Azure VPN Connection Modified or Deleted

Sigma Rules

View Source
Summary
This detection rule is designed to monitor changes made to VPN connections within the Azure cloud environment. Any modifications (WRITE operations) or deletions (DELETE operations) of VPN connections are logged through the Azure activity logs. The rule specifically looks for operations that involve writing or deleting VPN gateways. Because these actions can have significant security implications—if unauthorized changes are made—this detection rule is categorized under a medium-level alert. Administrators should be cautious, as legitimate administrative actions are common, which leads to a potential for false positives. The recommendations suggest verifying user identities and behavior patterns if such alerts are triggered, especially if they originate from unfamiliar sources.
