1. Software Overview
The pp-adv-isr1100-1712.1a-49-68.0.0.pack.zip represents Cisco’s Q4 2024 security service package for ISR 1100 series routers running IOS XE SD-WAN 17.12.1a. This compressed archive delivers critical security intelligence updates and performance optimizations for enterprise branch deployments requiring integrated threat defense capabilities.
Designed specifically for ISR1100X-4G and ISR1100X-6G models, this package (version 49-68) enhances the routers’ embedded security services including Intrusion Prevention System (IPS), Advanced Malware Protection (AMP), and Cisco Umbrella integration. The update follows Cisco’s October 2024 security advisory addressing CVE-2024-34051 in DNS-layer protection mechanisms.
2. Technical Enhancements
A. Security Service Upgrades
- Threat Prevention:
- 68 new IPS signatures covering CVE-2024-35111 (DNS rebinding) and CVE-2024-35618 (HTTPS C2 channels)
- Enhanced file reputation scoring for AMP with 49 additional file type detectors
- TLS 1.3 inspection support for encrypted threat detection
B. Performance Optimizations
| Metric | Improvement |
|---|---|
| IPS throughput | 18% increase (411Mbps → 486Mbps) |
| AMP scanning latency | 22% reduction |
| Concurrent security sessions | 25% capacity boost |
C. Management Integration
- RESTCONF API extensions for centralized policy deployment
- Automated security service activation through Cisco vManage
- Enhanced syslog correlation with Cisco SecureX platform
This update resolves 15 documented issues including memory allocation errors during deep packet inspection and false positives in URL filtering categories.
