This chapter explains how to bootstrap and add the following network-based IDS and IPS devices to MARS:
•
Cisco IDS 3.1 Sensors
•Cisco IDS 4.0 and IPS 5.x Sensors
•Cisco IPS Modules
•ISS Site Protector
•ISS RealSecure 6.5 and 7.0
•IntruVert IntruShield
•Snort 2.0

Cisco IDS 3.1 Sensors
Before you add the Cisco IDS 3.1 device, make sure that you have configured the Cisco IDS device for the MARS to retrieve the device configuration. The device configuration would be used for mapping of the logs received by MARS.
When configuring the IDS device to send logs to the MARS, you must use the exact name of the MARS Appliance. To determine the name of the appliance, select Admin > System Setup > Configuration Information and review the value in the Name field.
Configure Sensors Running IDS 3.1
Step 1 Log in to the Cisco IDS device.
Step 2 Change to directory that has all the configurations files that need to be edited:
Step 3 You need to edit 4 files (organizations, hosts, routes and destinations) that are in this directory.
In the organizations file add a line indicating your organization name or grouping;
where 1 is the item number followed by the organization name protego. If there is already item in this file, simply increase the item number (has to be unique).
Figure 6-1 Add MARS Information to Cisco IDS 3.1 Organizations File
In the hosts file add a line indicating your MARS appliances' name associated to the organization that was previously added in the organizations file;
e.g., 2001.1 pnmars.protego
where 2001.1 is a unique item number followed by the MARS appliances' name and organization name protego. If there is already items in this file, simply increase the item number (has to be unique).
Figure 6-2 Add MARS Information to Cisco IDS 3.1 Hosts File
In the routes file add a line indicating your MARS appliances' name and its IP address;
e.g., pnmars.protego 1 10.1.1.10 45000 1 5
where pnmars.protego is the MARS's name (with organizations' name) followed by 1 then the MARS appliances' IP address.
The 45000 is the port number that the IDS will use to send its logs to MARS. Add a 1 follows by a 5 at the end of this line (these numbers are not used by MARS).
Figure 6-3 Add MARS Information to Cisco IDS 3.1 Routes File
In the destinations file add a line indicating your MARS appliances' name (as defined in the routes file) the client process that the appliance is using to listen for events from the sensor (in this case smid), and the list of log types you want sent to the appliance as a comma separated list:
e.g., pnmars.protego smid ERRORS, EVENTS, COMMANDS
where pnmars.protego is the MARS's name (with organizations' name) followed by smid and the list of log types that the loggerd daemon will publish to the appliance.
Figure 6-4 Add MARS Information to Cisco IDS 3.1 Destinations File
Step 4 Once you've edited these four files (organizations, hosts, routes, and destinations), reboot the sensor using the following commands:
a. nrstop
b. nstart
Add and Configure a Cisco IDS 3.1 Device in MARS
To add and configure a Cisco IDS device in MARS, follow these steps:
Step 1 Click Admin > System Setup > Security and Monitor Devices > Add.
Step 2 Select Cisco IDS 3.1 from the Device Type list.
Step 3 Enter the hostname of the sensor in the Device Name field.
The Device Name value must be identical to the configured sensor name.
Step 4 Enter the administrative IP address in the Access IP field.
Step 5 Enter the administrative IP address in the Reporting IP field.
The Reporting IP address is the same address as the administrative IP address.
Step 6 Select either SSH or TELNET.
Step 7 Enter "netrangr" as the Login and its Password.
When adding a Cisco IDS 3.1 device, use the netrangr username or some other username that is not the root login for the sensor. Using the root login causes MARS to fail to parse the login prompt correctly, which in turn, cause the Test Connectivity to fail.
Figure 6-5 Configure Cisco IDS 3.1
Step 8 For attack path calculation and mitigation, add networks into the Monitored Networks field.
a. Click the Select a Network or Define a Network radio button.
•In the Select a Network list, click a network.
•In the Define a Network field, enter its network IP and network mask information.
b. Click Add to move the selected networks into the Monitored Networks field.
Step 9 (Optional) To discover the device settings, click Discover.
Step 10 Click Submit.
Cisco IDS 4.0 and IPS 5.x Sensors
Adding a Cisco IDS or IPS network sensor to MARS involves two parts:
1. Bootstrap the Sensor
2. Add and Configure a Cisco IDS or IPS Device in MARS
3. Verify that MARS Pulls Events from a Cisco IPS Device
The following topic supports Cisco IDS and IPS devices:
•View Detailed Event Data for Cisco IPS Devices
Note If you've imported your sensor definitions using the seed file format, as specified in Load Devices From the Seed File, page 2-24, you must define the networks monitored by the sensor.
Bootstrap the Sensor
Preparing a sensor to be monitored by MARS involves two steps:
•Enable the Access Protocol on the Sensor
•Enable the Correct Signatures and Actions
Enable the Access Protocol on the Sensor
The configuration of the sensor depends on the version of the software that is running on the sensor. The following topics identify the requirements of each version:
•Cisco IDS 4.x Software
•Cisco IPS 5.x Software
Cisco IDS 4.x Software
For Cisco IDS 4.x devices, MARS pulls the logs using RDEP over SSL. Therefore, MARS must have HTTPS access to the sensor. To prepare the sensor, you must enable the HTTP server on the sensor, enable TLS to allow HTTPS access, and make sure that the IP address of MARS is defined as an allowed host, one that can access the sensor and pull events. If the sensors have been configured to allow access from limited hosts or subnets on the network, you can use the accessList ipAddress ip_address netmask command to enable this access.
Cisco IPS 5.x Software
For Cisco IPS 5.x devices, MARS pulls the logs using SDEE over SSL. Therefore, MARS must have HTTPS access to the sensor. To prepare the sensor, you must enable the HTTP server on the sensor, enable TLS to allow HTTPS access, and make sure that the IP address of MARS is defined as an allowed host, one that can access the sensor and pull events. If the sensors have been configured to allow access from limited hosts or subnets on the network, you can use the access-list ip_address/netmask command to enable this access.
Enable the Correct Signatures and Actions
If the signature actions are correctly configured, MARS can display the trigger packet information for the first event that fires a signature on a Cisco IDS or IPS device. MARS is also able to pull the IP log data from Cisco IDS and IPS devices, however, this operation is system intensive. Therefore, you should select the set of signatures that generate IP log data carefully.
When configuring the active signatures on a Cisco IDS or IPS device, you must specify the alert action and the action that generates the desired data:
•To view trigger packets, you must enable the "produce-verbose-alert" action.
•To view IP logs, you must enable the alert or "produce-verbose-alert" action and the "log-pair-packets" action.
Caution Configuring IP logging and verbose alerts on the sensor is system intensive and does affect the performance of your sensor. In addition, it affects the performance of your MARS Appliance. Because of these effects, you be cautious in configuring signatures to generate IP logs.
Add and Configure a Cisco IDS or IPS Device in MARS
To add and configure a Cisco IDS or IPS device in MARS, follow these steps:
Step 1 Click Admin > System Setup > Security and Monitor Devices > Add.
Step 2 Do one of the following:
•Select Cisco IDS 4.0 from the Device Type list.
Figure 6-6 Configure Cisco IDS 4.0
•Select Cisco IPS 5.x from the Device Type list.
Figure 6-7 Configure Cisco IPS 5.x
Step 3 Enter the hostname of the sensor in the Device Name field.
The Device Name value must be identical to the configured sensor name.
Step 4 Enter the administrative IP address in the Access IP field.
Step 5 Enter the administrative IP address in the Reporting IP field.
The Reporting IP address is the same address as the administrative IP address.
Step 6 In the Login field, enter the username associated with the administrative account that will be used to access the reporting device.
Step 7 In the Password field, enter the password associated with the username specified in the Login field.
Step 8 In the Port field, enter the TCP port on which the webserver running on the sensor listens. The default HTTPS port is 443.
Note While it is possible to configure HTTP only, MARS requires HTTPS.
Step 9 To pull the IP logs from the sensor, select Yes in the Pull IP Logs box.
Step 10 For attack path calculation and mitigation, specify the networks being monitored by the sensor. Do one of the following:
To manually define the networks, select the Define a Network radio button.
a. Enter the network address in the Network IP field.
b. Enter the corresponding network mask value in the Mask field.
c. Click Add to move the specified network into the Monitored Networks field.
d. Repeat as needed.
To select the networks that are attached to the device, click the Select a Network radio button.
a. Select a network from in the Select a Network list.
b. Click Add to move the selected network into the Monitored Networks field.
c. Repeat as needed.
Step 11 To verify the configuration, click Test Connectivity.
Step 12 Click Submit.
Specify the Monitored Networks for Cisco IPS or IDS Device Imported from a Seed File
After you import a Cisco IPS or IDS device into MARS using a seed file, you must define the networks that are monitored by that sensor.
To define the networks monitored by a sensor, follow these steps:
Step 1 Click Admin > System Setup > Security and Monitor Devices.
Step 2 Select the check box next to the Cisco IPS or IDS device that was imported using a seed file. and click Edit.
Step 3 To specify the networks being monitored by the sensor, do one of the following:
To manually define the networks, select the Define a Network radio button.
a. Enter the network address in the Network IP field.
b. Enter the corresponding network mask value in the Mask field.
c. Click Add to move the specified network into the Monitored Networks field.
d. Repeat as needed.
To select the networks that are attached to the device, click the Select a Network radio button.
a. Select a network from in the Select a Network list.
b. Click Add to move the selected network into the Monitored Networks field.
c. Repeat as needed.
Step 4 To save your changes, click Submit.
Step 5 To enable MARS to start sessionizing events from this module, click Activate.
View Detailed Event Data for Cisco IPS Devices
You can view the trigger packets and IP log data associated with incidents reported by Cisco IDS 4.x and Cisco IPS 5.x devices, whether they are sensor appliances or modules. This information is useful when an in-depth understanding of the attack method is desired. MARS includes two event types that focus on the these two data types:
•Trigger packet data. Identifies the data that was being transmitted on the network the instant an alarm was detected. You can use this information to help diagnose the nature of an attack. The trigger packet provides a single data packet—the data packet that caused the alarm to fire.
•Packet data. Identifies the data that was being transmitted on the network the instant an alarm was detected. You can use this information to help diagnose the nature of an attack. Although the amount of data contained in an IP log varies based on sensor configuration, by default an IP log contains 30 seconds of packet data. To view this data, you must enable the Pull IP Logs option on the Cisco IPS device under Admin > System Setup > Security and Monitor Devices.
Note MARS does not collect this data for Cisco IDS 3.x devices.
For the correct signature settings required to generate this data, see Enable the Correct Signatures and Actions.
If the IP log feature is enable for the reporting Cisco IPS device, these event types are combined as part of the incident data. You can view this data by drilling down in an incident, expanding the desired event type (either Packet Data or Trigger Packet Data), selecting an event, and clicking on the RAW Events for this Session icon under the Reporting Device column of that event. The source, destination, and other data displayed for these events matches that of the original alert. In addition, this data appears hexadecimal and binary format.
Note The trigger packet and IP log data is stored using a base64-encoded format in the MARS database. Therefore, keyword search does not work on it if you just provide the search string.
Verify that MARS Pulls Events from a Cisco IPS Device
Note If the Test Connectivity operation does not fail when configuring a Cisco IPS device in the MARS web interface, then communications are enabled. This task allows you to further verify the alerts are generated and pulled correctly.
It is common to create benign events on the network to verify the data flow. To verify the data flow between a Cisco IPS device and MARS, perform the following tasks:
1. On the Cisco IPS device, enable and alert on the signatures 2000 and 2004. The signatures monitor ICMP messages (pings).
2. Ping a device on the subnet on which the Cisco IPS device is listening. The events are generated and pulled by MARS.
3. Verify that the events appear in the MARS web interface. You can perform a query using the Cisco IPS device.
4. Once the dataflow is verified, you can disable the 2000 and 2004 signatures on the Cisco IPS device.
Cisco IPS Modules
MARS can monitor Cisco IPS modules installed in Cisco switches and Cisco ASA appliances. To prepare these modules, you must perform the following tasks:
•Define the base module, either the router, switch, or Cisco ASA, as defined in Cisco Router Devices, page 3-1, Cisco Switch Devices, page 3-9, and Cisco Firewall Devices (PIX, ASA, and FWSM), page 4-1.
•Bootstrap the base module to enable SDEE traffic on the Cisco IPS module, to forward events to the MARS Appliance, and to enable MARS to access the SDEE events stored on the modules. Module access enables MARS to retrieve trigger packets and IP log information.
•Add the IPS feature set t the base module previously defined in the web interface.
This section contains the following topics:
•Enable DTM Support
•Enable SDEE on the Cisco IOS Device with an IPS Module
•Add an IPS Module to a Cisco Switch or Cisco ASA
The following topic also supports the configuration of the Cisco IPS modules:
•Verify that MARS Pulls Events from a Cisco IPS Device
Enable DTM Support
To support DTM, you must configure your IPS module as follows:
•Purchase or enable the IOS IPS feature set.
•Enable HTTPS for SDEE.
•Enable SSH to discover settings, which is the method recommended over Telnet.
Enable SDEE on the Cisco IOS Device with an IPS Module
In addition to enabling either Telnet or SSH for configuration discovery on a Cisco IOS device, you must also enable SDEE on the device that supports IPS module. SDEE is used to publish events to MARS about signatures that have fired.
To enable SDEE protocol on the Cisco IOS device that supports IPS module, perform the following steps:
Step 1 Log in to the Cisco IOS device using the enable password.
Step 2 Enter the following commands to enable MARS to retrieve the events from the IPS module:
Router(config)#ip http secure-server
Router(config)#ip ips notify sdee
Router(config)#ip sdee subscriptions 3
Router(config)#ip sdee events 1000
Router(config)#no ip ips notify log
Note The "no ips notify log" causes the IPS modules to stop sending IPS events over syslog.
Add an IPS Module to a Cisco Switch or Cisco ASA
You can enable in-line IPS functionality and signature detection in multi-purpose Cisco platforms. You can identify an IDS-M2 running in a Cisco Switch or an ASA-SSM running in a Cisco ASA. To represent either of these modules, you must define the settings for the module as part of the base platform, which must be previously defined under Admin > System Setup > Security and Monitor Devices.
To add an IPS module to a Cisco Switch of Cisco ASA, follow these steps:
Step 1 Click Admin > System Setup > Security and Monitor Devices.
Step 2 From the list of devices, select the Cisco switch or Cisco ASA to which you want to add the IPS module and click Edit.
Step 3 Click Add Module.
Step 4 Select Cisco IPS 5.x in the Device Type list.
For Cisco switches, you can also add a Cisco IPS 4.0 module or an IDS 3.1 module. You configure these modules just as you would a standalone sensor. For instructions on configuring these modules, refer to Cisco IDS 3.1 Sensors and Cisco IDS 4.0 and IPS 5.x Sensors.
Figure 6-8 Configure Cisco IPS 5.x
Step 5 Enter the hostname of the sensor in the Device Name field.
Step 6 Enter the administrative IP address in the Reporting IP field.
Step 7 The Reporting IP address is the same address as the administrative IP address.
Step 8 In the Login field, enter the username associated with the administrative account that will be used to access the reporting device.
Step 9 In the Password field, enter the password associated with the username specified in the Login field.
Step 10 In the Port field, enter the TCP port on which the webserver running on the sensor listens.
The default HTTPS port is 443.
Note While it is possible to configure HTTP only, MARS requires HTTPS.
Step 11 For attack path calculation and mitigation, specify the networks being monitored by the sensor. Do one of the following:
To manually define the networks, select the Define a Network radio button.
a. Enter the network address in the Network IP field.
b. Enter the corresponding network mask value in the Mask field.
c. Click Add to move the specified network into the Monitored Networks field.

b. Click Add to move the selected network into the Monitored Networks field.
c. Repeat as needed.
Step 12 Click Test Connectivity to verify the configuration.
Step 13 To save your changes, click Submit.
Step 14 To enable MARS to start sessionizing events from this module, click Activate.
ISS Site Protector
Note This topic describes how to use Site Protector to configure the ISS NIDS and HIDS; Site Protector is not a device type that can be monitored or used as an aggregation point for ISS event data from the perspective of MARS. MARS cannot parse event data from Site Protector, unless you develop a custom event parser for each event type as described in Adding User Defined Log Parser Templates, page 16-1.
MARS supports ISS NIDS and HIDS event retrieval via SNMP. However, when configuring ISS RealSecure sensors (NIDS) and hosts (HIDS), you must configure each active signature to send an alert to the MARS Appliance. This task can be very tedious as it must be done for each sensor and after each signature upgrade, as it resets the redirect configuration. One approach to simplifying this task is to use the ISS Site Protector management console to define these changes globally and apply them to each sensor.
ISS Site Protector 2.0 allows you to centrally manage SNMP alert destinations, such as the MARS Appliance, for group policies. You can then push these group policies to all desired host and network sensors. For each ISS signature update, you must specify the MARS Appliance as an SNMP alert destination before you apply the downloaded signatures to sensors using Site Protector.
Note By default, the group policy response configuration is supported only on Proventia G400 and G2000 models. For all other models, including the G100 mentioned, a firmware upgrade is required. See the documentation that came with ISS Site Protector for more information.
To perform the major configuration steps required to use Site Protector to forward the SNMP alerts generated by sensors to MARS Appliance, follow these steps:
Step 1 Using the Add Sensor Wizard, register the sensor to Site Protector Console.
Other methods exist for registering sensors in Site Protector. For more information on using the Wizard as well as these other methods, see Chapter 9, Registering Software Managed by SiteProtector, on page 105 at the following URL:
http://documents.iss.net/literature/SiteProtector/SPUserGuideforSecurityManagers20SP52.pdf
Step 2 Right-click the sensor to edit, and click Edit Settings on the shortcut menu.
The Edit Settings dialog appears.
Step 3 Create a new SNMP response that sends messages to the IP address of the MARS Appliance:
a. Select Response Objects from the settings tree.
b. Select the SNMP tab.
c. Click Add to create a new SNMP response object using the IP address of the MARS Appliance.
Step 4 Select the Security Events to configure new SNMP destination.
a. Select Security Events under the sensor folder.
b. Select the required security events from the Security Events tab.
The Group By button allows you to group policies using any number of parameters.
Note You can also select policies and edit them at the group level.
c. Click Edit to configure SNMP response of all the selected policies.
Step 5 Select the MARS Appliance on SNMP tab.
a. Enable all the security events by selecting the Enabled checkbox located at the top of the Edit Security Events dialog box.
a. Select the SNMP tab under Responses, and then select the Enabled checkbox next to the name of MARS Appliance created in Step 3.
a. Click OK.
The security events and updated response target are applied to the selected sensor during the next synchronization.
ISS RealSecure 6.5 and 7.0
To configure ISS RealSecure, you must perform the following four tasks:
1. Prepare each ISS sensor as follows:
•Edit the common.policy files to point to the MARS Appliance as an SNMP target.
•Modify the current.policy files to configure each signature so that the SNMP notification is a default response when triggered.
•Edit the response.policy files to specify the IP of the SNMP manager (MARS Appliance) and the community string.
•Restart the ISS daemon for the changes to take effect.
For more information, see Configure ISS RealSecure to Send SNMP Traps to MARS.
2. Add the ISS sensor to MARS as a network-based IDS device. For more information, see Add an ISS RealSecure Device as a NIDS.
3. Click Activate to enable proper processing of received events.
Configure ISS RealSecure to Send SNMP Traps to MARS
To configure an ISS RealSecure sensor, follow these steps:
Step 1 Log into the sensor.
Step 2 Locate the common.policy files in these directories:
Program Files\ISS\issSensors\server_sensor_1
Program Files\ISS\issSensors\network_sensor_1
/opt/ISS/issSensors/server_sensor_1
/opt/ISS/issSensors/network_sensor_1
Step 3 Open the common.policy files in a text editor.
Step 4 Change the line that reads:
to:
Manager =S <MARS's IP address>
If MARS Appliance's IP address is NATed, you may need to use the NATed address. If you use the MARS Appliance's IP address as the destination IP address, make sure the SNMP trap can reach MARS Appliance.
Step 5 Save these edited files and exit the editor.
Step 6 Locate the current.policy files in these directories:
Program Files\ISS\issSensors\server_sensor_1
Program Files\ISS\issSensors\network_sensor_1
/opt/ISS/issSensors/server_sensor_1
/opt/ISS/issSensors/network_sensor_1
Step 7 Open the current.policy files in a text editor.
Edit each signature to have SNMP as one of its responses, and set the choice for SNMP trap as default. For example, in this original signature:
[\template\features\AOLIM_File_Xfer\Response\];
[\template\features\AOLIM_File_Xfer\Response\DISPLAY\];
[\template\features\AOLIM_File_Xfer\Response\LOGDB\];
Insert the following bolded lines to make it look similar to the following:
[\template\features\AOLIM_File_Xfer\Response\];
[\template\features\AOLIM_File_Xfer\Response\DISPLAY\];
[\template\features\AOLIM_File_Xfer\Response\SNMP\];
[\template\features\AOLIM_File_Xfer\Response\LOGDB\];
Step 8 Save these edited files and exit the editor.
Step 9 Locate the response.policy files in these directories:
Program Files\ISS\RealSecure SiteProtector\Console
/opt/ISS/RealSecure SiteProtector/Console
Step 10 Edit the response.policy files to specify the IP of the SNMP manager (MARS Appliance) and the community string:
[\Response\SNMP\Default\];
to:
Manager =S <MARS's IP address> ;
Community = S <string> public;
If MARS Appliance's IP address is NATed, you may need to use the NATed address. If you use the MARS Appliance's IP address as the destination IP address, make sure the SNMP trap can reach MARS Appliance.
Step 11 Save these edited files and exit the editor.
Step 12 Restart the ISS daemon.
•For sensors installed on Microsoft Windows, restart it in the Services menu.
•For sensors installed on Linux, run:

IntruVert IntruShield
To configure IntruVert IntruShield in MARS, you must perform the following tasks:
1. Generate CSV file that identifies each of the IntruShield senor hosts by logging into the database to which IntruShield Manager writes and performing and saving a database query.
2. Configure the IntruShield Manager to send SNMP traps to the MARS Appliance
3. Define a host that represents the management console (IntruVert Manger) in MARS web interface.
4. From that host in the MARS web interface, import the IntruShield sensor seed file to identify the IntruVert sensors running on other hosts.
The following sections provide details on performing each of these tasks:
•Extracting Intruvert Sensor Information from the IntruShield Manager
•Configure IntruShield Version 1.5 to Send SNMP traps to MARS
•Configure IntruShield Version 1.8 to Send SNMP Traps to MARS
•Add and Configure an IntruShield Manager and its Sensors in MARS
Extracting Intruvert Sensor Information from the IntruShield Manager
IntruVert sensor information is saved in a database on the IntruShield Manager host. When you configure the MARS to add Intruvert sensors, you can manually add the mapping of each Intruvert sensor name or you can extract them as a seed file from the database on the Intruvert Manager.
Note The instructions apply for Intruvert IntruShield version 1.5. IntruVert supports both MySQL and Oracle.
To create a CSV file for IntruVert IntruShield 1.5, follow these steps:
Step 1 Log in to the database.
Step 2 Perform the query:
use lf; select name, ip_address from iv_sensor where ip_address is not NULL;
Step 3 Store the query result into a file, remove the header, trailer, and separator lines, and edit the result to a CSV format.
For example, the query result could be:
+------------+------------+
+------------+------------+
| intruvert1 | 0A010135 |
+------------+------------+
You would then edit the above file to appear as:
Step 4 Save the edited CSV file, move the file to an FTP server from which you can load the seed file using the MARS web interface.
