1. Software Overview

CiscoCM-CSA-4.0.2.629-1.1.6-K9.exe delivers FIPS 140-3 validated endpoint security controls for Cisco Unified Communications Manager (UCM) environments. This Windows service module provides real-time threat prevention for voice infrastructure servers, specifically hardening Cisco Media Convergence Servers (MCS) against zero-day attacks targeting SIP and SCCP protocols.

Released on February 15, 2025, the 1.1.6-K9 build introduces quantum-safe encryption for configuration backups while maintaining compatibility with UCM 14.0(1)SU4+ clusters. The executable integrates with Cisco Identity Services Engine (ISE) 3.3+ for automated device posture validation.

2. Technical Enhancements

Version 4.0.2.629-1.1.6-K9 implements three critical security upgrades:

  1. ​Protocol Anomaly Detection​
    Analyzes SCCP/SIP traffic patterns using machine learning models trained on 2024 threat intelligence feeds, blocking 37% more malicious payloads than v4.0.1.

  2. ​Memory Protection​
    Enforces W^X (Write XOR Execute) policies on UCM service processes through hardware-assisted CET (Control-flow Enforcement Technology).

  3. ​Encrypted Configuration Backups​
    Implements CRYSTALS-Kyber lattice-based cryptography for UCM disaster recovery files, aligning with NIST Post-Quantum Cryptography standards.

3. Compatibility Matrix

Supported Platforms Minimum Requirements Restrictions
Cisco UCS C220 M5 Windows Server 2022 Datacenter 64GB RAM
UCS C240 M6 UCM 14.0(1)SU4 No Hyper-V support
Virtualized UCM VMware ESXi 7.0U3+ Requires vTPM 2.0

​Release Date​​: 2025-02-15
​Known Issues​​:

  • Conflicts with third-party AV using kernel-mode drivers
  • Disables TLS 1.0/1.1 by default during installation

4. Operational Constraints

  1. ​Resource Requirements​

    • 2.4GHz CPU minimum for real-time traffic inspection
    • 500MB persistent storage for threat intelligence cache
  2. ​Policy Limitations​

    • Maximum 256 concurrent security policies
    • No backward compatibility with UCM 11.x configurations
  3. ​Third-Party Integration​

    • Requires manual certificate import for non-Cisco PKI systems
    • Disables Windows Defender Firewall during service operation

5. Verified Acquisition Process

​Entitled Organizations​​:

  1. Access Cisco Software Center with Smart Account privileges
