New and Changed Information
IDM 7.3.1 has the following new features:
•Support for IPS 7.3(1)E4.
IDM 7.3.1 is included in IPS 7.3(1)E4.
•Threat profile enhancements:
–You no longer have to manually tune signature sets for deployment.
–You can create a new signature instance using a threat profile, view a list of signatures contained in a certain profile, and create a new signature instance without applying a threat profile.
–You can apply/remove a threat profile for a signature instance, assign a threat profile to a virtual sensor, apply a template to a signature instance, and create a new signature instance with a threat profile applied on the fly.
–You can view the list of signatures that are present in a threat profile.
–You can remove a threat profile from the virtual sensor or remove the threat profile from the signature instance assigned to the virtual sensor.
–You can determine if a threat profile has been applied on a sensor.
–You can preserve user tunings. A message is displayed stating that the tunings are preserved when the threat profile is applied and your tunings will be preferred in case of a conflict. When a threat profile is applied on a signature instance, the IDM first applies the user tunings (current configuration) on the default configuration, then it applies the signature template to the complete configuration. During this process if a tuned signature is found, it will not be changed.
–Configuration > Signature Configuration > Add Policy/Clone Policy
You can add a threat profile here.
–Configuration > Policies > Signature Definitions
You can manage signature instances and threat profiles here.
–Configuration > Policies > Signature Definitions > sig0
Right-click the signature instance to apply, remove, replace templates, and delete signature instances. You can identify the threat profile on the bottom pane and mouse-over on the signature instance, which shows the threat profile name, profile version, signature version, and virtual sensor assignment.
–Configuration > Policies > Signature Definitions > sig0 > All Signatures > Threat Profile
Apply/replace/delete threat profiles here.
–Configuration > Policies > IPS Policies
You can identify the threat profile for the virtual sensor.
–Edit Virtual Sensor
You can identify the threat profile and can creat a new signature instance with a threat profile.
–Threat profiles provide Cisco-recommended set of signatures for different deployment profiles: Edge, Data Center, Web Applications, and SCADA.
–Threat profiles are delivered along with signature sets as a part of signature updates; your tunings are retained.
•Link Aggregation Control Protocol (LACP) support for the IPS 4500 series sensors:
–Provides scalability with an aggregate throughput of 80 Gbps with 16 sensors connected in a port channel.
–Helps the switch to detect the IPS failures faster and redistribute the traffic among other members of the port channel.
–Configuration > Interfaces > LACP
You can configure LACP here. You must have inline VLAN pairs configured first on your sensor and LACP configured on a Cisco Nexus 7K or Catalyst 6K switch.
–Sensor Monitoring > LACP > LACP Neighbor
You can view the LACP neighbors with the system details.
–Sensor Monitoring > LACP > LACP Internal
You can view the LACP internals with their system details.
•Improved and stable SMB Advanced signature engine:
–Enhanced inspection for MSRPC request handling code execution vulnerability
–Support for Big-endian MSPRC traffic
–Multiple DCE-RPC requests in single WriteAndX command
–SMB AndX command with wordcount 0
–SMB Predator Decoy trees evasion
–Buffer overflow attempt to exploit the call_trans2open function of Samba
–Evasion with small RPC segments in conjunction with window resizing
•Base64 decoding support for HTTP traffic:
–Inspection capability improvement with cross site scripting (XSS)
–Prevents client-side exploits by inspecting Base64 encoded data
–Decodes the HTML, CSS, and XML Base64 encoded data carried in the HTTP response payload
•Improved software capacity to enable additional signatures
•TCP failover/fallback session continuity

Starting the IDM
Note After you upgrade the IPS software on your sensor, you must restart IDM so that the latest features for the new software version are present in IDM.
There are two ways to start the IDM:
•Cross launch from the IME (recommended)
Open the IME and click Configuration. All IDM functionality is available in the IME.
•Through a browser
Enter the IP address of the target sensor in the address window as follows:https://xx.xx.xx.xx
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://192.0.2.1:1040).
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, 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 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 6 To authenticate the IDM, enter your username and password, and click OK. Both the default username and password are cisco. You were prompted to change the password during sensor initialization. The IDM begins to load. If you change panes from Home to Configuration or Monitoring before the IDM has completed 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 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, it is not necessary for this window to remain open.
Restrictions and Limitations
The following restrictions and limitations apply to Cisco IDM 7.3.1:
•After you upgrade the IPS software on your sensor, you must restart the IDM so that the latest features for the new software version are present in the IDM.
•The IDM has been built and tested with JAVA 7 Update 45 and earlier. The IDM is not compatible with JAVA 7 Update 51. For IDM to function, you must use the older version of Java . Refer to CSCum55433 if you must use Java 7u51 and there is no option to use earlier versions.
•The IDM opens 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 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 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 the CLI as an identifier, for example, names of time periods, inspect maps, server and URL lists, and interfaces.
For More Information
For more information about MySDN, refer to MySDN.
This section lists the unresolved caveats:
•CSCum55433 IDM is being blocked by Java after an upgrade to Java 7.51
•CSCum57386 IDM sometimes doesn't load with complete configuration
