Windows Firewall Settings Have Been Changed

Sigma Rules

View Source
Summary
This detection rule identifies unauthorized changes to Windows Firewall settings by monitoring specific event IDs associated with configuration modifications. The detection mechanism is triggered when any of the designated Event IDs—2002, 2083, 2003, 2082, or 2008—are logged. These events indicate activities such as creation, modification, or deletion of firewall rules and settings, which are critical for maintaining network security and preventing unauthorized access. This rule is part of the defense evasion tactics in cybersecurity, aiming to safeguard the integrity of firewall configurations which play a fundamental role in protecting Windows systems from external threats. A persistent monitoring of such changes is essential for early detection of potential security breaches.
