Episode 71 — Apply SAML, RADIUS, Kerberos, and OAuth Where Each Fits Best
This episode explains how to choose between SAML, RADIUS, Kerberos, and OAuth based on the problem you are solving, which is a common ISSAP exam pattern because several options can sound correct while only one fits the architecture context. You’ll define what each protocol is designed to do, the trust assumptions it relies on, and the environments where it is strongest, such as SAML for enterprise federation and SaaS SSO, RADIUS for network access and device authentication workflows, Kerberos for Windows-centric internal authentication with strong mutual trust, and OAuth for delegated authorization and modern API access patterns. We’ll connect protocol choice to real constraints like legacy client support, token lifetimes, replay risk, network reachability, and operational troubleshooting, including common failure modes like clock skew in Kerberos, mis-scoped OAuth tokens, weak shared secrets in RADIUS, and brittle SAML assertions caused by mismatched attributes or certificate rollover.
