Introduction to Cisco_FTD_Patch-6.7.0.2-24.sh.REL.tar Software

This cumulative hotfix package provides critical security updates and stability improvements for Cisco Firepower Threat Defense (FTD) software version 6.7.0. Released as part of Cisco’s ongoing security maintenance cycle, the patch addresses multiple Common Vulnerabilities and Exposures (CVEs) while enhancing threat detection capabilities in Next-Generation Firewall (NGFW) deployments.

The software is designed for Firepower 2100/4100/9300 appliance series and FTDv virtual instances running baseline version 6.7.0. As a maintenance release, it maintains full compatibility with existing Firepower Management Center (FMC) configurations while introducing targeted security hardening measures.
