We will first abstract a policy in common firewall policy language into an intermediate language, and then we will try to apply anomaly detection algorithms to it. The contributions made by this thesis are: 1. An analysis of various control flow instructions in popular firewall policy languages 2. Introduction of an intermediate firewall policy language, with emphasis on control flow constructs. 3. Application of Static Code Analysis to detect anomalies in firewall policy, expressed in intermediate firewall policy language. 4. Sample implementation of Static Code Analysis of firewall policies, expressed in our abstract language using Datalog language.masters thesesengCopyright and other restrictions may apply.
