IETF Captive Portal Interaction Working Group

Interception techniques need to become more effective and fail-safe as endpoints become inherently more secure. The IETF Captive Portal Interaction (CAPPORT) Working Group will define secure mechanisms and protocols to:

• Allow endpoints to discover that they are in this sort of limited environment.
• Provide a URL to interact with the Captive Portal.
• Allow endpoints to learn about parameters of their confinement.
• Interact with the Captive Portal to obtain information such as status and remaining access time.
• Optionally, advertise a service whereby devices can enable or disable access to the Internet without human interaction. (RFC 7710 may be a full or partial solution to the first two bullets).
