+description: This correlation rule focuses on detecting potential threats associated with MITRE ATT&CK T1649 (Steal or Forge Authentication Certificates). The rule is designed to identify instances where 5 or more analytics related to Windows Certificate Services analytic story that are triggered within a specified time frame, which may indicate a potential attack in progress. By aggregating these analytics, security teams can swiftly respond to and investigate any suspicious activities, enhancing their ability to protect critical assets and prevent unauthorized access to sensitive information.

+how_to_implement: The Windows Certificate Services analytic story must have 5 or more analytics enabled. In addition, ensure data is being logged that is required. Modify the correlation as needed based on volume of noise related to the other analytics.
+known_false_positives: False positives may be present based on automated tooling or system administrators. Filter as needed.
