There are many different authentication mechanisms that may be implemented on any network system. Sometimes we need to authenticate systems or application, but most of the time when we think about authentication, user authentication is what comes to mind.

Depending on the function of the system or$.$the design of the network, we will run into different forms of user authentication. This could be as simple as local user authentication to a single system or a complex directory service using Kerberos to provide single sign$-$on $($SSO$)$ to many different users and systems. In this lab will take a look at how to manage and securing different authentication methods that are commonly found in networks.
