Managing sudo Access

In this lab, we will look at how to manage access to `sudo`. We will strengthen `sudo` security by removing unnecessary default settings and configure `sudo` to always require a password. Then, we'll permit specific user accounts to use `sudo`. *This course is not approved or sponsored by Red Hat.*
