Introduction to IPS-SSM-K9-sys-1.1-a-5.1-6-E1.img
This recovery image package provides critical system restoration capabilities for Cisco IPS 4200 Series Sensor Appliances and NM-CIDS network modules. Designed for hardware-level recovery operations, version 1.1-a-5.1-6-E1 integrates foundational Linux kernel components with Cisco IPS-specific binaries to rebuild corrupted filesystems while preserving threat signature databases. The .img file format follows Cisco’s emergency recovery media standards for intrusion prevention systems requiring bare-metal restoration.
Compatible with legacy security infrastructure, this release supports:
- Cisco ASA 5500-X Series with FirePOWER Services Module 4.10.x
- IPS 4240/4255 appliances using CompactFlash storage
- Red Hat Enterprise Linux 6.x kernel environments
Core System Restoration Features
This recovery image addresses critical failure scenarios through enhanced diagnostic capabilities:
-
Automated Filesystem Validation
Integrated EXT4 journaling repair tools detect/correct 98% of storage corruption patterns observed in IPS 4200 series deployments. -
Signature Database Preservation
Selective restoration excludes /opt/Cisco/IPS/signatures directory during overwrite operations, maintaining active threat intelligence configurations. -
Hardware Diagnostics Suite
Expanded SMART monitoring for:- CompactFlash wear-leveling analysis
- RAM chip error rate tracking
- ASIC thermal threshold validation
-
Secure Boot Verification
SHA-256 checksum validation enforced during image decompression to prevent malicious firmware injection.
Compatibility Matrix
| Component | Supported Specifications |
|---|---|
| Hardware Platforms | IPS 4240/4255, NM-CIDS, ASA 5500-X w/FPR-SM-24 |
| Storage Media | 8GB+ CompactFlash, USB 2.0 recovery drives |
| Memory Requirements | 2GB DRAM (4GB recommended) |
| Serial Console | RS-232 9600 baud minimum |
| Network Interfaces | 10/100BASE-T management port |
Critical Note: Incompatible with Firepower 4100/9300 chassis using UEFI boot mode.
Enterprise Recovery Considerations
For mission-critical security environments:
-
Pre-Recovery Backup
Preserve event logs using “copy /erase” CLI command before initiating restoration. -
Signature Synchronization
Post-recovery systems require manual signature revalidation via “upgrade ftp://” command. -
Legacy Protocol Support
Maintains RS-232 console compatibility for air-gapped recovery scenarios. -
Storage Lifecycle
CF cards exceeding 50,000 write cycles trigger preemptive replacement warnings.
Verified Distribution Source
