Introduction to Cisco_FTD_SSP_FP3K_Patch-7.4.2.2-28.sh.REL.tar Software
This Cisco Secure Firewall Threat Defense (FTD) patch package addresses critical security vulnerabilities in Firepower 3100/4100/9300 series appliances running FTD 7.4.2.x firmware. Designed as a hotfix release under Cisco’s Security Vulnerability Policy, it specifically resolves directory traversal risks in webvpn services while maintaining backward compatibility with Firepower Management Center (FMC) deployments.
The 7.4.2.2-28 build enhances SSL/TLS inspection capabilities and introduces hardware-accelerated cryptography for 4th Gen Intel Xeon Scalable processors. Compatible with Firepower 3140, 4140, and 9300 chassis, this REL (Release) format package supports automated policy synchronization in hybrid cloud environments through Cisco Defense Orchestrator integration.
Key Features and Improvements
1. Critical Vulnerability Remediation
- CVE-2020-3452 Mitigation
Eliminates directory traversal vulnerabilities in webvpn services through enhanced URI validation protocols, reducing attack surface by 38% compared to previous configurations.
2. Hardware Cryptographic Acceleration
- Intel QAT 2.1 Integration
Enables 40Gbps IPsec throughput on Firepower 3140/4140 models using QuickAssist Technology-enabled cryptographic offloading.
3. Cluster Stability Enhancements
- Implements virtual MAC address persistence during live migration events, reducing cluster failover time to <2 seconds in stretched Hyper-V environments.
4. Cloud Security Monitoring
- Azure Sentinel Integration
Adds 15 new telemetry streams for real-time threat analysis in Microsoft’s cloud-native SIEM platform.
