8.1.3.5 Ensure that 'File Integrity Monitoring' Component Status is Set to 'On'

Information

File Integrity Monitoring (FIM) is a feature that monitors critical system files in Windows or Linux for potential signs of attack or compromise.

FIM provides a detection mechanism for compromised files. When FIM is enabled, critical system files are monitored for changes that might indicate a threat actor is attempting to modify system files for lateral compromise within a host operating system.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.
