Information
The 'apache' account must not be used as a regular login account, and should be assigned an invalid or 'nologin' shell to ensure that the account cannot be used to login.
Rationale:
Service accounts such as the 'apache' account represent 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
