This detection rule identifies when Windows Defender's Real-time Protection has been disabled. The primary event of interest is Event ID 5001. Disabling this feature is typically a defensive evasion tactic used by malicious actors to allow malware to operate undetected. Given that processes for disabling can occur without sufficient logging to determine whether an administrator or a malicious actor initiated the action, it may be advisable to treat frequent occurrences as lower severity or medium level alerts. The rule provides references for additional context around the implications of disabling Windows Defender, which can help organizations assess risks and comply with security best practices.
