Supported Platforms


Note All IPS platforms allow ten concurrent CLI sessions.



Note The AIM IPS and the NME IPS do not support the IPv6 features, because the routers in which they are installed do not send them IPv6 data. IPv6 inspection may work on the IDSM2, but we do not officially support it. There is no support for IPv6 on the management (command and control) interface. With ASA 8.2(1), the AIP SSM and the AIP SSC-5 support IPv6 features.


Cisco IPS 6.2(2)E4 is supported on the following platforms:

IPS 4240 Series Sensor Appliances

IPS 4255 Series Sensor Appliances

IPS 4260 Series Sensor Appliances

IPS 4270-20 Series Sensor Appliances

Intrusion Detection System Module (IDSM2) for Catalyst 6500 series switches

ASA-SSC-AIP-5 Series Cisco ASA Advanced Inspection and Prevention Security Services Cards (AIP SSC-5)

ASA-SSM-AIP-10 Series Cisco ASA Advanced Inspection and Prevention Security Service Modules (AIP SSM-10)

ASA-SSM-AIP-20 Series Cisco ASA Advanced Inspection and Prevention Security Service Modules (AIP SSM-20)

ASA-SSM-AIP-40 Series Cisco ASA Advanced Inspection and Prevention Security Service Modules (AIP SSM-40)

Intrusion Prevention System Advanced Integration Modules (AIM IPS)

Intrusion Prevention System Network Modules (NME IPS)

For More Information

For detailed information on each IPS appliance, refer to Installing Cisco Intrusion Prevention System Appliances and Modules 6.2.

Supported Servers

The following FTP servers are supported for IPS software updates:

WU-FTPD 2.6.2 (Linux)

Solaris 2.8

Sambar 6.0 (Windows 2000)

Serv-U 5.0 (Windows 2000)

MS IIS 5.0 (Windows 2000)

The following HTTP/HTTPS servers are supported for IPS software updates:

CMS - Apache Server (Tomcat)

CMS - Apache Server (JRun)

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.

For More Information

For the procedure for downloading IPS software updates from Cisco.com, see Obtaining Software on Cisco.com.

For the procedure for configuring automatic upgrades, for the CLI refer to Configuring Automatic Upgrades, for IDM refer to Configuring Automatic Update, and for IME refer to Configuring Automatic Update.

IPS Management and Event Viewers

Use the following tools for configuring Cisco IPS 6.2(2)E4 sensors:

Cisco IDM 7.0(3)

Cisco IME 6.2 and 7.0

IPS CLI 6.2

ASDM 5.2 and later

CSM 3.3 and later


Note We recommend that ASDM users upgrade to ASDM 6.3 or later. The Java VM upper memory limit of ASDM 6.3 has been increased. Older versions of ASDM may not have enough available memory for IDM and 7.0(3) to function properly.


Use the following tools for monitoring Cisco IPS  6.2(2)E4 sensors:

Cisco IME 6.2 and 7.0


Note The current versions of IME work with the E4 engine upgrade, but do not correctly display the new values allowed in the Retired signature field. An updated version of IME is in progress and will be released shortly after the E4 engine update. The current versions of IME also do not have the expanded memory capability for the Java VM and may cause problems when you tune signatures.


CSM 4.0


Note You may need to configure viewers that are already configured to monitor the Cisco IPS 6.1 sensors to accept a new SSL certificate for the Cisco IPS 6.2(2)E4 sensors.


New and Changed Information

Cisco IPS 6.2(2)E4 includes the new E4 signature engine.

The E4 signature engine update includes signature update 480, which is not available for separate download. The E4 signature engine update contains the following new features:

Port-agnostic HTTP inspection

The IPS now allows inspection of HTTP on any port. The Service HTTP engine now contains a parameter (ALLPORTS) that aids you in configuring inspection of HTTP on any port.

Meta engine enhancements

The purpose of the Meta engine is to detect a specified payload from an attacker and a corresponding payload from the victim. It is also used to inspect streams at different offsets. The Meta engine supports the AND and OR logical operators. ANDNOT capability has been added to the Meta engine. This clause is a negative clause used to complement the existing positive clause-based signatures. The previous signature format had the following form:

IF (A and B and C) then Alarm; alternatively, IF (A or B or C) then Alarm is also 
supported; where A, B, and C are meta component signatures.
 
   

The addition of the negative clause allows for the following logic:

IF (A and/or B) AND NOT (C and/or D) then Alarm.
 
   

The (C and/or D) is the negative clause and is satisfied if (C and D) [alternatively (C or D)] do not occur before the Meta Reset Interval time expires.

A component of the positive clause must occur before the negative clause(s) to establish the Meta tracking state. The Meta engine cannot track the lack of past behavior.The state of the negative clause is evaluated when the Meta Reset Interval time expires.

Signature load thresholding

The retired attribute of a signature has been changed to support the variable loading of signatures based on platform. A signature can be retired or active with additional values that include low memory retired (low-mem-retired) and medium memory retired (medium-mem-retired). Low memory retired platforms have less that 1 GB of maximum sensor memory, and include the following sensors: IPS 4215, AIP SSC-5, AIM IPS, NME IPS, AIP SSM-10, AIP SSM-20, and AIP SSM-40. Medium memory retired platforms have at least 1 GB and less than 4 GB of maximum sensor memory, and include the following sensors: IDSM2, IPS 4240, IPS 4255, IPS 4260, and IPS 4270-20. Platforms with 4GB and higher maximum sensor memory are considered high memory platforms. As the signatures are loaded, the value of retired is evaluated based on the platform loading the signatures.

The Retired parameter has the following new options:

True—Retired on all platforms.

Medium Memory Retired—Signature is retired on all medium and low memory platforms.

Low Memory Retired—Signature is retired on low memory platforms.

False—Signature is not retired on any platform.

Three new String engines that provide support for future IPS hardware and software releases—String ICMP XL, String TCP XL, and String UDP XL.

These signature engines provide optimized operation for new hardware and are not operational in the E4 update. If you try to use them, you will receive an error message.

Signature definition support for three new IOS IPS engines—Service FTP V2, Service HTTP V2, and Service SMTP V1.

These signature engines provide a protocol decode engine tuned for IOS IPS. If you try to use these engines, you receive an error message.

The Service DNS engine has been enhanced to provide domain name matching.

A new parameter, FQDN (Fully Qualified Domain Name) has been added in the Specify Block parameter to enable this capability. FQDN matching uses a case insensitive substring matching algorithm instead of regular expressions. Because it matches on substrings, you must take care in constructing the FQDN parameter.

For example, an FQDN parameter of "cisco.com" will match any domain name lookup for computers in the "cisco.com" domain, but it will also match the "sanfrancisco.com" domain as well. Including the "." as in ".cisco.com" will eliminate the obvious false positive, but remember that the shorter the FQDN string, the higher the likelihood of a false positive. You can write a simple signature as a custom signature in the Service DNS engine by setting the protocol to UDP, setting FQDN to yes, and then setting the FQDN string to cisco.com.


Caution The FQDN match is performed on DNS queries for "A records" (DNS Type 1 query) only. DNS responses are not matched, nor are other types of queries, such as MX records.

The P2P inspection engine has been enhanced to detect the Share P2P software popular in Japan.

For More Information

For detailed information on the Service HTTP engine, refer to Service HTTP Engine.

For detailed information on the Meta engine, refer to Meta Engine.

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:

IDM 7.0.3

IME 7.0.3

IPS 7.0(4), which contains IDM 7.0.4

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 detailed information on MySDN, for IDM refer to MySDN and for IME refer to MySDN.

Cisco IPS Device Manager

A new version of IDM is bundled with the E4 engine update, IDM 7.0(3). We have modified IDM to correctly display and edit the additional values allowed in the Retired parameter field of a signature. We have also modified IDM and its associated ASDM Launcher application to increase the upper memory limit that Java VM uses. With this change you can display and tune more signatures in IDM.


Note We recommend that ASDM users upgrade to ASDM 6.3 or later. The Java VM upper memory limit of ASDM 6.3 has been increased. Older versions of ASDM may not have enough available memory for IDM7.0(3) to function properly.



Note After upgrading to the E4 signature engine, disconnect and restart any open IDM sessions to make sure that your system downloads and uses the latest IDM application from the sensor.


For More Information

For more information about the new values allowed in the Retired parameter for a signature, see New and Changed Information.

IPv6, Switches, and Lack of VACL Capture

VACLs on Catalyst switches do not have IPv6 support. The most common method for copying traffic to a sensor configured in Promiscuous mode is to use VACL capture. If you want to have IPv6 support, you can use SPAN ports.

However, you can only configure up to two monitor sessions on a switch unless you use the following configuration:

Monitor session

Multiple trunks to one or more sensors

Restrict per trunk port which VLANs are allowed to perform monitoring of many VLANs to more than two different sensors or virtual sensors within one IPS

The following configuration uses one SPAN session to send all of the traffic on any of the specified VLANs to all of the specified ports. Each port configuration only allows a particular VLAN or VLANs to pass. Thus you can send data from different VLANs to different sensors or virtual sensors all with one SPAN configuration line:

clear trunk 4/1-4 1-4094
set trunk 4/1 on dot1q 930
set trunk 4/2 on dot1q 932
set trunk 4/3 on dot1q 960
set trunk 4/4 on dot1q 962
set span 930, 932, 960, 962 4/1-4 both
 
   

Note The SPAN/Monitor configuration is valuable when you want to assign different IPS policies per VLAN or when you have more bandwidth to monitor than one interface can handle.


For More Information

For more information on configuring SPAN/monitor on switches, refer to the following sections in Catalyst 6500 Series Software Configuration Guide, 8.7:

Backing Up and Restoring the Configuration File Using a Remote Server


Note We recommend copying the current configuration file to a remote server before upgrading.


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.

Options

The following options apply:

/erase—Erases the destination file before copying.

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.

source_url—The location of the source file to be copied. It can be a URL or keyword.

destination_url—The location of the destination file to be copied. It can be a URL or a keyword.

current-config—The current running configuration. The configuration becomes persistent as the commands are entered.

backup-config—The storage location for the configuration backup.

The exact format of the source and destination URLs varies according to the file. Here are the valid types:

ftp:—Source or destination URL for an FTP network server. The syntax for this prefix is:

ftp:[//[username@] location]/relativeDirectory]/filename

ftp:[//[username@]location]//absoluteDirectory]/filename

scp:—Source or destination URL for the SCP network server. The syntax for this prefix is:

scp:[//[username@] location]/relativeDirectory]/filename

scp:[//[username@] location]//absoluteDirectory]/filename


Note If you use FTP or SCP protocol, you are prompted for a password. If you use SCP protocol, you must also add the remote host to the SSH known hosts list.


http:—Source URL for the web server. The syntax for this prefix is:

http:[[/[username@]location]/directory]/filename

https:—Source URL for the web server. The syntax for this prefix is:

https:[[/[username@]location]/directory]/filename


Note HTTP and HTTPS prompt for a password if a username is required to access the website. If you use HTTPS protocol, the remote host must be a TLS trusted host.



Caution Copying a configuration file from another sensor may result in errors if the sensing interfaces and virtual sensors are not configured the same.

Backing Up the Current Configuration to a Remote Server

To back up your current configuration to a remote server, follow these steps:


Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Back up the current configuration to the remote server.

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 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

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 Pack

A service pack is 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 6.2(2) is released, and E4 is the latest engine level, the service pack is released as 6.2(2)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 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).


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:

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 to Cisco IPS 6.2(2)E4

This section provides information on upgrading to Cisco IPS 6.2(2)E4, and contains the following topics:

Upgrade Notes and Caveats

Upgrading to 6.2(2)E4

Upgrade Notes and Caveats

The following upgrade notes and caveats apply to upgrading your sensor to IPS 6.2(2)E4:

You must have a valid Cisco Service for IPS Maintenance contract per sensor to receive and use software upgrades from Cisco.com.

Minimum required versions:

Appliances must be running 5.0(1) or later but less than 7.0(1).

The AIM IPS must be running 6.0(4) or later but less than 7.0(1).

The NME IPS must be running 6.1(1) or later but less than 7.0(1).

The AIP SSC-5 must be running version 6.2(1).


Note Use IPS-AIM-K9-6.2-2-E4.pkg to upgrade the AIM IPS, IPS-NME-K9-6.2-2-E4 to upgrade the NME IPS, and IPS-SSC_5-K9-6.2-2-E4.pkg to upgrade the AIP SSC-5. For all other supported sensors, use the IPS-K9-6.2-2-E4.pkg upgrade file.


You cannot upgrade 6.2(2)E3 to 6.2(2)E4 using the IPS-K9-6.2-2-E4.pkg upgrade file. You must use the engine update file, IPS-engine-E4-req-6.2-2.pkg.

The sensor goes in to the configured bypass mode during the update as the inspection software is stopped, replaced, and restarted. The sensor automatically exits bypass mode and resumes traffic inspection upon completion of the new inspection software startup and configuration. The engine update procedure normally installs the update without rebooting the sensor. However, if an error is detected during the update, the installation process attempts to reboot the sensor in order to leave the sensor in an operational state.

After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.

Using automatic update:

If you configured automatic update for your sensor, copy the 6.2(2)E4 update files to the directory on the server that your sensor polls for updates.

If you are using automatic update with a mixture of IPS appliances and modules (AIM IPS, AIP SSC-5, or NME IPS), make sure you put all of the 6.2(2)E4 upgrade files on the automatic update server so the modules can correctly detect which file needs to be automatically downloaded and installed. If you only put the 6.2(2)E4upgrade file (IPS-K9-6.2-2-E4.pkg) on the server, the modules will download and try to install the wrong file.

When you upgrade the AIM IPS or the NME IPS using automatic update, you must disable heartbeat reset on the router before placing the upgrade file on your automatic update server. After the module has been automatically updated, you can reenable heartbeat reset. If you do not disable heartbeat reset, the upgrade can fail and leave the module in an unknown state, which can require a system reimage to recover.

Using manual update:

When you upgrade the AIM IPS or the NME IPS using manual upgrade, you must disable heartbeat reset on the router before installing the upgrade. You can reenable heartbeat reset after you complete the upgrade. If you do not disable heartbeat reset, the upgrade can fail and leave the AIM IPS or the NME IPS in an unknown state, which can require a system reimage to recover.

If you install an update on your sensor and the sensor is unusable after it reboots, you must reimage your sensor. 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 the AIM IPS and the NME IPS, use the bootloader.

For the IDSM2, reimage the application partition from the maintenance partition.

For the AIP SSM and the 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.

For More Information

For the procedures for reimaging sensors, refer to Upgrading, Downgrading, and Installing System Images.

For the procedure for disabling heartbeat reset, for the AIM IPS refer to Enabling and Disabling Heartbeat Reset, and for the NME IPS refer to Enabling and Disabling Heartbeat Reset.

For more information on Cisco service contracts, see Service Programs for IPS Products.

For the procedure for configuring automatic upgrade, refer to Configuring Automatic Upgrades.

Upgrading to 6.2(2)E4


Caution You must log in to Cisco.com using an account with cryptographic privileges to download software. The first time you download software on Cisco.com, you receive instructions for setting up an account with cryptographic privileges.


Caution Do not change the filename. You must preserve the original filename for the sensor to accept the update.

To upgrade the sensor, follow these steps:


Step 1 Download the appropriate file to an FTP, SCP, HTTP, or HTTPS server that is accessible from your sensor.


Note Use IPS-AIM-K9-6.2-2-E4.pkg to upgrade the AIM IPS, IPS-NME-K9-6.2-2-E4 to upgrade the NME IPS, and IPS-SSC_5-K9-6.2-2-E4.pkg to upgrade the AIP SSC-5. For all other supported sensors, use the IPS-K9-6.2-2-E4.pkg upgrade file.



Caution You must upgrade IPS 6.2(2)E3 to IPS 6.2(2)E4 using the engine upgrade file (IPS-engine-E4-req-6.2-2.pkg) because you are upgrading the engine only. You cannot use the IPS-K9-6.2-2-E4.pkg upgrade file to upgrade from 6.2(2)E3 to 6.2(2)E4. Engine updates may or may not cause the sensor to reboot.

Step 2 Log in to the CLI using an account with administrator privileges.

Step 3 Enter configuration mode.
sensor# configure terminal
 
   

Step 4 Upgrade the sensor.

sensor(config)# upgrade url/IPS-K9-6.2-2-E4.pkg
 
   

The URL points to where the update file is located, for example, to retrieve the update using FTP, enter the following:

sensor(config)# upgrade ftp://username@ip_address//directory/IPS-K9-6.2-2-E4.pkg
 
   
Step 5 Enter the password when prompted.
Enter password: ********
 
   

Step 6 Enter yes to complete the upgrade.


Note Major updates, minor updates, and service packs may force a restart of the IPS processes or even force a reboot of the sensor to complete installation.



Note The operating system is reimaged and all files that have been placed on the sensor through the service account are removed.


Step 7 Verify your new sensor version:

For More Information

For the procedures for configuring TLS/SSL, for the CLI refer to Configuring TLS, for IDM refer to Configuring Trusted Hosts, and for IME refer to Configuring Trusted Hosts.

Logging In to IDM

IDM is a web-based, Java Web 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.


Note IDM is already installed on the sensor.


To log in to IDM, follow these steps:


Step 1 Open a web browser and enter the sensor IP address. A Security Alert dialog box appears.

https://sensor_ip_address
 
   

Note The default IP address is 192.168.1.2/24,192.168.1.1, 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 format https://sensor_ip_address:port (for example, https://10.1.9.201:1040).


Step 2 Click Yes to accept the security certificate. The Cisco IPS Device Manager Version 6.2 window appears.

Step 3 To launch IDM, click Run IDM. The JAVA loading message box appears, and then the Warning - Security dialog box appears.

Step 4 To verify the security certificate, check the Always trust content from this publisher check box, and click Yes. The JAVA Web Start progress dialog box appears, and then the IDM on ip_address dialog box appears.

Step 5 To create a shortcut for IDM, click Yes. The Cisco IDM Launcher dialog box appears.


Note You must have JRE 1.5 (JAVA 5) installed to create shortcuts for IDM. If you have JRE 1.6 (JAVA 6) installed, the shortcut is created automatically.


Step 6 To authenticate IDM, enter your username and password, and click OK. IDM begins to load. If you change panes from Home to Configuration or Monitoring before IDM has complete initialization, a Status dialog box appears with the following message:

Please wait while IDM is loading the current configuration from the sensor.
 
   

The main window of IDM appears.


Note Both the default username and password are cisco. You were prompted to change the password during sensor initialization.



Note If you created a shortcut, you can launch IDM by double-clicking the IDM shortcut icon. You can also close the Cisco IPS Device Manager Version 6.2 window. After you launch IDM, is it not necessary for this window to remain open.



For More Information

For more information about security and IDM, refer to IDM and Certificates.

For the procedure for initializing the sensor, refer to Initializing the Sensor.

Licensing the Sensor

This section describes how to obtain a license key and how to license the sensor using the CLI, IDM, or IME. It contains the following topics:

Understanding the License

Service Programs for IPS Products

Obtaining and Installing the License Key

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:

Cisco Service for IPS service contract—Contact your reseller, Cisco service or product sales to purchase a contract.

Your IPS device serial number—To find the IPS device serial number in IDM or IME, for IDM choose Configuration > Sensor Management > Licensing, and for IME choose Configuration > sensor_name > Sensor Management > Licensing, or in the CLI use the show version command.

Valid Cisco.com username and password

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:

IDM Home window Licensing section on the Health tab

IDM Licensing pane (Configuration > Licensing)

IME Home page in the Device Details section on the Licensing tab

License Notice at CLI login

Whenever you start IDM, 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 IDM, 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 IDM or 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.

For More Information

For more information on Cisco service contracts, see Service Programs for IPS Products.

For the procedure for obtaining and installing the license, see Obtaining and Installing the 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:

IPS 4240

IPS 4255

IPS 4260

IPS 4270-20

AIM IPS

IDSM2

NME IPS

When you purchase an ASA 5500 series adaptive security appliance product that does not contain IPS, you must purchase a SMARTnet contract.


Note SMARTnet provides operating system updates, access to Cisco.com, access to TAC, and hardware replacement NBD on site.


When you purchase an ASA 5500 series adaptive security appliance product that ships with the AIP SSM or AIP SSC-5 installed, or if you purchase them to add to your ASA 5500 series adaptive security appliance product, you must purchase the Cisco Services for IPS service contract.


Note Cisco Services for IPS provides IPS signature updates, operating system updates, access to Cisco.com, access to TAC, and hardware replacement NBD on site.


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 If you ever send your product for RMA, the serial number changes. You must then get a new license key for the new serial number.

For More Information

For the procedure for obtaining and installing the license, see Obtaining and Installing the License Key.

Obtaining and Installing the License Key

You can install the license key through the CLI, IDM, or IME. This section describes how to obtain and install the license key, and contains the following topics:

Using the CLI

Use the copy source-url license_file_name license-key command to copy the license key to your sensor.

The following options apply:

source-url—The location of the source file to be copied. It can be a URL or keyword.

destination-url—The location of the destination file to be copied. It can be a URL or a keyword.

license-key—The subscription license file.

license_file_name—The name of the license file you receive.


Note You cannot install an older license key over a newer license key.


The exact format of the source and destination URLs varies according to the file. Here are the valid types:

ftp:—Source or destination URL for an FTP network server. The syntax for this prefix is:

ftp:[//[username@] location]/relativeDirectory]/filename

ftp:[//[username@]location]//absoluteDirectory]/filename

scp:—Source or destination URL for the SCP network server. The syntax for this prefix is:

scp:[//[username@] location]/relativeDirectory]/filename

scp:[//[username@] location]//absoluteDirectory]/filename


Note If you use FTP or SCP protocol, you are prompted for a password. If you use SCP protocol, you must add the remote host to the SSH known hosts list.


http:—Source URL for the web server. The syntax for this prefix is:

http:[[/[username@]location]/directory]/filename

https:—Source URL for the web server. The syntax for this prefix is:

https:[[/[username@]location]/directory]/filename


Note If you use HTTPS protocol, the remote host must be a TLS trusted host.

Installing or Upgrading Cisco IME and Migrating Data Into IME

This section describes how to install and upgrade IME, and how to migrate data from IEV or a previous version of IME.


Note You can use IME 6.2 or 7.0 to monitor 6.2(1)E3 sensors.


Cisco IEV, Cisco IOS IPS, and CSM

If you have a version of Cisco IPS Event Viewer installed, the Install wizard prompts you to remove it before installing IME.

IME event monitoring is also supported in IOS-IPS versions that support the Cisco IPS 5.x/6.x signature format. We recommend IOS-IPS 12.4(15)T4 if you intend to use IME to monitor an IOS IPS device. Some of the new IME functionality including health monitoring is not supported.


Caution Do not install IME on top of existing installations of CSM. You must uninstall CSM before installing IME. Do not install CSM on top of existing installations of IME.

Installation Notes and Caveats

Observe the following when installing or upgrading IME:

You can install IME over all versions of IME but not over IEV. All alert database and user settings are preserved.

IME detects previous versions of IEV and prompts you to manually remove the older version before installing IME or to install IME on another system. The installation program then stops.

Make sure you close any open instances of IME before upgrading to a new version of IME.

Disable any anti-virus or host-based intrusion detection software before beginning the installation, and close any open applications. The installer spawns a command shell application that may trigger your host-based detection software, which causes the installation to fail.

You must be administrator to install IME.

IME coexists with other instances of the MySQL database. If you have a MySQL database installed on your system, you do NOT have to uninstall it before installing IME.

Installing or Upgrading IME

To install IME, follow these steps:


Step 1 From the Download Software site on Cisco.com, download the IME executable file to your computer, or start IDM in a browser window, and under Cisco IPS Manager Express, click download to install the IME executable file. IME-7.0.4.exe is an example of what the IME executable file might look like.

Step 2 Double-click the executable file. The Cisco IPS Manager Express - InstallShield Wizard appears. You receive a warning if you have a previous version of Cisco IPS Event Viewer installed. Acknowledge the warning, and exit installation. Remove the older version of IEV, and then continue IME installation.

Step 3 Click Next to start IME installation.

Step 4 Accept the license agreement and click Next.

Step 5 Click Next to choose the destination folder, click Install to install IME, and then click Finish to exit the wizard. The Cisco IME and Cisco IME Demo icons are now on your desktop.


Note The first time you start IME, you are prompted to set up a password.



Migrating IEV Data

To migrate IEV 5.x events to IME, you must exit the installation and manually export the old events by using the IEV 5.x export function to move the data to local files. After installing IME, you can import these files to the new IME system.


Note IME does not support import and migration functions for IEV 4.x.


To export event data from IEV 5.x to a local file:


Step 1 From IEV 5.x, choose File > Database Administration > Export Database Tables.

Step 2 Enter the file name and select the table(s).

Step 3 Click OK. The events in the selected table(s) are exported to the specified local file.


Importing IEV Event Data In to IME

To import event data in to IME, follow these steps:


Step 1 From IME, choose File > Import.

Step 2 Select the file exported from IEV 5.x and click Open. The contents of the selected file are imported in to IME.


For More Information

For more information about Cisco IME, refer to Installing and Using Cisco Intrusion Prevention System Manager Express 6.2 or Installing and Using cisco Intrusion Prevention System Manager Express 7.0.

Restrictions and Limitations

The following restrictions and limitations apply to Cisco IPS 6.2(2)E4 software and the products that run 6.2(2)E4:

For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no password cisco command, but you cannot remove it. To use the no password cisco command, there must be another administrator account on the sensor. Removing the cisco account through the service account is not supported. If you remove the cisco account through the service account, the sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system image.

The AIP SSC-5 does not support virtualization, unretiring default retired signatures, creating custom signatures, adding signatures, cloning signatures, or anomaly detection.

The AIP SSC-5 can take up to 20 minutes to come online when it reboots after the installation of a new system image. You must let the process complete before you can make configuration changes to the AIP SSC-5. If you try to modify and save configuration changes before the process is complete, you receive an error message.

Anomaly detection does not support IPv6 traffic; only IPv4 traffic is directed to the anomaly detection processor.

ICMP signature engines do not support ICMPv6, they are IPv4-specific, for example, the Traffic ICMP signature engine. ICMPv6 is covered by the Atomic IP Advanced signature engine.

Rate limiting and blocking are not supported for IPv6 traffic. If a signature is configured with a block or rate limit event action and is triggered by IPv6 traffic, an alert is generated but the action is not carried out.

IPv6 does not support the following event actions: Request Block Host, Request Block Connection, or Request Rate Limit.

CSM and MARS do not support IPv6.

The AIM IPS and the NME IPS do not support the IPv6 features, because the routers in which they are installed do not send them IPv6 data. IPv6 inspection may work on the IDSM2, but we do not officially support it. There is no support for IPv6 on the management (command and control) interface. With ASA 8.2(1), the AIP SSM and the AIP SSC-5 support IPv6 features.

VACLs on Catalyst switches do not have IPv6 support. The most common method for copying traffic to a sensor configured in Promiscuous mode is to use VACL capture. If you want to have IPv6 support, you can use SPAN ports.

The AIM IPS and the NME IPS do not support virtualization.

When you reload the router, the AIM IPS and the NME IPS also reload. To ensure that there is no loss of data on the AIM IPS or the NME IPS, make sure you shut down the module using the shutdown command before you use the reload command to reboot the router.

Do not deploy IOS IPS and the AIM IPS and the NME IPS at the same time.

When the AIM IPS and the NME IPS are used with an IOS firewall, make sure SYN flood prevention is done by the IOS firewall.

The AIM IPS and 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 and 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.

Cisco access routers only support one IDS/IPS per router.

On IPS sensors with multiple processors (for example, the IPS 4260 and IPS 4270-20), packets may be captured out of order in the IP logs and by the packet command. Because the packets are not processed using a single processor, the packets can become out of sync when received from multiple processors.

An IPS appliance can support both promiscuous and inline monitoring at the same time; however you must configure each physical interface in either Promiscuous or Inline mode. The sensor must contain at least two physical sensing interfaces to perform both promiscuous and inline monitoring. The exceptions to this are the AIP SSM-10, the AIP SSM-20, and the AIP SSM-40. The AIP SSM can support both promiscuous and inline monitoring on its single physical back plane interface inside the adaptive security appliance. The configuration on the main adaptive security appliance can be used to designate which packets/connections should be monitored by the AIP SSM as either promiscuous or inline.

When deploying an IPS sensor monitoring two sides of a network device that does TCP sequence number randomization, we recommend using a virtual senor for each side of the device.

After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.

IDM does not support any non-English characters, such as the German umlaut or any other special language characters. If you enter such characters as a part of an object name through IDM, they are turned into something unrecognizable and you will not be able to delete or edit the resulting object through IDM or the CLI.

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.

You can only install eight IDSM2s per switch chassis.

When SensorApp is reconfigured, there is a short period when SensorApp cannot respond to any queries. Wait a few minutes after reconfiguration is complete before querying SensorApp for additional information.

IDM and IME launch MySDN from the last browser window you opened, which is the default setting for Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet Options, and then click the Advanced tab. Scroll down and uncheck the Reuse windows for launching shortcuts check box.

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

Recovering the Appliance Password

Recovering the IDSM2 Password

Password Recovery for the AIP SSC-5

Password Recovery for the AIP SSM

Recovering the AIM IPS Password

Recovering the NME IPS Password

Disabling Password Recovery

Verifying the State of Password Recovery

Troubleshooting Password Recovery

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 Administrators may need to disable the password recovery feature for security reasons.


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

Using ROMMON

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 You must have a terminal server or direct serial connection to the appliance to use the GRUB menu to recover the password.


To recover the password on appliances, follow these steps:


Step 1 Reboot the appliance.

The following menu appears:

GNU GRUB version 0.94 (632K lower / 523264K upper memory)
-------------------------------------------
0: Cisco IPS
1: Cisco IPS Recovery
2: 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 the
    Commands before booting, or 'c' for a command-line.
 
   
    Highlighted entry is 0:
 
   

Step 2 Press any key to pause the boot process.

Step 3 Choose 2: Cisco IPS Clear Password (cisco).

The password is reset to cisco. You can change the password the next time you log into the CLI.


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.

To recover the password using the ROMMON CLI, follow these steps:


Step 1 Reboot the appliance.

Step 2 To interrupt the boot process, press ESC or Control-R (terminal server) or send a BREAK command (direct connection).

The boot code either pauses for 10 seconds or displays something similar to one of the following:

Evaluating boot options

Use BREAK or ESC to interrupt boot

Step 3 Enter the following commands to reset the password:

confreg 0x7
boot
 
   

Sample ROMMON session:

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

Note The password is reset to cisco. Log in to the CLI with username cisco and password cisco. You can then change the password.


For More Information

For the procedures for reimaging the IDSM2, refer to Installing the IDSM2 System Image.

For more information on downloading Cisco IPS software, see Obtaining Software on Cisco.com.

Password Recovery for the AIP SSC-5

You can reset the password to the default (cisco) for the AIP SSC-5 using the CLI or the ASDM. Resetting the password causes it to reboot. IPS services are not available during a reboot.


Note To reset the password, you must have ASA 8.2(1) or later.


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.

Disabling Password Recovery


Caution If you try to recover the password on a sensor on which password recovery is disabled, the process proceeds with no errors or warnings; however, the password is not reset. If you cannot log in to the sensor because you have forgotten the password, and password recovery is set to disabled, you must reimage your sensor.

Password recovery is enabled by default. You can disable password recovery through the CLI or IDM.

Disabling Password Recovery Using the CLI

To disable password recovery in the CLI, follow these steps:


Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter global configuration mode.

sensor# configure terminal
 
   

Step 3 Enter host mode.

sensor(config)# service host
 
   

Step 4 Disable password recovery.

sensor(config-hos)# password-recovery disallowed
 
   

Disabling Password Recovery Using IDM

To disable password recovery in IDM, follow these steps:


Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Choose Configuration > Sensor Setup > Network. The Network pane appears.

Step 3 To disable password recovery, uncheck the Allow Password Recovery check box.


For More Information

If you are not certain about whether password recovery is enabled or disabled, see Verifying the State of Password Recovery.

For more information on reimaging sensors, refer to Upgrading, Downgrading, and Installing System Images.

Verifying the State of Password Recovery

Use the show settings | include password command to verify whether password recovery is enabled. To verify whether password recovery is enabled, follow these steps:


Step 1 Log in to the CLI.

Step 2 Enter service host submode.

sensor# configure terminal
sensor (config)# service host
sensor (config-hos)# 
 
   

Step 3 Verify the state of password recovery by using the include keyword to show settings in a filtered output.

sensor(config-hos)# show settings | include password
   password-recovery: allowed <defaulted>
sensor(config-hos)#
 
   

Troubleshooting Password Recovery

To troubleshoot password recovery, pay attention to the following:

You cannot determine whether password recovery has been disabled in the sensor configuration from the ROMMON prompt, GRUB menu, switch CLI, or router CLI. If password recovery is attempted, it always appears to succeed. If it has been disabled, the password is not reset to cisco. The only option is to reimage the sensor.

You can disable password recovery in the host configuration. For the platforms that use external mechanisms, such as the AIM IPS and the NME IPS bootloader, ROMMON, and the maintenance partition for the IDSM2, although you can run commands to clear the password, if password recovery is disabled in the IPS, the IPS detects that password recovery is not allowed and rejects the external request.

To check the state of password recovery, use the show settings | include password command.

When performing password recovery on the IDSM2, you see the following message: Upgrading will wipe out the contents on the storage media. You can ignore this message. Only the password is reset when you use the specified password recovery image.

For More Information

For more information on reimaging sensors, refer to Upgrading, Downgrading, and Installing System Images.

For the procedure for disabling password recovery, see Disabling Password Recovery.

For the procedure for verifying the state of password recovery, see Verifying the State of Password Recovery.
