OWL-Based Intelligent Security Audit

The disclosure herein describes a system for facilitating intelligent auditing of security log records. A set of security policies are converted into a set of web ontology language (OWL)-based rules. At the same time, log records are also converted into an OWL-based format. The system then applies the OWL-based rules, which can be in the form of a number of semantic web rule language (SWRL) statements, to the OWL-formatted log data. As a result, the system can identify potential security breaches which cannot be easily identified by conventional auditing methods.
