Internet Engineering Task Force (IETF) A. Backman, Ed. Request for Comments: 8936 Amazon Category: Standards Track M. Jones, Ed. ISSN: 2070-1721 Microsoft M. Scurtescu Coinbase M. Ansari A. Nadalin Independent November 2020 Poll-Based Security Event Token (SET) Delivery Using HTTP Abstract This specification defines how a series of Security Event Tokens (SETs) can be delivered to an intended recipient using HTTP POST over TLS initiated as a poll by the recipient. The specification also defines how delivery can be assured, subject to the SET Recipient's need for assurance. Status of This Memo This is an Internet Standards Track document.

Introduction and Overview This specification defines how a stream of Security Event Tokens (SETs) [RFC8417] can be transmitted to an intended SET Recipient using HTTP [RFC7231] over TLS. The specification defines a method to poll for SETs using HTTP POST. This is an alternative SET delivery method to the one defined in [RFC8935]. Poll-based SET delivery is intended for scenarios where all of the following apply: * The recipient of the SET is capable of making outbound HTTP requests. * The transmitter is capable of hosting a TLS-enabled HTTP endpoint that is accessible to the recipient. * The transmitter and recipient are willing to exchange data with one another. In some scenarios, either push-based or poll-based delivery could be used, and in others, only one of them would be applicable. A mechanism for exchanging configuration metadata such as endpoint URLs, cryptographic keys, and possible implementation constraints such as buffer size limitations between the transmitter and recipient is out of scope for this specification. How SETs are defined and the process by which security events are identified for SET Recipients are specified in [RFC8417]. 1.1.
