Introduction to Cisco_Firepower_Mgmt_Center_Upgrade-7.0.4-55.sh.REL.tar
The Cisco_Firepower_Mgmt_Center_Upgrade-7.0.4-55.sh.REL.tar is a critical security maintenance package for Cisco Firepower Management Center (FMC) 7.0.x deployments, designed to address vulnerabilities and enhance operational stability in enterprise network security environments. Released in Q1 2024, this update specifically resolves CVE-2024-20351 – a Snort rule processing flaw affecting encrypted traffic inspection – while maintaining compatibility with Firepower Threat Defense (FTD) appliances and virtual instances.
This upgrade package supports both physical FMC 1600/2600/4500 series appliances and virtual FMC instances (FMCv) deployed on VMware ESXi 6.7–8.0 or KVM hypervisors. It ensures uninterrupted policy synchronization for environments managing up to 750 sensors and 300 million security events, aligning with NIST SP 800-53 compliance requirements.
Key Features and Improvements
Version 7.0.4-55 delivers mission-critical enhancements for enterprise security operations:
