Understanding Cisco IPS Software
You can download the latest Cisco IPS software from Cisco.com. You must be logged into Cisco.com to access the software download site. You set up an account with cryptographic access the first time you download software. You can sign up for IPS Alert Bulletins to receive information on the latest software releases.
When you download IPS software images from Cisco.com, you should understand the versioning scheme so that you know which files are base files, which are cumulative, and which are incremental.
Caution 
The BIOS on Cisco IPS sensors is specific to Cisco IPS sensors and must only be upgraded under instructions from Cisco with BIOS files obtained from the Cisco website. Installing a non-Cisco or third-party BIOS on Cisco IPS sensors voids the warranty.

IPS 6.x Software Release Examples
Major and Minor Updates, Service Packs, and Patch Releases
Figure 19-1 illustrates what each part of the IPS software file represents for major and minor updates, service packs, and patch releases.
Figure 19-1 IPS Software File Name for Major and Minor Updates, Service Packs, and Patch Releases
Major Update
Contains new functionality or an architectural change in the product. For example, the Cisco IPS 6.0 base version includes everything (except deprecated features) since the previous major release (the minor update features, service pack fixes, and signature updates) plus any new changes. Major update 6.0(1) requires 5.x. With each major update there are corresponding system and recovery packages.
Note
The 6.0(1) major update is only used to upgrade 5.x sensors to 6.0(1) If you are reinstalling 6.0(1) on a sensor that already has 6.0(1) installed, use the system image or recovery procedures rather than the major update.
Minor Update
Incremental to the major version. Minor updates are also base versions for service packs. The first minor update for 6.0 is 6.1(1). Minor updates are released for minor enhancements to the product. Minor updates contain all previous minor features (except deprecated features), service pack fixes, signature updates since the last major version, and the new minor features being released. You can install the minor updates on the previous major or minor version (and often even on earlier versions). The minimum supported version needed to upgrade to the newest minor version is listed in the Readme that accompanies the minor update. With each minor update there are corresponding system and recovery packages.
Service Packs
Cumulative following a base version release (minor or major). Service packs are used for the release of defect fixes with no new enhancements. Service packs contain all service pack fixes since the last base version (minor or major) and the new defect fixes being released. Service packs require the minor version. The minimum supported version needed to upgrade to the newest service pack is listed in the Readme that accompanies the service pack. Service packs also include the latest engine update. For example, if service pack 6.0(3) is released, and E3 is the latest engine level, the service pack is released as 6.0(3)E3.
Patch Release
Used to address defects that are identified in the upgrade binaries after a software release. Rather than waiting until the next major or minor update, or service pack to address these defects, a patch can be posted. Patches include all prior patch releases within the associated service pack level. The patches roll into the next official major or minor update, or service pack.
Before you can install a patch release, the most recent major or minor update, or service pack must be installed. For example, patch release 6.0(1p1) requires 6.0(1).
Note
Upgrading to a newer patch does not require you to uninstall the old patch. For example, you can upgrade from patch 6.0(1p1) to 6.0(1p2) without first uninstalling 6.0(1p1).
For More Information
For a table listing the types of files with examples of filenames and corresponding software releases, see IPS 6.x Software Release Examples.
Signature/Virus Updates and Signature Engine Updates
Figure 19-2 illustrates what each part of the IPS software file represents for signature/virus updates.
Figure 19-2 IPS Software File Name for Signature/Virus Updates,
Signature/Virus Updates
Executable file containing a set of rules designed to recognize malicious network activities. Signature updates are released independently from other software updates. Each time a major or minor update is released, you can install signature updates on the new version and the next oldest version for a period of at least six months. Signature updates are dependent on a required signature engine version. Because of this, a req designator lists the signature engine required to support a particular signature update.
A virus component for the signature updates is packaged with the signature update. Virus updates are generated by Trend Microsystems for use by the Cisco Intrusion Containment System (Cisco ICS). Once created for use by Cisco ICS, they are later be incorporated into standard Cisco signature updates.
Figure 19-3 illustrates what each part of the IPS software file represents for signature engine updates.
Figure 19-3 IPS Software File Name for Signature Engine Updates
Signature Engine Updates
Executable files containing binary code to support new signature updates. Signature engine files require a specific service pack, which is also identified by the req designator.
Recovery, Manufacturing, and System Image
Figure 19-4 illustrates what each part of the IPS software file represents for recovery and system image filenames.
Figure 19-4 IPS Software File Name for Recovery and System Image Filenames
Recovery and system images contain separate versions for the installer and the underlying application. The installer version contains a major and minor version field.
Installer Major Version
The major version is incremented by one of any major changes to the image installer, for example, switching from .tar to rpm or changing kernels.
Installer Minor Version
The minor version can be incremented by any one of the following:
•
Minor change to the installer, for example, a user prompt added.
•
Repackages require the installer minor version to be incremented by one if the image file must be repackaged to address a defect or problem with the installer.

Upgrading Cisco IPS Software to 6.2
The minimum required version for upgrading to 6.2 is 5.0(1) or later, which is available as a download from Cisco.com.
Note
Use IPS-AIM-K9-6.2-1-E3.pkg to upgrade AIM-IPS and IPS-NME-K9-6.2-1-E3 to upgrade NME-IPS. For all other supported sensors, use the IPS-K9-6.2-1-E3.pkg upgrade file.
If you configured Auto Update for your sensor, copy the Cisco IPS 6.2(1)E3 update files to the directory on the server that your sensor polls for updates. If you install an update on your sensor and the sensor is unusable after it reboots, you must reimage your sensor.
Caution 
If you are using automatic update with a mixture of AIM-IPS, NME-IPS, and other IPS appliances or modules, make sure you put both the 6.2(1)E3 upgrade file (IPS-K9-6.2-1-E3.pkg), the AIM-IPS upgrade file (IPS-AIM-K9-6.2-1-E3.pkg), and the NME-IPS upgrade file (IPS-NME-K9-6.2-1-E3) on the automatic update server so that AIM-IPS and NME-IPS can correctly detect which file needs to be automatically downloaded and installed. If you only put the 6.2(1)E3 upgrade file (IPS-K9-6.2-1-E3.pkg) on the server, AIM-IPS and NME-IPS will download and try to install the wrong file.
You can reimage your sensor in the following ways:
•
For all sensors, use the recover command.
•
For IPS-4240, IPS-4255, IPS-4260, and IPS 4270-20, use the ROMMON to restore the system image.
•
For AIM-IPS and NME-IPS, use the bootloader.
•
For IDSM-2, reimage the application partition from the maintenance partition.
Note
You cannot upgrade the IDSM (WS-X6381) to IPS 6.x. You must replace your IDSM (WS-X6381) with IDSM-2 (WS-SVC-IDSM2-K9), which supports version 6.2(1)E3.
•
For AIP-SSM and AIP-SSC-5, reimage from the adaptive security appliance using the hw-module module 1 recover configure/boot command.
Caution 
When you install the system image for your sensor, all accounts are removed and the default account and password are reset to
cisco.
