Shared secrets

A shared secret is a case-sensitive text string used to validate communications between a RADIUS server and client. You should configure shared secrets that are long enough and random enough to resist attack. You should avoid using the same shared secret throughout your network.

All network access servers and proxy servers are required to specify a secret to communicate with RADIUS. Each remote device may have a different secret. Each server configured with a secret is displayed in a summary list on the RADIUS shared secrets page.

Shared secrets are often configured through NAS and proxies. Smile's shared secret configuration is used when a separate configuration is required.
