Abstract:

Cyber resilience usually refers to the ability of an entity to detect, respond to, and recover from cybersecurity attacks to the extent that the entity can continuously deliver the intended outcome despite their presence. Cybersecurity tools such as intrusion detection and prevention systems usually generate far too many alerts, indicators, or log data, many of which do not have obvious security implications unless their correlations and temporal causality relationships are determined. In this talk, I will present methods to first estimate the infected and exploited assets and then take recovery and preventive actions using autonomous agents, deep learning, and graphs. Autonomous adversary and defender agents are designed such that the adversary agent can infer the adversary activities and intentions, based on cybersecurity observations and measurements, while the defender agent aims at estimating the best reactive and pro-active actions to protect assets and mitigate the adversary activities. The graph thinking and causality analysis of cyber infection and exploitation help predict the infection states of some assets. This prediction data of infections are taken as input data by deep reinforcement learning to train agents for determining effective actions. This talk will discuss some preliminary results from the development of building an automated system of autonomous agents to provide cyber resiliency over networks.
