This detection rule identifies attempts to record audio using the 'arecord' utility on Linux systems. The rule is based on the execution of the 'arecord' command with specific arguments that suggest audio capture activity. It employs the SYSTEM audit logs to capture events crafted specifically for the execution of the command to gauge whether user activity may involve unauthorized audio recording. This is important for ensuring both compliance and privacy as it can potentially flag malicious behavior where audio is recorded without consent. Proper logging and real-time monitoring can help in responding to such events effectively, enhancing an organization's overall security posture.
