Introduction to cisco-asa.9.16.2.7.SPA.csp

This security maintenance package provides critical updates for Cisco Firepower 2100 and 4100 series appliances running Adaptive Security Appliance (ASA) software 9.16.2. Released in Q1 2024 under Cisco Security Advisory ID 2024-ASA-0215, it resolves 11 CVEs including memory management vulnerabilities (CSCwi94011) and TLS session handling flaws (CSCwj29205). Designed for enterprises requiring FIPS 140-2 compliance, this build introduces enhanced cluster synchronization protocols and improves encrypted traffic inspection efficiency by 18% compared to previous 9.16.x versions.

The software supports Firepower 2110/2120/2130/4140 hardware platforms with FXOS 2.7.3+ requirements, delivering integrated threat prevention capabilities for hybrid cloud environments. The .csp extension confirms this as a consolidated security package containing both platform firmware and ASA component updates.
