This detection rule identifies and alerts on any changes to service security descriptors within the Windows operating system, specifically when a new deny Access Control Entry (ACE) is set through the 'sc.exe' command-line tool, which is used for service control management. By monitoring for the execution of 'sc.exe' with the 'sdset' option, this analytic can signal potential malicious activities such as privilege escalation or evasion of defenses by attackers. It employs data from various sources, including Sysmon and Windows Event Logs, to track and analyze process executions related to service modification commands, aiding in the early detection of security threats related to Windows services.
