安全事件响应系统设计探讨
层出不穷的安全事件使大家意识到，企业安全体系不是部署入侵检测，防火墙等安全设备就够了。企业安全团队在应对越来越复杂的安全态势力不从心。传统安全产品使安全团队淹没在巨量的告警日志中无法自拔，不知所错。安全研究人员围绕着数据收集，数据分析和响应策略提出了很多模型。其中洛克希德马丁提出的攻击链模型对攻击行为给出了比较清晰的刻画，为如何在海量日志里准确的刻画攻击路径及攻击危害提供了思路。ISCM则提出以主动、自动化和基于风险的方法设计安全响应策略。NASA关于基于持续监控制定安全事件响应机制的报告，对如何构建安全运营系统提出了指导。
Discussion on Designing a Security Incident Response System
As security events emerge in an endless stream, we have realized that only deploying intrusion detection devices and firewalls is hardly enough to constitute a satisfactory enterprise security system. Also, the enterprise security team often finds it more difficult to effectively control the increasingly complicated security situation. Traditional security products generate huge amounts of alert logs, checking of which wears security teams down. Meanwhile, security researchers put forward many a model that centers on data collection, data analysis, and response policies.
