What is CageFS?

The benefits of CageFS are:

Only safe binaries are available to the user.

The user will not see any other users and would have no way to detect the presence of other users & their usernames on the server.

The user will not be able to see server configuration files, such as Apache config files.

Users will have the limited view of /proc file system, and will not be able to see other’ users processes.
