Securing System Login RHEL7

The default settings applied to system login are based on what Red Hat deems basic security. These are the default setting and same world wide. Securing system login RHEL7 is very important and critical. So you must change it for all good reasons.

Authconfig has two tools that you can use to configure authentication: authconfig and authconfig-tui .

These two tools configure PAM for you in such a way that the changes are consistent throughout rpm updates.

The authconfig-tui tool is not as feature-rich as the plan authconfig tool, which I personally recommend to use for securing system login in RHEL7.

Another option is to manually edit the files located in /etc/pam.d if and when you know what you’re doing, but this is not recommended.

This small video will show you the steps in securing system login in RHEL7 servers. A must watch for every RHCE.
