Gateway

Choosing RADIUS Authentication Protocols

January 8, 2024

Contributed by:

NetScaler Gateway supports implementations of RADIUS that are configured to use several protocols for user authentication, including:

Password Authentication Protocol (PAP)
Challenge-Handshake Authentication Protocol (CHAP)
Microsoft Challenge-Handshake Authentication Protocol (MS-CHAP Version 1 and Version 2)

If your deployment of the NetScaler Gateway is configured to use RADIUS authentication and your RADIUS server is configured to use PAP, you can strengthen user authentication by assigning a strong shared secret to the RADIUS server. Strong RADIUS shared secrets consist of random sequences of uppercase and lowercase letters, numbers, and punctuation and are at least 22 characters long. If possible, use a random character generation program to determine RADIUS shared secrets.

To further protect RADIUS traffic, assign a different shared secret to each NetScaler Gateway appliance or virtual server. When you define clients on the RADIUS server, you can also assign a separate shared secret to each client. If you do this, you must configure separately each NetScaler Gateway policy that uses RADIUS authentication.

When you create a RADIUS policy, you configure shared secrets on NetScaler Gateway as part of the policy.
