The BIND user account, named by default, 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.
Service accounts such as the named account represent a risk if they can be used to get a login shell to the system.
Not Applicable
Check the named login shell in the /etc/passwd file:
# grep named /etc/passwd
named:x:25:25:Named:/var/named:/sbin/nologin
The named account shell must be /sbin/nologin or /dev/null similar to the entry shown.
Change the named account to use the nologin shell as shown:
# chsh -s /sbin/nologin named
/sbin/nologin
