Collection Method

This collector parses the necessary data from the network_interfaces table.

Usage

This evidence is crucial for forensic investigations as it provides network configuration information. It helps investigators understand network topology, detect unauthorized network access, and investigate network-based attacks. The data can reveal network misconfigurations, unauthorized connections, and potential network vulnerabilities. Analysts can use this information to identify network compromises, trace network activities, and assess network security posture.

Notes

This data may contain sensitive information that should be handled according to data protection requirements. Ensure proper chain of custody is maintained during collection and analysis.
