Detection Logic
data_stream.dataset:azure.activitylogs and azure.activitylogs.operation_name:"MICROSOFT.NETWORK/NETWORKWATCHERS/DELETE" and event.outcome:(Success or success)False Positives
- ⚠ Network Watcher deletions may be done by a system or network administrator. Verify whether the username, hostname, and/or resource name should be making changes in your environment. Network Watcher deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
