Characterizing university network usage with Active Directory event logs
… of the network by analyzing Windows event logs generated at Active Directory domain controllers. We want to see what network activity looks like as a first step in identifying and modeling network lateral movement. We characterize network activity, access behavior, most frequent …

Analyzing audit trails in the Aeolus security platform
… on collecting these audit trails in the form of event logs. This thesis presents a model for representing these events and a system for analyzing them. In addition to allowing users to issue SQL queries over the audit log, this analysis system provides mechanisms for active monitoring of events. …

Mining intrusion detection alert logs to minimise false positives & gain attack insight
Utilising Intrusion Detection System (IDS) logs in security event analysis is crucial in the process of assessing, measuring and understanding the security state of a computer network, often defined by its current exposure and resilience to network attacks. Thus, the study of understanding network …
