摘要:

结合攻击图和网络地形,使用强化学习(RL)来开发与确定用于企业网中的数据渗出的最佳路径相关联的奖励和状态。这项工作建立在以前的皇冠上的宝石(CJ)识别,重点是计算最佳路径的目标目标,对手可能会遍历到妥协的CJ或主机在他们的附近。这项工作颠覆了以前的CJ方法,该方法基于数据被盗的假设,现在必须悄悄地从网络中泄露。RL被用来支持奖励函数的开发,该奖励函数基于对对手期望减少检测的那些路径的识别。结果表明,一个相当大的网络环境有前途的性能。

英文摘要:

Reinforcement learning (RL), in conjunction with attack graphs and cyber terrain, are used to develop reward and state associated with determination of optimal paths for exfiltration of data in enterprise networks. This work builds on previous crown jewels (CJ) identification that focused on the target goal of computing optimal paths that adversaries may traverse toward compromising CJs or hosts within their proximity. This work inverts the previous CJ approach based on the assumption that data has been stolen and now must be quietly exfiltrated from the network. RL is utilized to support the development of a reward function based on the identification of those paths where adversaries desire reduced detection. Results demonstrate promising performance for a sizable network environment.
