What happened

The file {{ @file.path }} was modified by the process {{ @process.comm }}, potentially disabling security tools.

Goal

Detect unauthorized changes to auditd.

Strategy

This rule generates a signal when the configuration for auditd is modified or an auditd rule is modified.

Triage and response

1. Determine the source of the change, and determine if it is authorized or expected.
2. If it is not expected, develop a timeline by reviewing the related signals and any relevant logs.
3. Attempt to contain the compromise, possibly by terminating the workload, depending on the stage of attack. Follow your organization’s internal processes for investigating and remediating compromised systems.
