From Monitoring Templates to Security Monitoring and Threat Detection
Nuno Amálio, George Spanoudakis · 2008
This paper presents our pattern-based approach to run-time requirements monitoring and threat detection being developed as part of an approach to build frameworks supporting the construction of secure and dependable systems for ambient intelligence. Our patterns infrastructure is based on templates. From templates we generate Event-Calculus formulas expressing security requirements to monitor at run-time. From these theories we generate attack signatures, describing threats or possible attacks to the system. At run-time, we evaluate the likelihood of threats from run-time observations using a probabilistic model based on Bayesian networks.
