小编给大家分享一下Intercept有什么用,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
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。
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”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。
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。
# 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
首先,根据自己的平台下载最新版本的INTERCEPT:
--- Darwincurl -fSL https://github.com/xfhg/intercept/releases/latest/download/intercept-darwin_amd64 -o intercept--- Linuxcurl -fSL https://github.com/xfhg/intercept/releases/latest/download/intercept-linux_amd64 -o intercept--- Windowscurl -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):
