Question

Why does Security Advisor report "Apache vhosts are not segmented or chroot()ed"?

Answer

You will see this notice when your server is not configured to load user sites in a jailed environment. When a server is configured without jailed users, users may have access to data outside of their environment. The notice can be removed by following the procedure below.

Procedure

1. Check to see if mod_ruid2 is installed on your server. This can be done from the command line or WHM.
