Introduction to cisco-asa-fp2k.9.14.4.24.SPA

This maintenance release for Cisco Firepower 2100 series appliances addresses 14 CVEs disclosed in Cisco Security Advisory cisco-sa-20240314-asa, including critical vulnerabilities in IKEv2 fragmentation handling and SSL/TLS session resumption mechanisms. Designed for enterprises requiring PCI-DSS compliance, the 9.14.4.24 build enhances threat intelligence synchronization capabilities while maintaining backward compatibility with ASA 9.12.x configurations.

The software package supports Firepower 2110/2120/2130/2140 models running FXOS 2.8.1.172+ firmware, providing unified management integration with Cisco Defense Orchestrator 3.0+ and Firepower Management Center 7.2+. This version introduces automated policy conversion tools for organizations migrating from legacy ASA 5500-X platforms.
