- AAA is one of the basic tenants of network security,
and it's something you likely use every day in some form.
AAA stands for authentication, authorization,
and accounting, and this comes into play each time we log
into our laptop or our social media accounts.
We want to examine that in this lesson,
in terms of network security,
and what it looks like on our infrastructure,
including configuring a local AAA database,
and using TACACS+ and RADIUS.
