Restricted Software Access By SRP

Sigma Rules

View Source
Summary
This rule is designed to detect unauthorized attempts to access software applications that are restricted by Software Restriction Policies (SRP) on Windows systems. SRP is a feature that allows administrators to control which applications can run on computers in a Windows environment, thereby reducing potential attack surfaces by preventing the execution of unauthorized software. The detection rule focuses on specific event IDs generated when SRP policy actions are taken, particularly those indicating access was denied based on configured software restrictions. By monitoring these events, security teams can identify possible evasion tactics employed by attackers attempting to circumvent application controls. The rule looks for events logged by the Microsoft-Windows-SoftwareRestrictionPolicies provider, particularly Event IDs 865 through 868 and 882, which correspond to various SRP enforcement actions. This makes it a critical tool for maintaining a secure application environment in organizations utilizing SRPs.
