Introduction to asa-device-pkg-1.3.11.22.zip Software
This device package provides critical integration components for Cisco ASA 5500-X Next-Generation Firewalls operating in Application Centric Infrastructure (ACI) environments. Designed for hybrid cloud security deployments, version 1.3(11.22) enhances policy synchronization between ASA firewalls and Cisco APIC controllers running NX-OS 15.2(8h) or newer.
The 1.3(11.22) release implements SHA-256 signature validation for APIC API transactions and resolves 7 critical vulnerabilities identified in previous integration packages. This maintenance update specifically optimizes performance for ASA 5585-X SSP60 modules in multi-tenant data center configurations.
