Introduction to cisco-asa.9.12.4.58.SPA.csp
The cisco-asa.9.12.4.58.SPA.csp is a critical security maintenance release for Cisco ASA 5500-X Series firewalls running Adaptive Security Appliance (ASA) Software 9.12.4. Released in Q4 2024 under Cisco’s quarterly security update cycle, this package addresses multiple Common Vulnerabilities and Exposures (CVEs) while enhancing platform stability for enterprise network security deployments.
Designed for ASA 5506-X, 5508-X, and 5516-X hardware models, this software bundle combines ASA OS version 9.12.4.58 with updated cryptographic libraries. It maintains backward compatibility with configurations from ASA 9.12.x releases, making it essential for organizations requiring PCI-DSS 3.2.1 compliance in financial and healthcare sectors.
