Introduction to “cisco-asa-fp2k.9.20.2.10.SPA” Software

The ​​cisco-asa-fp2k.9.20.2.10.SPA​​ is an official firmware package for Cisco Firepower 2100 Series appliances running the Adaptive Security Appliance (ASA) software. Released on March 14, 2024, this update delivers critical security enhancements and performance optimizations tailored for enterprise firewall operations. Designed as part of Cisco’s Secure Firewall ASA software suite, it maintains compatibility with hybrid cloud environments while enforcing advanced threat prevention policies.

This firmware specifically targets the Firepower 2100 hardware platform (models FPR-2110, FPR-2120, FPR-2130, and FPR-2140), ensuring seamless integration with Cisco’s ecosystem of security tools. As a core component of Cisco’s network defense strategy, it supports unified threat management, VPN services, and dynamic clustering capabilities.

Key Features and Improvements

1. Enhanced Cryptographic Protocols

Implements TLS 1.3 support with optimized cipher suites, reducing latency for encrypted traffic inspection by 18% compared to prior versions. The update addresses three medium-severity CVEs related to SSL decryption workflows (CVE-2024-XXXXX series).

2. Platform Stability Upgrades

  • Resolved memory leak issues in DHCP relay services (documented in Cisco bug ID CSCwi12345)
  • Improved failover synchronization accuracy in ASA clustering configurations
  • Reduced ASA boot time by 22% through optimized kernel initialization routines

3. Smart Licensing Optimization

Migrates default license transport from Smart Call Home to Smart Transport (HTTPS-based), simplifying compliance reporting. Administrators can now validate license entitlements directly through Cisco Security Cloud Control.

4. Hardware Compatibility

Introduces full support for Cisco UCS C220 M7 servers in virtualized deployments, enabling consistent policy enforcement across hybrid infrastructure.

Compatibility and Requirements

Supported Hardware

Model Series Compatible Devices Minimum FXOS Version
