Supported Servers
The following FTP servers are supported for IPS software updates:
•
•
•
•
•
The following HTTP/HTTPS servers are supported for IPS software updates:
•
•
ROMMON and TFTP
ROMMON uses TFTP to download an image and launch it. TFTP does not address network issues such as latency or error recovery. It does implement a limited packet integrity check so that packets arriving in sequence with the correct integrity value have an extremely low probability of error. But TFTP does not offer pipelining so the total transfer time is equal to the number of packets to be transferred times the network average RTT. Because of this limitation, we recommend that the TFTP server be located on the same LAN segment as the sensor. Any network with an RTT less than a 100 milliseconds should provide reliable delivery of the image. Be aware that some TFTP servers limit the maximum file size that can be transferred to ~32 MB.

New and Changed Information
Cisco IPS 7.0(7)E4 contains the following new and changed information:
•
•
•
–
Use this command to determine the load on the sensor instead of the CPU Usage information from the show statistics host command. The inspection load is a more accurate representation of the processing level of the sensor.
The Processing Load category in the show statistics virtual-sensor output has been renamed to Inspection Load Percentage and shows the same value seen in the show inspection load command.
The calculation of the inspection load has also been enhanced to provide a more accurate calculation of the sensor load at lower traffic levels.
–
–
–
Use caution when disabling, retiring, or changing the event action settings of a <Sig ID> TCP Normalizer signature for a sensor operating in IPS mode. The TCP Normalizer signature default values are essential for proper operation of the sensor.If the sensor is seeing duplicate packets, consider assigning the traffic to multiple virtual sensors. If you are having problems with asymmetric or out-of-order TCP packets, consider changing the normalizer mode from strict evasion protection to asymmetric mode protection. Contact Cisco TAC if you require further assistance.–

The Sensor and Jumbo Packet Frame Size
For IPS standalone appliances with 1 G and 10 G fixed or add-on interfaces, the maximum jumbo frame size is 9216 bytes.
Note
MySDN Decommissioned
Because MySDN has been decommissioned, the URL in older versions of the IDM and the IME is no longer functional. If you are using IPS 6.0 or later, we recommend that you upgrade your version of the IDM and the IME.
You can upgrade to the following versions to get the functioning MySDN URL:
•
•
If you are using version IPS 5.x, you must look up signature information manually at this URL:

Backing Up and Restoring the Configuration File Using a Remote Server
Note
Use the copy [/erase] source_url destination_url keyword command to copy the configuration file to a remote server. You can then restore the current configuration from the remote server. You are prompted to back up the current configuration first.
The following options apply:
•
This keyword only applies to the current-config; the backup-config is always overwritten. If this keyword is specified for destination current-config, the source configuration is applied to the system default configuration. If it is not specified for the destination current-config, the source configuration is merged with the current-config.

IPS Software Versioning
When you download IPS software images from Cisco.com, you should understand the versioning scheme so you know which files are base files, which are cumulative, and which are incremental.
Major Update
A major update contains new functionality or an architectural change in the product. For example, the Cisco IPS 7.0 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 7.0(1) requires 5.1(6) and later. With each major update there are corresponding system and recovery packages.
Note
Minor Update
A minor update is incremental to the major version. Minor updates are also base versions for service packs. The first minor update for 7.0 is 7.1. 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 Pack
A service pack is cumulative following a base version release (minor or major). Service packs are released in a train release format with several new features per train. Service packs contain all service pack fixes since the last base version (minor or major) and the new features and 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 7.0(7) is released, and E4 is the latest engine level, the service pack is released as 7.0(7)E4.
Patch Release
A patch release is 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 7.0(1p1) requires 7.0(1).
Note
Figure 1 illustrates what each part of the IPS software file represents for major and minor updates, service packs, and patch releases.
Figure 1 IPS Software File Name for Major and Minor Updates, Service Packs, and Patch Releases
Signature Update
A signature update is a package 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.
Figure 2 illustrates what each part of the IPS software file represents for signature updates.
Figure 2 IPS Software File Name for Signature Updates
Signature Engine Update
A signature engine update is an executable file containing binary code to support new signature updates. Signature engine files require a specific service pack, which is also identified by the req designator.
Figure 3 illustrates what each part of the IPS software file represents for signature engine updates.
Figure 3 IPS Software File Name for Signature Engine Updates
Recovery and System Image Files
Recovery and system image files contain separate versions for the installer and the underlying application. The installer version contains a major and minor version field. 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. The minor version can be incremented by any one of the following:

Installing and Uninstalling the Sensor License
This section describes how to obtain a license key, how to license the sensor using the CLI, the IDM, or the IME, and how to remove the license. It contains the following topics:
•
•
Understanding the License
Although the sensor functions without the license key, you must have a license key to obtain signature updates and use the global correlation features. To obtain a license key, you must have the following:
•
•
•
Trial license keys are also available. If you cannot get your sensor licensed because of problems with your contract, you can obtain a 60-day trial license that supports signature updates that require licensing.
You can obtain a license key from the Cisco.com licensing server, which is then delivered to the sensor. Or, you can update the license key from a license key provided in a local file. Go to http://www.cisco.com/go/license and click IPS Signature Subscription Service to apply for a license key.
You can view the status of the license key in these places:
•
•
•
•
Whenever you start the IDM, the IME, or the CLI, you are informed of your license status—whether you have a trial, invalid, or expired license key. With no license key, an invalid license key, or an expired license key, you can continue to use the IDM, the IME, and the CLI, but you cannot download signature updates.
If you already have a valid license on the sensor, you can click Download on the License pane to download a copy of your license key to the computer that the IDM or the IME is running on and save it to a local file. You can then replace a lost or corrupted license, or reinstall your license after you have reimaged the sensor.
Service Programs for IPS Products
You must have a Cisco Services for IPS service contract for any IPS product so that you can download a license key and obtain the latest IPS signature updates. If you have a direct relationship with Cisco Systems, contact your account manager or service account manager to purchase the Cisco Services for IPS service contract. If you do not have a direct relationship with Cisco Systems, you can purchase the service account from a one-tier or two-tier partner.
When you purchase the following IPS products you must also purchase a Cisco Services for IPS service contract:
•
•
•
•
•
•
•
When you purchase an ASA 5500 series adaptive security appliance product that does not contain IPS, you must purchase a SMARTnet contract.
Note
When you purchase an ASA 5500 series adaptive security appliance product that ships with the AIP SSM installed, or if you purchase it to add to your ASA 5500 series adaptive security appliance product, you must purchase the Cisco Services for IPS service contract.
Note
For example, if you purchase an ASA-5510 and then later want to add IPS and purchase an ASA-SSM-AIP-10-K9, you must now purchase the Cisco Services for IPS service contract. After you have the Cisco Services for IPS service contract, you must also have your product serial number to apply for the license key.
Caution
Obtaining and Installing the License Key
You can install the license key through the CLI, the IDM, the IME. This section describes how to obtain and install the license key, and contains the following topics:

The AIM IPS, the NME IPS, and the IOS firewall complement abilities of each other to create security zones in the network and inspect traffic in those zones. Because the AIM IPS, the NME IPS, and the IOS firewall operate independently, sometimes they are unaware of the activities of the other. In this situation, the IOS firewall is the best defense against a SYN flood attack.

Recovering the Password
For most IPS platforms, you can now recover the password on the sensor rather than using the service account or reimaging the sensor. This section describes how to recover the password for the various IPS platforms. It contains the following topics:

Understanding Password Recovery
Password recovery implementations vary according to IPS platform requirements. Password recovery is implemented only for the cisco administrative account and is enabled by default. The IPS administrator can then recover user passwords for other accounts using the CLI. The cisco user password reverts to cisco and must be changed after the next login.
Note
Table 4 lists the password recovery methods according to platform.
For More Information
For more information on when and how to disable password recovery, see Disabling Password Recovery.
Recovering the Appliance Password
This section describes the two ways to recover the password for appliances. It contains the following topics:
Using the GRUB Menu
For the 4200 series appliances, the password recovery is found in the GRUB menu, which appears during bootup. When the GRUB menu appears, press any key to pause the boot process.
Note
To recover the password on appliances, follow these steps:
Step 1
GNU GRUB version 0.94 (632K lower / 523264K upper memory)-------------------------------------------0: Cisco IPS1: Cisco IPS Recovery2: Cisco IPS Clear Password (cisco)-------------------------------------------Use the ^ and v keys to select which entry is highlighted.Press enter to boot the selected OS, 'e' to edit theCommands before booting, or 'c' for a command-line.Highlighted entry is 0:Step 2
Step 3
For More Information
For more information on connecting an appliance to a terminal server, refer to Connecting an Appliance to a Terminal Server.
Using ROMMON
For the IPS 4240 and the IPS 4255, you can use the ROMMON to recover the password. To access the ROMMON CLI, reboot the sensor from a terminal server or direct connection and interrupt the boot process.
Note
To recover the password using the ROMMON CLI, follow these steps:

Recovering the IDSM2 Password
To recover the password for the IDSM2, you must install a special password recovery image file. This installation only resets the password, all other configuration remains intact. The password recovery image is version-dependent and can be found on the Cisco Download Software site. For IPS 6.x, download WS-SVC-IDSM2-K9-a-6.0-password-recovery.bin.gz. For IPS 7.x, download WS-SVC-IDSM2-K9-a-7.0-password-recovery.bin.gz.
FTP is the only supported protocol for image installations, so make sure you put the password recovery image file on an FTP server that is accessible to the switch. You must have administrative access to the Cisco 6500 series switch to recover the password on the IDSM2.
During the password recovery image installation, the following message appears:
Upgrading will wipe out the contents on the hard disk.Do you want to proceed installing it [y|n]:This message is in error. Installing the password recovery image does not remove any configuration, it only resets the login account.
Once you have downloaded the password recovery image file, follow the instructions to install the system image file but substitute the password recovery image file for the system image file. The IDSM2 should reboot into the primary partition after installing the recovery image file. If it does not, enter the following command from the switch:
hw-module module module_number reset hdd:1

Recovering the AIP SSM Password
You can reset the password to the default (cisco) for the AIP SSM using the CLI or the ASDM. Resetting the password causes it to reboot. IPS services are not available during a reboot.
Note
Use the hw-module module slot_number password-reset command to reset the password to the default cisco. If the module in the specified slot has an IPS version that does not support password recovery, the following error message is displayed:
ERROR: the module in slot <n> does not support password recovery.Resetting the Password Using the CLI
To reset the password on the AIP SSM, follow these steps:
