入侵警报关联中的数据约简

Data Reduction in Intrusion Alert Correlation

Gianni Tedesco, Uwe Aickelin

摘要:

网络入侵检测传感器通常建立在网络流量的低级别模型上。这意味着它们的产出同样很低,因此难以分析。入侵警报关联是通过将相关警报分组在一起来自动执行某些分析的任务。攻击图为这种分析提供了直观的模型。不幸的是,警报泛滥攻击仍然会导致传感器上的服务丢失,并且在执行攻击图关联时,输出图中可能包含大量无关警报。这掩盖了真正攻击的精细结构,使人类操作员更难辨别。本文探讨了修改的相关算法,试图尽量减少这种攻击的影响。

英文摘要:

Network intrusion detection sensors are usually built around low level models of network traffic. This means that their output is of a similarly low level and as a consequence, is difficult to analyze. Intrusion alert correlation is the task of automating some of this analysis by grouping related alerts together. Attack graphs provide an intuitive model for such analysis. Unfortunately alert flooding attacks can still cause a loss of service on sensors, and when performing attack graph correlation, there can be a large number of extraneous alerts included in the output graph. This obscures the fine structure of genuine attacks and makes them more difficult for human operators to discern. This paper explores modified correlation algorithms which attempt to minimize the impact of this attack.
