Authentication and authorization protocols

There are many protocols associated with authentication and authorization in an enterprise. A common approach will be to log on within the domain using directory services. This may use Kerberos as an SSO protocol. In other cases, we must look at solutions where this is not possible. Remote access could be an example, or securing access to the network using the new zero-trust approach. In this section, we will take a look at the available protocols.

Remote Authentication Dial-In User Server (RADIUS)

RADIUS is a well-supported Authentication, Authorization, and Accounting (AAA) protocol. This is used to gain access to networks, so it could be used to grant access over a Virtual Private Network (VPN) or anything that will require remote access. Radius could also be used to gain access to a switch that is Ethernet 802.1 X-compliant. This could also be used to gain access to a Wireless Access Point (WAP). AAA allows the RADIUS client (network...
