Confining Java application with SELinux

Confining Java application with SELinux

Dear all,

I have a use case where a Java application needs to be confined with
SELinux. What should I consider taking care of to achieve this?

Thanks.

I want to confine a Java application with SELinux policy so I wanted to know
how I can really do that. Will the application be visible to the native
platform with SELinux? Or only the Java VM is visible and that we use Java
ACL to confine the application inside the VM?

Thanks.

You can only confine the JVM.  If there is more than one application in
the JVM, they will not be separable by SELinux.  So if you want
separation between two or more Java applications enforced by SELinux,
they would have to run in separate JVMs.

I am not quite sure of the nomenclature here, but you can confine the
entire java process, as long was you wrap the startup script.

cat /usr/bin/myjavaapp
#!/usr/bin/sh
java -class myjavaapp.jar

chcon -t myjavaapp_exec_t /usr/bin/myjavaapp

...
