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)

Compatibility and Requirements

Supported Hardware

Cisco Model Minimum IPS Version Chassis Compatibility
NM-CIDS 4.1(2) Catalyst 6509-E
