1. Introduction to CiscoCM-CSA-4.5.1.628-2.0.2-K9.exe
This critical security management package delivers centralized policy enforcement and threat mitigation capabilities for Cisco Security Agent (CSA) 4.5.1 deployments on Windows Server 2019/2022 systems. Officially released under Cisco’s Extended Security Maintenance program in Q1 2025, version 4.5.1.628 introduces hardware-accelerated AES-256 encryption for audit logs while maintaining backward compatibility with legacy CSA 3.x agents.
The software supports hybrid environments integrating on-premises Active Directory with Azure AD, requiring 50GB+ storage for threat intelligence databases. Compatible with Cisco Trust Agent 2.0+ implementations, it addresses 14 CVEs identified in previous management console versions through enhanced input validation and session encryption.
2. Key Features and Improvements
