Note
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.

Cisco Security Intelligence Operations
The Cisco Security Intelligence Operations site on Cisco.com provides intelligence reports about current vulnerabilities and security threats. It also has reports on other security topics that help you protect your network and deploy your security systems to reduce organizational risk.
You should be aware of the most recent security threats so that you can most effectively secure and manage your network. Cisco Security Intelligence Operations contains the top ten intelligence reports listed by date, severity, urgency, and whether there is a new signature available to deal with the threat.
Cisco Security Intelligence Operations contains a Security News section that lists security articles of interest. There are related security tools and links.
You can access Cisco Security Intelligence Operations at this URL:
http://tools.cisco.com/security/center/home.x
Cisco Security Intelligence Operations is also a repository of information for individual signatures, including signature ID, type, structure, and description.
You can search for security alerts and signatures at this URL:
http://tools.cisco.com/security/center/search.x
New and Changed Information
Cisco IPS 6.0(5)E3 includes the following new features:
•
–
The signature date represents the date at which the signature was first created. The date is stored in the format YYYYMMDD. The signature type represents the category in which a specific signature falls. Signatures are broadly classified as vulnerability, exploit, anomaly, component, or other. The default is other.
–
Duplicate packet statistics are now added to the TCP Normalizer Stage Statistics section of the show statistics virtual sensor command output. Large numbers of duplicate packets being reported by the Normalizer can aid in the detection of sensor deployment and configuration problems. Duplicate packets are often seen in situations where a single virtual sensor is monitoring two or more networks, and is seeing a TCP connection crossing two or more of these networks. In this situation you can reconfigure the sensor to monitor each network using a different virtual sensor. If both networks must be monitored by a single virtual sensor, configure the virtual sensor with the inline-TCP-session-tracking-mode parameter set to either interface-and-vlan or vlan-only.
–
A new parameter to match a specific UDP length was added. This engine parameter is added in the Atomic IP Advanced and Atomic IP engine for l4-protocol UDP. The purpose of this parameter is to check if UDP total length falls within a specific range.

MySDN Decommissioned
Because MySDN has been decommissioned, the URL in older versions of IDM and IME is no longer functional. If you are using IPS 6.0 or later, we recommend that you upgrade your version of IDM and 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:
http://tools.cisco.com/security/center/search.x
For More Information
For information on MySDN (formerly known as NSDB) in IDM, refer to Configuring Signatures.
Before Upgrading to Cisco IPS 6.0(5)E3
This section describes the actions you should take before upgrading to Cisco IPS 6.0(5)E3. It contains the following topics:
•
•
Perform These Tasks
Before you upgrade your sensors to Cisco IPS 6.0(5)E3, make sure you perform the following tasks:
•
•
•
•
If you need to downgrade a signature update, you will know what version you had, and you can then apply the configuration you saved when you backed up your configuration.
•
•
In IPS 5.x, the read-only-community was set to public by default, and the read-write-community was set to private by default. In IPS 6.0(5)E3 these two options do not have default values. If you were not using SNMP gets and sets with IPS 5.x (for example, enable-set-get was set to false), there is no problem upgrading to IPS 6.0(5)E3. If you were using SNMP gets and sets with IPS 5.x (for example, enable-set-get was set to true), you must configure the read-only-community and read-write-community parameters to specific values or the IPS 6.0(5)E3 upgrade fails. You receive the following error message:
Error: execUpgradeSoftware : Notification Application "enable-set-get" value set to true, but "read-only-community" and/or "read-write-community" are set to null. Upgrade may not continue with null values in these fields.For More Information

Options
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 that 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 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
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 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
Service packs are 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
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 in to 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 5.0(1p1) requires 5.0(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/virus 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:

Note
•
sensor#upgrade scp://user@10.1.1.1/upgrades/IPS-K9-6.0-5-E3.pkg
Password: ********
Warning: Executing this command will apply a major version upgrade to the application partition. The system may be rebooted to complete the upgrade.
Continue with upgrade?: yes
Error: AnalysisEngine is not running. Please reset box and attempt upgrade again.If you receive this error, you must get Analysis Engine running before trying to upgrade again. This error is often caused by a defect in the currently running version. Try rebooting the sensor, and after reboot, run setup and remove the interfaces from the virtual sensor vs0. When it is not monitoring traffic, Analysis Engine usually stays up and running. You can upgrade to 6.0(5)E3 at this time. After the upgrade to IPS 6.0(5)E3, add the interfaces back to the virtual sensor vs0 using the setup command.
Or you can use the recovery CD (if your sensor has a CD-ROM) or the system image file to reimage directly to IPS 6.0(5)E3. You can reimage a 5.x sensor to 6.0(5)E3 because the reimage process does not check to see Analysis Engine is running.
Caution

Comparing Configurations
Compare your backed up and saved 5.1 configuration with the output of the show configuration command after upgrading to 6.0(5)E3 to verify that all the configuration has been properly converted.
Caution
For More Information
For the list of caveats for IPS 6.0(5)E3, see Caveats.
SSL Certificate
If necessary, import the new SSL certificate for the upgraded sensor in to each tool being used to monitor the sensor.
For More Information
For the CLI procedure for importing the SSL certificate, refer to Configuring TLS. For the IDM procedure, refer to Configuring Certificates.
Logging In to IDM
IDM is a web-based, Java Start application that enables you to configure and manage your sensor. The web server for IDM resides on the sensor. You can access it through Internet Explorer or Firefox web browsers.
To log in to IDM, follow these steps:
Step 1
https://sensor_ip_address
Note
Note
https://10.1.9.201, which you change to reflect your network environment when you initialize the sensor. When you change the web server port, you must specify the port in the URL address of your browser when you connect to IDM in the formathttps://sensor_ip_ address:port (for example,https://10.1.9.201:1040).

Licensing the Sensor
This section describes how to obtain a license key and how to license the sensor using the CLI or IDM. 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. 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 on the Licensing pane in IDM. Whenever you start IDM, 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 IDM but you cannot download signature updates.
When you enter the CLI, you are informed of your license status. For example, you receive the following message if there is no license installed:
***LICENSE NOTICE***There is no license key installed on the system.The system will continue to operate with the currently installedsignature set. A valid license must be obtained in order to applysignature updates. Please go to http://www.cisco.com/go/licenseto obtain a new license or install a license.You will continue to see this message until you install a license key.

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 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 purchased an ASA 5510 and then later wanted to add IPS and purchased 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.

Restrictions and Limitations
The following restrictions and limitations apply to Cisco IPS 6.0(5)E3 software and the products that run 6.0(5)E3:
•
•

•
•
•
•
•
•
AIM-IPS and the IOS firewall complement each other's abilities to create security zones in the network and inspect traffic in those zones. Because AIM IPS and the IOS firewall operate independently, sometimes they are unaware of the other's activities. In this situation, the IOS firewall is the best defense against a SYN flood attack.
•
•
•
•
•
•
This is true for any string that is used by CLI as an identifier, for example, names of time periods, inspect maps, server and URL lists, and interfaces.

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 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
The following menu appears:
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 IPS 4240 and 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.
To recover the password using the ROMMON CLI, follow these steps:
Step 1
Step 2
The boot code either pauses for 10 seconds or displays something similar to one of the following:
•

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 in to 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

Password Recovery for AIP SSM
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:
