Looking for some advice on Java Deserialization Protection and Jetbrains IDEA

[Decio_VD]

Hello,
I need some advice regarding the "Known Vulnerable Processes Protection" for Linux.
This protection seems to prevent the jetbrains IDE IntelliJ IDEA (version 2023.3 build 223.7571.182) from running because of the Java Deserialisation Protection module (regarding log4j https://blog.jetbrains.com/platform/2022/02/removing-log4j-from-the-intellij-platform/ ).

What is the best way to get this IDE to run while maintaining the protection?

Thanks in advance.

Hi @Decio_VD ,

Thank you for writing to live community!

If you have a prevention alert from Java Deserialisation protection module , you can create alert exceptions for the same. Creating alert exceptions disables the Java deserialisation protection module for the initiator process and should allow you to run the application.

However, this is not just the end of it. Once created, we recommend you to right click on the alert and retrieve alert dump data file and open a case with our support team describing the situation well. The TAC/engineering will analyse the logs and can do  a detailed/granular level whitelist in form of a content update or provide you a support exception that will create more granularity for the same.  Once the whitelist mechanism is provided, you can remove the exceptions and your should have the protection on the process while allowing the specific action for the application process.

Steps: 

1. Create alert exceptions: Right click on alert> Manage Alert> create alert exception. You should get an option to create profile based(only for targetted endpoints) or global(for all the endpoints)
2. Retrieve alert data: Right click on alert> Retrieve Additional Data> Retrieve Alert data. Navigate to action center and wait for the dump file to be loaded. Download the named dump file and open a support case for investigation.

Hope this helps!
