2.4.11 Packet Tracer – Configure Access Control (Answers)

Objectives

Part 1: Configure and Use AAA Authentication Credentials
Part 2: Configure and Use Email Services
Part 3: Configure and Use FTP Services

Background / Scenario

Authentication and authorization are distinct security processes in the world of identity and access management (IAM). Authentication uses passwords and other identification methods to confirm that users are who they say they are. By contrast, authorization assigns user permissions to the resources that the user is allowed access. In this Packet Tracer (PT) activity, you will configure authentication and authorization for network services including wireless network access, email, and FTP services.

Note: This activity opens in Physical mode. However, if you can also complete it in Logical mode.
