This detection rule is designed to identify instances where Windows services are terminated unexpectedly, specifically by monitoring events generated by the Service Control Manager. The rule focuses on Event ID 7023, which is logged when a service is terminated with an error. While service terminations can occur for various legitimate reasons, such as system updates or configuration changes, this rule helps in detecting potential misuse or attacks targeting service functionalities. The guidance suggests that while the rule is effective in identifying signal events for investigation, analysts should also be wary of false positives that can arise from legitimate service operations. Written by Nasreddine Bencherchali of Nextron Systems, this detection is part of ongoing efforts to enhance security monitoring in Windows environments.
