Efficiency of network event logs as admissible digital evidence

The large number of event logs generated in a typical network is increasingly becoming an obstacle for forensic investigators to analyze and use to detect and verify malicious activities. Research in the area of network forensic is trying to address the challenge of using network logs to reconstruct attack scenarios by proposing event correlation models. In this paper we introduce a new network forensics model that makes network event-logs admissible in the court of law. Our model collects available logs from connected network devices, applies decision tree algorithm in order to filter anomaly intrusion, then re-route the logs to a central repository where event-logs management functions are applied.
