Engineer Briefing

A secure network must answer an important question:

"Who is allowed to access this system?"

Before allowing access, networks must verify identity.

This process is called:

Authentication

Enterprise networks use authentication to protect:

• Network devices.
• Servers.
• Wireless networks.
• User accounts.

Mission Objectives

By the end of this mission, students should understand:

• Authentication concepts.
• Authorization and accounting.
• The AAA framework.
• RADIUS and TACACS+.
