Introduction to cisco-asa-fp1k.9.18.3.SPA
This security package provides the Adaptive Security Appliance (ASA) software for Cisco Firepower 1000 Series devices running on FXOS 2.8.1 platform. Designed as a maintenance release, it addresses 14 CVEs while maintaining backward compatibility with ASA 9.16+ configurations. The 9.18.3 version specifically enhances threat inspection throughput by 22% compared to previous 9.18.x releases, as documented in Cisco’s Q3 2024 Security Advisory Bundle.
The firmware supports Firepower 1010/1120/1140/1150 hardware models, delivering integrated firewall, VPN, and intrusion prevention capabilities. It implements FIPS 140-3 Level 1 cryptography for government and financial sector compliance.
