On a security audit performed on our production Linux servers , we were asked to remove nobody user if no application are using it.I checked and could see that there are no files owned by 'nobody' user.find / -path /proc -prune -o -user nobody -ls'nobody' user does not have a login shell, similarly any user who does not have a login, Can it pose any security threat?  Is it advisable to delete these users without a login shell?# grep nobody /etc/passwdnobody:x:99:99:Nobody:/:/sbin/nologinPlease give your thoughts.
