Azure Network Firewall Policy Modified or Deleted

Identifies when a Firewall Policy is Modified or Deleted.

Detection logic

Detection requirements

Platform: IaaS
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source product: azure
Log source service: activitylogs

Known benign triggers

Firewall Policy being modified or deleted may be performed by a system administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment.
Firewall Policy modified or deleted from unfamiliar users should be investigated. If known behavior is causing false positives, it can be exempted from the rule.

References

Links the source published beside this detection. Reference is the link the source wrote, unmodified. Class is decided by this catalogue from the host and path, not stated by the source. Cited by counts published detections citing the same resource, including this one, and the sources beneath it count the repositories this catalogue ingests, which is not the same as independent research.

Detections can measure how the public catalogue is used — which detections people look for, and which pages bring them here. It sets a cookie that recognises this browser for 180 days. It is never linked to an account and never follows you to other sites. Privacy notice
