How to configure firewall for different Java programs?
I'm having some trouble getting the proper configuration on my firewall for Java programs. My current setup is to only allow the bare minimum permissions on each program (that is, protocols/IPs/ports) and block everything else for anything unknown.
Problem is, particularly for programs written in Java, that I cannot easily differentiate between some programs when all of them require internet access. Currently all firewall rules are constrained to a single executable file, allowing access for it only, but Java works by running all programs by the very same executable (java.exe in program files).
So, if I deny permissions to java.exe, NO Java program can access the network (losing functionality). If I grant permissions to java.exe, ALL Java programs get the very same access level (which is a security risks and sort of defeats the purpose of a firewall). What I want is to give each Java program different access levels, just as I can with every other program.
Has anyone faced that problem? How can I do to assign different rules for each program individually?
