Uncommon Connection to Active Directory Web Services

Detects uncommon network connections to the Active Directory Web Services (ADWS) from processes not typically associated with ADWS management.

Detection logic

Detection requirements

Platform: ESXi IaaS Identity Provider Linux macOS Office Suite SaaS Windows
The rule states no platform. This is derived from the ATT&CK technique it maps to.
Log source product: windows
Log source category: network_connection

Known benign triggers

ADWS is used by a number of legitimate applications that need to interact with Active Directory. These applications should be added to the allow-listing to avoid false positives.

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
