Cisco Intrusion Prevention System Device Manager Configuration Guide for IPS 7.0

Logging In to the Sensor

Note All IPS platforms allow ten concurrent CLI sessions.

This chapter explains how to log in to the various Cisco IPS platforms, and contains the following sections:

•Supported User Roles

•Logging In to the Appliance

•Connecting an Appliance to a Terminal Server

•Logging In to the AIM IPS

•Logging In to the AIP SSM

•Logging In to the IDSM2

•Logging In to the NME IPS

•Logging In to the Sensor

Supported User Roles

You can log in with the following user privileges:

•Administrator

•Operator

•Viewer

•Service

The service role does not have direct access to the CLI. Service account users are logged directly into a bash shell. Use this account for support and troubleshooting purposes only. Unauthorized modifications are not supported and will require the sensor to be reimaged to guarantee proper operation. You can create only one user with the service role.

When you log in to the service account, you receive the following warning:

******************************** WARNING *****************************************

UNAUTHORIZED ACCESS TO THIS NETWORK DEVICE IS PROHIBITED.

This account is intended to be used for support and troubleshooting purposes only. 
Unauthorized modifications are not supported and will require this device to be 
re-imaged to guarantee proper operation.

**********************************************************************************

Note The service role is a special role that allows you to bypass the CLI if needed. Only a user with administrator privileges can edit the service account.

Note 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.

For More Information

•For more information on the service account, see Understanding the Service Account.

•For the procedures for adding and deleting users, see Configuring Authentication and Users.

Logging In to the Appliance

Note You must initialize the appliance (run the setup command) from the console. After networking is configured, SSH and Telnet are available.

You can log in to the appliance from a console port. To log in to the appliance, follow these steps:

Step 1 Connect a console port to the sensor to log in to the appliance.

Step 2 Enter your username and password at the login prompt.

Note The default username and password are both cisco. You are prompted to change them the first time you log in to the appliance.You must first enter the UNIX password, which is cisco. Then you must enter the new password twice.

login: cisco

IPS 4240#

For More Information

•For the procedure for connecting an appliance to a terminal server, see Connecting an Appliance to a Terminal Server.

•For the procedure for using the setup command to initialize the appliance, see Basic Sensor Setup

Connecting an Appliance to a Terminal Server

A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other serial devices. You can use terminal servers to remotely manage network equipment, including appliances.

To set up a Cisco terminal server with RJ-45 or hydra cable assembly connections, follow these steps:

Step 1 Connect to a terminal server using one of the following methods:

•For terminal servers with RJ-45 connections, connect a 180 rollover cable from the console port on the appliance to a port on the terminal server.

•For hydra cable assemblies, connect a straight-through patch cable from the console port on the appliance to a port on the terminal server.

Step 2 Configure the line and port on the terminal server. In enable mode, enter the following configuration, where # is the line number of the port to be configured.

config t

line #

login

transport input all

stopbits 1

flowcontrol hardware

speed 9600

exit

exit

wr mem

Step 3 Be sure to properly close a terminal session to avoid unauthorized access to the appliance.

If a terminal session is not stopped properly, that is, if it does not receive an exit(0) signal from the application that initiated the session, the terminal session can remain open. When terminal sessions are not stopped properly, authentication is not performed on the next session that is opened on the serial port.

Caution Always exit your session and return to a login prompt before terminating the application used to establish the connection.

Caution If a connection is dropped or terminated by accident, you should reestablish the connection and exit normally to prevent unauthorized access to the appliance.

Logging In to the AIM IPS

This section describes how to session to the AIM IPS, and contains the following topics:

•The AIM IPS and the session Command

•Sessioning In to the AIM IPS

The AIM IPS and the session Command

You session in to the AIM IPS from the router console. Because the AIM IPS does not have an external console port, console access to the AIM IPS is enabled when you issue the service-module ids-sensor slot/port session command on the router, or when you initiate a Telnet connection into the router with the slot number corresponding to the AIM IPS port number. The lack of an external console port means that the initial bootup configuration is possible only through the router.

When you issue the service-module ids-sensor slot/port session command, you create a console session with the AIM IPS, in which you can issue any IPS configuration commands. After completing work in the session and exiting the IPS CLI, you are returned to the Cisco IOS CLI.

The session command starts a reverse Telnet connection using the IP address of the IDS-Sensor interface. The IDS-Sensor interface is an interface between the AIM IPS and the router. You must assign an IP address to the IDS-Sensor interface before invoking the session command. Assigning a routable IP address can make the IDS-Sensor interface itself vulnerable to attacks, because the AIM IPS is visible on the network through that routable IP address, meaning you can communicate with the AIM IPS outside the router. To counter this vulnerability, assign an unnumbered IP address to the IDS-Sensor interface. Then the AIM IPS IP address is only used locally between the router and the AIM IPS, and is isolated for the purposes of sessioning in to the AIM IPS.

Note Before you install your application software or reimage the module, opening a session brings up the bootloader. After you install the software, opening a session brings up the application.

Caution If you session to the module and perform large console transfers, character traffic may be lost unless the host console interface speed is set to 115200/bps or higher. Use the show running config command to check that the speed is set to 115200/bps.

For More Information

For the procedure for setting up an unnumbered IP address, refer to Using an Unnumbered IP Address Interface.

Sessioning In to the AIM IPS

Note You must initialize the AIM IPS (run the setup command) from the router. After networking is configured, SSH and Telnet are available.

Use the service-module ids-sensor slot/port session command to establish a session from the AIM IPS to the module. Press Ctrl-Shift-6, then x, to return a session prompt to a router prompt, that is, to go from the AIM IPS prompt back to the router prompt. Press Enter on a blank line to go back to the session prompt, which is also the router prompt. You should only suspend a session to the router if you will be returning to the session after executing router commands. If you do not plan on returning to the AIM IPS session, you should close the session rather than suspend it.

When you close a session, you are logged completely out of the AIM IPS CLI and a new session connection requires a username and password to log in. A suspended session leaves you logged in to the CLI. When you connect with the session command, you can go back to the same CLI without having to provide your username and password.

Note Telnet clients vary. In some cases, you may have to press Ctrl-6 + x. The control character is specified as ^^, Ctrl-^, or ASCII value 30 (hex 1E).

Caution If you use the disconnect command to leave the session, the session remains running. The open session can be exploited by someone wanting to take advantage of a connection that is still in place.

To open and close sessions to the AIM IPS, follow these steps:

Step 1 Log in to the router.

Step 2 Check the status of the AIM IPS to make sure it is running.

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

Service Module is Cisco IDS-Sensor0/1

Service Module supports session via TTY line 322

Service Module is in Steady state

Logging In to the NME IPS

This section describes how to session to the NME IPS, and contains the following topics:

•The NME IPS and the session Command

•Sessioning In to the NME IPS

The NME IPS and the session Command

You session in to the NME IPS from the router console. Because the NME IPS does not have an external console port, console access to the NME IPS is enabled when you issue the service-module ids-sensor slot/port session command on the router, or when you initiate a Telnet connection into the router with the slot number corresponding to the NME IPS port number.
