Introduction to Cisco_Secure_FW_Mgmt_Center_Upgrade-7.4.0-118.sh.REL.tar
The Cisco_Secure_FW_Mgmt_Center_Upgrade-7.4.0-118.sh.REL.tar upgrade package enables administrators to update Cisco Secure Firewall Management Center (FMC) Virtual appliances to version 7.4.0. Released in Q4 2024 as part of Cisco’s long-term support (LTS) cycle, this maintenance release focuses on stability improvements, security hardening, and hybrid cloud management enhancements for firewall policy orchestration.
Compatible with Firepower Management Center Virtual 300 (FMCv300) appliances deployed on VMware ESXi 6.5-8.0 and KVM hypervisors, this 1.69 GB upgrade file resolves 23 documented vulnerabilities while maintaining backward compatibility with FTDv 7.0.x-7.4.x managed devices. It serves as a critical update for environments requiring PCI-DSS 4.0 compliance or NIST 800-53 rev5 audit readiness.
