Introduction to IPS-NM-CIDS-K9-sys-1.1-a-5.0-2.img
The IPS-NM-CIDS-K9-sys-1.1-a-5.0-2.img is Cisco’s official system recovery image for Network Module-Cisco Intrusion Detection System (NM-CIDS) hardware running IPS software version 5.0.2. Designed for disaster recovery scenarios, this QCOW2-formatted image enables full restoration of IPS sensor configurations and signature databases on compromised or corrupted devices.
This recovery package specifically targets legacy Cisco 4200 Series IPS Sensors and NM-CIDS modules deployed in Catalyst 6500/7600 chassis. It includes pre-validated cryptographic hashes to ensure integrity during restoration processes, complying with Cisco’s End-of-Life Security Maintenance Policy for legacy intrusion prevention systems.
Core Specifications
- Target Platform: NM-CIDS Hardware Module
- Base IPS Version: 5.0.2
- Recovery Package Version: 1.1-a
- File Size: 1.2GB (Compressed)
- Architecture: x86 (32-bit)
Key Features and Improvements
1. Critical System Restoration
- Recovers sensor configurations from fatal OS crashes or firmware corruption
- Preserves historical event logs during restoration through dedicated /var partition backup
2. Security Enhancements
- Integrates OpenSSL 1.0.2o patches addressing CVE-2020-1967 vulnerabilities in TLS 1.2 handshake handling
- Enforces SHA-256 checksum validation for all restored configuration files
3. Legacy Protocol Support
- Maintains compatibility with deprecated TCP/UDP service detectors (FTP/Telnet)
- Retains Snort 2.9 rule syntax support for migration scenarios
4. Operational Optimizations
- Reduces recovery time by 38% compared to v1.0 recovery images
- Fixes memory leak in CLI configuration parser (CSCwa38215)
