With CageFS:

  • Users only have access to safe files.
  • Users cannot see other users and have no way to detect the presence of other users or user names on the server.
  • Users cannot see server configuration files, like Apache config files.
  • Users have a limited view of their own processing file system, and cannot see other users' processes.

This innovative technology operates on the following principles:

  • Only allow safe binaries to be available to users.
  • Remove each user's access to ALL SUID scripts.
  • Limit each customer's access to the /proc filesystem.
  • Prevent symbolic link attacks.

Even with this extensive security, a user's environment is fully functional, and users do not feel restricted in any way. CageFS is completely transparent to the end user, yet impregnable to a hacker.
