Information
The apache account must not be used as a regular login account, so it should be assigned an invalid or 'nologin' shell to ensure it cannot be used to log in.
Rationale:
Service accounts such as the apache account are a risk if they can be used to get a login shell to the system.
Solution
Change the apache account to use the 'nologin' shell or an invalid shell such as '/dev/null':
# chsh -s /sbin/nologin apache
