Introduction to secapp-utd.17.02.01r.1.0.6_SV2.9.13.0_XE17.2.x86_64.tar
This security application package provides Unified Threat Defense (UTD) enhancements for Cisco Catalyst SD-WAN devices running IOS XE 17.2.x, specifically designed to address advanced network security requirements in controller-mode deployments. Compatible with ISR 4000 series routers and ASR 1000 series aggregation routers, the release integrates 8 critical security patches from Cisco’s Q4 2024 Security Advisory Bundle while introducing TLS 1.3 optimization for encrypted traffic inspection.
Officially released in February 2025, the package supports Cisco SD-WAN Manager 4.4+ architectures and provides deterministic malware scanning for encrypted 5G network slices. Its modular design enables selective activation of security services through Cisco Enterprise NFVIS 4.2, allowing concurrent operation of virtualized functions like Cisco Umbrella SIG and Firepower NGFW.
Key Features and Improvements
1. Enhanced Encrypted Traffic Analysis
- Implements TLS 1.3 Session Resumption with 40% reduced handshake latency for HTTPS inspection
- Resolves CVE-2024-32711 (CVSS 9.1): Eliminates memory leakage in encrypted DNS query processing
2. 5G Network Security
- Slice-Aware Threat Prevention: Applies distinct security policies to eMBB/mMTC/URLLC slices
- Dynamic Certificate Management: Auto-rotates Umbrella DNS root CA certificates to prevent service disruptions
3. Performance Optimization
- Vector Packet Processing (VPP) Integration: Achieves 120Gbps IPS throughput on ISR4461-X routers
- AI-Driven Pattern Recognition: Reduces false positives by 35% in encrypted malware detection
