Quantitative Analysis of Network Security with Abstract Argumentation

摘要

An Abstract Argumentation Framework (AAF) represents a useful technique for the analysis of arguments supporting or discouraging decisions (i.e., information can be in conflict). In particular, we apply Abstract Argumentation to support the administration of security in computer networks. Our approach captures the high-level topology of a system and helps to specify which and where security countermeasures are more appropriate. We design a quantitative analysis on AAFs (modelling our domain knowledge) with the purpose to compare different decisions and select the most suitable one to protect the critical assets.
