Abstract

With network functions virtualization, an organization gains an ability to provide a much more agile security infrastructure. In this paper we focus on vulnerabilities and challenges created by this new flexibility itself. In particular, using Bro as a case study, we present i) a framework for testing Bro scripts using a packet traces, ii) a complementary framework for testing the performance impact of Bro scripts, iii) a continuous integration system for triggering automatic testing in response to code changes. With this system, security administrators are protected against logic errors in new and modified scripts as well as performance degradation.
从兄弟设置的变化中获得惊喜
通过网络功能虚拟化,组织获得了提供更加敏捷的安全基础设施的能力。在本文中,我们将重点讨论这种新的灵活性本身所带来的脆弱性和挑战。特别是,使用Bro作为案例研究,我们提出i)一个使用包跟踪测试Bro脚本的框架,ii)一个用于测试Bro脚本的性能影响的补充框架,iii)一个用于触发响应代码更改的自动测试的持续集成系统。使用此系统,安全管理员可以避免新脚本和修改脚本中的逻辑错误以及性能下降。
