RadSec

Showing TLS outer tunnel and required certificates

Before your access points are able to establish a valid RadSec connection (which can be considered an mTLS connection), the following requirements must be met regardless of the manufacturer of the access point.

  • Access Points require a valid client certificate (typically referred to as "RadSec Client Certificate" or "RadSec Certificate"). This client certificate must have the EKU Client Authentication (1.3.6.1.5.5.7.3.2) and not Server Authentication.

  • Access Points must trust the CA that issued the RADIUS Server Certificate.

  • RADIUSaaS must trust the CA that issued the RadSec client certificate on your access points.

The RadSec protocol requires a shared secret to compute the MD5 integrity checks. The RadSec RFC defines this shared secret as the literal string "radsec".
