[LINUX_Newbies] protecting the root user in Centos

 

I googled this and got an option I thought would really work for me.

1. disallow ssh login by root
2. restrict su to root to the wheel group
3. disallow remote and local login for root

#2 was accomplished with this command:

auth required /lib/security/pam_wheel.so use_uid

however, this allows users in the wheel group to su to root without
entering a password. In my mind, this is only slightly better than
allowing ssh root login. Any suggestions?

Thanks,
Loyal
