This rule detects when important or interesting Windows services are terminated unexpectedly, which may indicate possible malicious activity or system anomalies. It specifically looks for Event ID 7023 generated by the Service Control Manager, which signals that a service has stopped due to various reasons. The rule includes specific service names associated with security features such as Antivirus, Firewall, and Windows Defender, indicating a focus on critical security services. Additionally, it checks for specific binary patterns that may correspond to these services, suggesting a direct correlation with potential evasion techniques used by attackers. The conditions set within the rule require both the correct provider name and the presence of important materials in the termination logs to trigger an alert, thereby minimizing false positives. The importance of monitoring such events is underscored by the definition of a high-level alert status, showing that such terminations can often be a prelude to malicious activities or system compromises.
