The Examination module of Zeek has two components that equally work on signature detection and anomaly Evaluation. The first of these analysis resources is the Zeek party engine. This tracks for triggering gatherings, for instance a new TCP link or an HTTP ask for.

An Intrusion Detection Technique (IDS) displays network visitors for unconventional or suspicious action and sends an notify for the administrator. Detection of anomalous exercise and reporting it on the network administrator is the key perform; nevertheless, some IDS program will take action based upon principles when destructive exercise is detected, by way of example blocking sure incoming targeted traffic.
