Caution The BIOS on Cisco IPS sensors is specific to 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 IPS sensors voids the warranty.

IPS File List


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 router in which they are installed does 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.

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

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.

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 URL for an FTP network server. The syntax for this prefix is:

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

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


Note You are prompted for a password.


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

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

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


Note You are prompted for a password. 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


Note The directory specification should be an absolute path to the desired file.


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

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


Note The directory specification should be an absolute path to the desired file. 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.

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 The 7.0(1) major update is used to upgrade 5.1(6) and later sensors to 7.0(1) If you are reinstalling 7.0(1) on a sensor that already has 7.0(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 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(9) is released, and E4 is the latest engine level, the service pack is released as 7.0(9)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 Upgrading to a newer patch does not require you to uninstall the old patch. For example, you can upgrade from patch 7.0(1p1) to 7.0(1p2) without first uninstalling 7.0(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

This section provides information on upgrading to Cisco IPS 7.0(9)E4, and contains the following topics:

Upgrade Notes and Caveats

Upgrading to IPS 7.0(9)E4

CSM Update Instructions

Upgrade Notes and Caveats

The following upgrade notes and caveats apply to upgrading your sensor to IPS 7.0(9)E4:

IPS 7.0(9)E4 supports the IDSM2, AIM IPS, and NME IPS.

IPS 7.0(9)E4 does not support the IPS 4240, IPS 4255, IPS 4260, or IPS 4270-20. We recommend that you upgrade from 7.0(x)E4 to 7.1(7)E4.

The minimum required version for upgrading to IPS 7.0(9)E4 is IPS 5.1(6)E3 or later.

You must be logged on to Cisco.com using an account with cryptographic privileges to access the download site, and you must have a SMARTnet maintenance contract number to request software upgrades from Cisco.com.

This service pack requires an automatic reboot of the sensor to apply the changes. Inline network traffic will be disrupted during the reboot.

You cannot uninstall the 7.0(9)E4 service pack. You must reimage the sensor using a system image file, which causes all configuration settings to be lost.

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

The Cisco.com IP address has been changed in the Auto Update configuration.


Caution In IPS 7.0(9)E4 the default value of the Cisco server IP address has been changed from 198.133.219.25 to 72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on your sensor, you may need to update firewall rules to allow the sensor to connect to this new IP address.

Using automatic update:

When you upgrade the AIM IPS or 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 AIM IPS and NME IPS have been automatically updated, you can reenable heartbeat reset. If you do not disable heartbeat reset, the update can fail and leave the AIM IPS and NME IPS in an unknown state, which can require a system reimage to recover.

If you are using automatic update from an FTP or SCP server with a mixture of platforms that are supported by IPS 7.0(9)E4 as well as platforms that are not supported by IPS 7.0(9)E4, we recommend that you create a separate automatic update directory for the IPS 7.0(9)E4 files. Modify the automatic update configuration for sensors supporting IPS 7.0(9)E4 to point to the new directory. Placing the IPS 7.0(9)E4 files in the automatic update directory for those sensors not supporting IPS 7.0(9)E4 results in those sensors constantly downloading the update and generating errors during the attempted update.

Using manual update:

If you want to manually update your sensor, copy the IPS 7.0(9)E4 update files to the directory on the server that your sensor polls for updates.

When you upgrade the AIM IPS or 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 NME IPS in an unknown state, which can require a system reimage to recover.

Global correlation health status defaults to red and changes to green after a successful global correlation update. Successful global correlation updates require a DNS server or an HTTP proxy server. Because DNS and HTTP proxy server configuration features are beginning with IPS 7.0(1)E3, they are unconfigured after an upgrade from 6.x to 7.0(1)E3 or higher. As a result, global correlation health and overall sensor health status are red until you configure a DNS or HTTP proxy server on the sensor. If the sensor is deployed in an environment where a DNS or HTTP proxy server is not available, you can address the red global correlation health and overall sensor health status by disabling global correlation and configuring sensor health status not to include global correlation health status.

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 the AIM IPS and NME IPS, use the bootloader.

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


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.

Upgrading to IPS 7.0(9)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.

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-AIM-K9-7.0-9-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-AIM-K9-7.0-9-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.

For More Information

For a list of the caveats associated with this release, see Caveats.

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

Logging In to the IDM

The IDM is a web-based, Java Web Start application that enables you to configure and manage your sensor. The web server for the IDM resides on the sensor. You can access it through Internet Explorer or Firefox web browsers.


Note The IDM is already installed on the sensor.


To log in to the 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 the 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 window appears.

Step 3 To launch the IDM, click Run IDM. The JAVA loading message box appears. 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. The IDM on ip_address dialog box appears. To create a shortcut for the IDM, click Yes. The Cisco IDM Launcher dialog box appears.


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


Step 5 To authenticate the IDM, enter your username and password, and click OK. The IDM begins to load. If you change panes from Home to Configuration or Monitoring before the 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 the 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 the IDM by double-clicking the IDM shortcut icon. You can also close the The Cisco IPS Device Manager Version window. After you launch the IDM, is it not necessary for this window to remain open.



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

Service Programs for IPS Products

Obtaining and Installing the License Key

Uninstalling the License Key

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:

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 the IDM or the IME, for the IDM choose Configuration > Sensor Management > Licensing, and for the 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 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:

AIM IPS

IDSM2

NME IPS

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

Obtaining and Installing the License Key

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

Using the IDM or the IME

Using the CLI

Using the IDM or the IME


Note In addition to a valid Cisco.com username and password, you must also have a Cisco Services for IPS service contract before you can apply for a license key.


To obtain and install the license key, follow these steps:


Step 1 Log in to the IDM or the IME using an account with administrator privileges.

Step 2 For the IDM choose Configuration > Sensor Management > Licensing. For the IME choose Configuration > sensor_name > Sensor Management > Licensing. The Licensing pane displays the status of the current license. If you have already installed your license, you can click Download to save it if needed.

Step 3 Obtain a license key by doing one of the following:

Click the Cisco.com radio button to obtain the license from Cisco.com. The IDM or the IME contacts the license server on Cisco.com and sends the server the serial number to obtain the license key. This is the default method. Go to Step 4.

Click the License File radio button to use a license file. To use this option, you must apply for a license key at this URL: www.cisco.com/go/license. The license key is sent to you in e-mail and you save it to a drive that the IDM or the IME can access. This option is useful if your computer cannot access Cisco.com. Go to Step 7.

Step 4 Click Update License, and in the Licensing dialog box, click Yes to continue. The Status dialog box informs you that the sensor is trying to connect to Cisco.com. An Information dialog box confirms that the license key has been updated.

Step 5 Click OK.

Step 6 Go to www.cisco.com/go/license. Fill in the required fields. Your license key will be sent to the e-mail address you specified.


Caution You must have the correct IPS device serial number because the license key only functions on the device with that number.

Step 7 Save the license key to a hard-disk drive or a network drive that the client running the IDM or the IME can access.

Step 8 Log in to the IDM or the IME.

Step 9 For the IDM choose Configuration > Sensor Management > Licensing. For the IME choose Configuration > sensor_name > Sensor Management > Licensing.

Step 10 Under Update License, click the License File radio button.

Step 11 In the Local File Path field, specify the path to the license file or click Browse Local to browse to the file.

Step 12 Browse to the license file and click Open.

Step 13 Click Update License.


Using the CLI


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


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.

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

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

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

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


Note You are prompted for a password.


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

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

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


Note You are prompted for a password. 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


Note The directory specification should be an absolute path to the desired file.


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

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


Note The directory specification should be an absolute path to the desired file. The remote host must be a TLS trusted host.


Installing the License Key

To install the license key, follow these steps:


Step 1 Apply for the license key at this URL: www.cisco.com/go/license.


Note In addition to a valid Cisco.com username and password, you must also have a Cisco Services for IPS service contract before you can apply for a license key.


Step 2 Fill in the required fields. Your Cisco IPS Signature Subscription Service license key will be sent by e-mail to the e-mail address you specified.


Note You must have the correct IPS device serial number because the license key only functions on the device with that number.


Step 3 Save the license key to a system that has a Web server, FTP server, or SCP server.

Step 4 Log in to the CLI using an account with administrator privileges.

Step 5 Copy the license key to the sensor.

sensor# copy scp://user@192.168.1.2/24://tftpboot/dev.lic license-key

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

Restrictions and Limitations

The following restrictions and limitations apply to Cisco IPS 7.0(9)E4 software and the products that run it:

IPS 7.0(9)E4 does not support the 4200 series sensors. We recommend you upgrade to IPS 7.(x)E4.

IPS 7.0(9)E4 does not support the AIM SSC-5, which is only supported in IPS 6(x)E4.

In IPS 7.0(9)E4 the default value of the Cisco server IP address has been changed from 198.133.219.25 to 72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on your sensor, you may need to update firewall rules to allow the sensor to connect to this new IP address.

If you get an unauthorized error message while configuring an automatic update, make sure you have the correct ports open on any firewalls between the sensor and Cisco.com. For example, you need port 443 for the initial automatic update connection to www.cisco.com, and you need port 80 to download the chosen package from a Cisco file server. The IP address may change for the Cisco file server, but you can find it in the lastDownloadAttempt section in the output of the show statistics host command.

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.

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

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

The AIM IPS and the NME IPS do not support the IPv6 features, because the router in which they are installed does not send them IPv6 data. IPv6 inspection is also not supported on the IDSM2. The switch is able to send IPv6 packets to the IDSM2, but this has not been tested and is not officially supported. There is no support for IPv6 on the management (command and control) interface. With ASA 8.2.1, the AIP SSM supports 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.

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.

CSM and MARS do not support IPv6.

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 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, 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.

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

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.

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.

The 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 the IDM, they are turned into something unrecognizable and you will not be able to delete or edit the resulting object through the 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 the SensorApp is reconfigured, there is a short period when the SensorApp is unable to respond to any queries. Wait a few minutes after reconfiguration is complete before querying the SensorApp for additional information.

The IDM and the 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.

For More Information

For detailed information on RADIUS authentication, for the IDM refer to Configuring Authentication and Users, and for the CLI refer to Configuring User Parameters.

For the procedure for using the unlock command to unlock a locked user account, refer to Unlocking Locked Accounts.

For more information on interoperability between modules, refer to Interoperability With Other IPS Modules.

For more information about IPv6, switches, and lack of VACL capture, see IPv6, Switches, and Lack of VACL Capture.

Recovering the Password

This section describes how to recover the password for the sensor. It contains the following topics:

Understanding Password Recovery

Recovering the IDSM2 Password

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 3 lists the password recovery methods according to platform.

Table 3 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 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

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 IDSM2, refer to Installing the IDSM2 System Image.

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

Recovering the AIM IPS Password

To recover the password for the AIM IPS, use the clear password command. You must have console access to the AIM IPS and administrative access to the router.

To recover the password for the AIM IPS, follow these steps:


Step 1 Log in to the router.

Step 2 Enter privileged EXEC mode on the router.

router> enable
 
   

Step 3 Confirm the module slot number in your router.

router# show run | include ids-sensor
interface IDS-Sensor0/0
router#
 
   

Step 4 Session in to the AIM IPS.

router# service-module ids-sensor slot/port session
 
   

Example:

router# service-module ids-sensor 0/0 session
 
   

Step 5 Press Control-shift-6 followed by x to navigate to the router CLI.

Step 6 Reset the AIM IPS from the router console:

router# service-module ids-sensor 0/0 reset
 
   

Step 7 Press Enter to return to the router console.

Step 8 When prompted for boot options, enter *** quickly. You are now in the bootloader.

Step 9 Clear the password.

ServicesEngine boot-loader# clear password
 
   

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


Recovering the NME IPS Password

To recover the password for the NME IPS, use the clear password command. You must have console access to the NME IPS and administrative access to the router.

To recover the password for NME IPS, follow these steps:


Step 1 Log in to the router.

Step 2 Enter privileged EXEC mode on the router.

router> enable
 
   

Step 3 Confirm the module slot number in your router.

router# show run | include ids-sensor
interface IDS-Sensor1/0
router#
 
   

Step 4 Session in to the NME IPS.

router# service-module ids-sensor slot/port session
 
   

Example

router# service-module ids-sensor 1/0 session
 
   

Step 5 Press Control-shift-6 followed by x to navigate to the router CLI.

Step 6 Reset the NME IPS from the router console.

router# service-module ids-sensor 1/0 reset
 
   

Step 7 Press Enter to return to the router console.

Step 8 When prompted for boot options, enter *** quickly. You are now in the bootloader.

Step 9 Clear the password.

ServicesEngine boot-loader# clear password
 
   

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


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 the 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 the IDM

To disable password recovery in the 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 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.
