Play the recording: Radius Futures

  • Why: RADIUS is still the default AAA protocol for network access (802.1X, Wi-Fi, VPN) and sits squarely in the PM's identity/authentication territory. Its 1993 design shows its age — known operational and security pain points — and "next-generation" standards work determines how network AAA coexists with modern identity stacks (OIDC, passkeys, workload identity).
  • What: A survey of real-world problems affecting RADIUS deployments, and how emerging next-generation RADIUS standards can reduce them (from abstract only).
  • How: Protocol-level standards evolution rather than a product; the abstract does not enumerate the specific extensions, so expect the detail to be in the talk itself.
  • Where applicable: Broadly applicable — any operator or enterprise running AAA today. Protocol work, not vendor-specific. The main caveat is that the abstract stays high level; the value depends on which concrete drafts/problems get named.
