This detection rule identifies modifications to Windows Firewall rules, which could signify unauthorized attempts to alter critical security settings. Changes to firewall rules may weaken defenses, allowing for malicious activity or obstructing legitimate traffic. The detection utilizes Windows Security Event Logs, specifically focusing on Event ID 4947, which records any modification of firewall rules. The logging details include the rule in question, protocols affected, ports used, the application path involved, and the user who executed the change. Security professionals are encouraged to monitor these events closely, cross-reference them with other security logs, and analyze any unexpected modifications to uphold the security posture of the network.
