Azure Virtual Network Device Modified or Deleted

Identifies when a virtual network device is being modified or deleted. This can be a network interface, network virtual appliance, virtual hub, or virtual router.

Detection logic

Detection requirements

Log source product: azure
Log source service: activitylogs

Known benign triggers

Virtual Network Device 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.
Virtual Network Device modified or deleted from unfamiliar users should be investigated. If known behavior is causing false positives, it can be exempted from the rule.

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.
