GraMSec 2018

The Fifth International Workshop on
Graphical Models for Security

Oxford, UK - July 8, 2018

Co-located with CSF 2018, in conjunction with FLoC 2018



Mike Fisk, Chief Information Officer at Los Alamos National Laboratory, NM, USA


Intrusion Tolerance in Complex Cyber Systems


We will discuss intrusion tolerance as a desirable property of cyber systems and discuss the relationship between intrusion tolerance and resilience. Intrusion-tolerant complex systems maintain certain security properties even when components of those systems are compromised. We will examine some ways to quantify intrusion tolerance using graphical models of complex cyber systems with a focus on the misuse of authentication credentials and the exploitation of trust relationships. Finally, we will provide some examples of the impact of this analysis on real-world policy decisions.
