Qradar Support

The MSS now fully supports the Qradar SIEM from IBM in CEF log format. Qradar is an excellent SIEM but requires classifying and mapping every event type it sees to an internal category. Qradar comes with a large number of common IDS rules (~50,000) already classified but not mapped.  Besides having to manually map all these rules  Qradar-MSS users  would also need to continuously create additional Qradar IDs (Qids) to map to the much larger rule set used by the MSS (which  changes daily). All this required a mechanism to update Qradar dynamically as new rules are published. With this update released today, no manual classification or mapping operations are necessary.

The MetaFlowsCEF log source automatically parses the 13 event types generated by the MSS and presents them in the Qradar default view. All MSS events are automatically mapped to new or existing Qids without any user manual operations. This makes the Qradar SIEM much easier to use.

To setup Qradar for the MSS perform the following steps:

    1. Download the MetaFlowsCEF log source https://nsm.metaflows.com/sensordevicetype-search-ContentExport-20180809173340.zip to the Qradar box
    2. Import it with the command /opt/qradar/bin/contentManagement.pl -action import -f sensordevicetype-search-ContentExport-20180809173340.zip
    3. Verify the import was successful and assign the MetaFlows sensors to this log source. Also make a note of the log source ID assigned by Qradar to the MetaFlowsCEF log source (something like 400[1-9]).
    4. Edit the file mss.sh of all sensors and add the line export QRADAR=1.
    5. On one of the sensors you designate as the main Qradar updater, create the file /nsm/etc/qradar.ini to allow the sensor to communicate to the Qradar server (see an example below). Also add the line export QRADARLOGSOURCEID=<logsourceid>; where <logsourceid> is the number you noted in step 3. Probably something like 4001, or 4002, etc..
    6. Restart the sensors

Sample qradar.ini:

certificate_file = /nsm/etc/qradar.pem
auth_token = f3f1201b-3562-46d1-9b8b-9a1623870000
server_ip =


/nsm/etc/qradar.pem is a copy of the file located at /etc/httpd/conf/certs/cert.cert on your Qradar box
auth_token is obtained from your QRADAR application
server_ip is the IP address of your Qradar box.

The Qradar updater sensor will automatically add to Qradar new IDS rules added by the sensor’s rule update  (which will be the same across all your sensors). This will happen through the Qradar API in the background as the sensor is running. The first time, the updater is run, it will have to catch up with about 50,000 definitions; so it will take many hours. Subsequent updates will take less time.

After each Qradar update, the email associated with the sensor owner will receive a summary of the update process.

Qradar integration is a bit complex; so do not hesitate to contact support@metaflows.com for any questions.
