EXECUTIVE SUMMARY
This document establishes comprehensive anti-virus and security patch management procedures for enterprise security systems, implementing automated patch management, regular security updates, and anti-malware protection across all system components to maintain security posture and protect against evolving threats.
Current Implementation Status:
- Current State: No external anti-virus software is currently deployed
