Introduction to cisco-asa-fp1k.9.18.1.3.SPA

This firmware package provides critical security updates and feature enhancements for Cisco Firepower 1000 Series appliances running Adaptive Security Appliance (ASA) Software 9.18.x. Designed specifically for FPR-1120/FPR-1150 models, this maintenance release resolves 12 CVEs from previous versions while introducing hardware-accelerated TLS 1.3 inspection capabilities.

The “.SPA” extension confirms this as a signed package compatible with Cisco’s Smart Software Manager licensing system. It implements FIPS 140-3 validated cryptographic modules required for U.S. federal government deployments and financial sector compliance frameworks like PCI-DSS v4.0.
