Since my last post several new features were introduced on QRadar. In the last couple of years, IBM is really trying to stay ahead of its competitors (and also trying to catch up and in some forgotten features). In this post I want to discuss about the new capabilities that I believe are significant improvements in the new versions of QRadar (7.2.5 – 7.2.7).
- Multitenancy: Probably the feature that all the SOC service providers were waiting for. Now it’s possible to have multiple clients in one single QRadar installation, meaning that if you monitor QRadar for more than one company now you can see all your clients in one single dashboard. This feature also allow you to assign a specific amount of EPS for each tenant, making it easy to control the SIEM usage for each client. There’s a lot of improvements with this feature, so if you want more information just check the official IBM video about this feature.
- Historical Correlation: Several times in the past I struggled with the fact it was not possible to apply a new offense rule to past events. I had to use several bash tricks to be able to replay logs. However, in the latest versions of QRadar it is possible to “replay” historical logs to figure out if your new offense rule happened in the past. IBM also has a good video about this topic.
- Deployment Editor: Finally IBM got rid of the java applet that managed the QRadar deployment. The new QRadar 7.2.7 allows you to manage your appliances through the web interface!
- Custom Action Scripts: This is a feature that can be powerful if well written or dangerous if misconfigured. It can be powerful because allow an offense to trigger any action on an external system, for example, allow you to write an script that creates a new firewall rule if an “brute-force offense” is observed. At same time this is a great feature, the pentester side of me can see a lot of potential vulnerabilities with this feature: basically you’re allowing an script to execute a command in a server based on an input of a log received from a non-trusted device, meaning that if someone properly craft a syslog, they may be able to inject a command into your script. It’s not easy, but it may be possible. So make sure you properly sanitize the inputs in your action script. Also, make sure you properly configure the access to the script file (since it probably will contain access keys to other systems)
- Data Obfuscation: This feature basically obfuscate sensitive data coming in the logs. For example: let’s say that your application use as user-id the credit card number of the customer (which is NOT recommended), then your application sends the user-id to QRadar as part of the logs of some action. With this feature, you can obfuscate the user-id to ensure your SOC team will NOT see the credit card number of your customers. Check this IBM video for more information, they discuss where you can apply data obfuscation and where you shouldn’t apply it.
There are several other new features in the new QRadar versions but the above are the ones that in my opinion really aggregated value to the tool! Check out the IBM channel on Youtube, you can find several videos about the new QRadar features! What is your favorite new QRadar feature?
