT：
--- Darwin curl -fSL https://github.com/xfhg/intercept/releases/latest/download/intercept-darwin_amd64 -o intercept --- Linux curl -fSL https://github.com/xfhg/intercept/releases/latest/download/intercept-linux_amd64 -o intercept --- Windows curl -fSL https://github.com/xfhg/intercept/releases/latest/download/intercept-windows_amd64 -o intercept.exe
获取样本进行快速扫描：
curl -fSLO https://github.com/xfhg/intercept/releases/latest/download/_examples.zip
现在，我们需要分析的代码已经存储在一个examples/文件夹中了，在开始之前，我们需要查看策略文件中的可选策略类型：
- scan : where we enforce breaking rules on matched patterns - collect : where we just collect matched patterns
我们给出的演示样例将会做以下几件事情：
1、扫描目标代码中是否存在私钥：我们需要保证策略的fatal:true，并且不接受任何异常，即enforcement:true。设置环境：保证此策略将在所有环境上强制执行。
2、扫描模块是否来自兼容源而不是本地或git：我们需要保证策略的fatal:true，并且环境必须为PROD，即environment:prod。这个策略可以接受本地异常：enforcement:false。
3、收集模块使用之外的terraform资源实例。
包含上述扫描策略和收集策略的策略文件如下（ examples/policy/simple.yaml ）：
# This banner is shown on the start of the scanning report, # use it to point out important documentation/warnings/contacts
Banner: | Banner text here, drop documentation link or quick instructions on how to react to the report Rules: # This is the main policy block, all rules will be part of this array # This is a rule structure block # Each rule can have one or more patterns (regex) # The rule is triggered by any of the patterns listed #
# Essential settings : # id : ( must be unique ) # type : ( scan | collect ) # fatal : ( true | false ) # enforcement : ( true | false ) # environment : ( all | anystring) # All other settings are free TEXT to complement your final report - name: Private key committed in code id: 1 description: Private key committed to code version control solution: error: This violation immediately blocks your code deployment type: scan enforcement: true environment: all fatal: true
patterns: - \s*(-----BEGIN PRIVATE KEY-----) - \s*(-----BEGIN RSA PRIVATE KEY-----) - \s*(-----BEGIN DSA PRIVATE KEY-----) - \s*(-----BEGIN EC PRIVATE KEY-----) - \s*(-----BEGIN OPENSSH PRIVATE KEY-----) - \s*(-----BEGIN PGP PRIVATE KEY BLOCK-----)
# Another scan rule - name: Compliant module source id: 5 description: Modules should not be sourced locally nor from git error: This breach blocks your deployment on production environments type: scan solution: environment: prod fatal: true enforcement: false patterns: - source\s*.*\.git" - \s+source\s*=\s*"((?!https\:).)
# A different type of policy rule that just collects findings matched with the patterns listed - name: Collect sparse TF resources outside of modules. description: The following resources were detected outside of compliant module usage type: collect patterns: - (resource)\s*"(.*)"
# These are the messages displayed at the end of the report # Clean for no finds # Warning for at least one non-fatal find # Critical for at least one fatal find ExitCritical: "Critical irregularities found in your code" ExitWarning: "Irregularities found in your code" ExitClean: "Clean report"
