Introduction to cisco-secure-client-win-5.0.00529-webdeploy-k9.pkg Software

This web deployment package contains Cisco Secure Client 5.0.00529 for Windows environments, designed to streamline enterprise VPN deployments through centralized configuration management. As part of Cisco’s Secure Client suite, it enables encrypted remote access to corporate networks while maintaining compliance with NIST SP 800-207 Zero Trust Architecture standards.

The software officially supports ​​Windows 10 (64-bit) and Windows 11 systems​​ and integrates with Cisco ASA 5500-X series firewalls running OS 9.16(3.19)+. Cisco’s Q4 2023 release notes confirm this version addresses 12 CVEs identified in security audits, including critical vulnerabilities in TLS session handling.

Key Features and Improvements

  1. ​​FIPS 140-2 Cryptographic Compliance​​

    • Implements OpenSSL 3.0.8 libraries with AES-256-GCM encryption for government-grade security
    • Enforces TLS 1.2 as minimum protocol standard across all VPN connections

  2. ​​Automated Deployment Enhancements​​

    • Supports silent installations via Microsoft Endpoint Manager with preconfigured XML templates
    • Enables bulk certificate provisioning through SCEP/NDES integration

  3. ​​Performance Optimization​​

    • Reduces memory consumption by 15% through streamlined IKEv2 negotiation processes
    • Accelerates VPN session recovery time by 30% after network interruptions

  4. ​​Vulnerability Mitigation​​

    • Resolves CVE-2023-44228 (TLS session resumption vulnerability)
    • Addresses CVE-2023-44901 (IPsec IKEv2 memory exhaustion flaw)

Compatibility and Requirements

Supported Windows Versions Minimum ASA OS Processor Architecture RAM Requirement
Windows 11 22H2 9.16(3.19) x64 4GB
Windows 10 21H2 9.14(1.11) x64 4GB
Windows 11 ARM64 9.16(4.48) ARM64 8GB

​​Critical Notes​​:

  • Incompatible with Windows 8.1 and earlier due to deprecated cryptographic libraries
  • Requires manual configuration for ASA clusters running mixed OS versions below 9.14(1.11)
  • Disables connections to legacy ASA 5505/5510 models per Cisco’s 2023 EoL policy
