Introduction to Cisco_Firepower_Mgmt_Center_Virtual_VMware-6.6.5-81.tar.gz

This VMware deployment package provides Firepower Management Center (FMC) Virtual 6.6.5 software for centralized security policy administration across Cisco Secure Firewall ecosystems. Released in Q3 2023 under Cisco Security Advisory cisco-sa-fmc-sshvuln-9y7Cxr, it addresses critical SSH protocol vulnerabilities while maintaining backward compatibility with legacy Firepower 7000/8000 series appliances. The package contains pre-configured OVF templates and VMware Tools integration for streamlined deployment.

Key components include:

  • ​​vSphere 6.5/6.7-compatible virtual appliance templates​​
  • ​​SHA-256 verified installation bundles​​
  • ​​Integrated Snort 2.9.17 intrusion prevention rules​​

Supported environments:

  • VMware ESXi 6.5 U3 / 6.7 U2 hypervisors
  • Cisco Firepower 4100/9300 hardware chassis
  • Hybrid cloud architectures with AWS EC2 integration

Key Features and Improvements

1. ​​Enhanced Security Posture​​

Resolves CVE-2023-20269 (CVSS 8.1) – a privilege escalation vulnerability in SSH service configurations through:

  • Mandatory RSA key rotation every 90 days
  • Disabled weak ciphers (arcfour/des-cbc-ssh2) by default
  • Audit logging for all CLI access attempts

2. ​​Management Optimizations​​

  • 35% faster policy deployment through object-group optimization
  • Unified dashboard for monitoring 2000+ concurrent firewall instances
  • Automated compliance reporting aligned with NIST SP 800-53 controls

3. ​​Protocol Support Upgrades​​

  • TLS 1.3 enforcement for FMC-device communications
  • BGP AS path filtering for dynamic routing policies
  • IPv6 flow visibility in connection event analytics

Compatibility and Requirements

Component Supported Versions Notes
VMware ESXi 6.5 U3 / 6.7 U2 vCenter 6.7+ required
Firepower 4100 Series Hardware Rev 2.0+ 4120/4140/4150 models only
RAM Allocation 32GB (Min) / 256GB (Max) 64GB recommended for >50 devices
Management Networks IPv4/IPv6 dual-stack MTU 1500 mandatory
