Conference agenda, 26th of October

REST services are stateless. In other words, there are no sessions between REST API producers and consumers. Given the difficulties of securing sessions, this is A Good Thing from a security perspective.
Access to REST APIs is incumbent on the presentation of a valid security token. Typically, this is an access token issued by an OAuth authorization server. The authZ server maintains a session with the user agent so that the user does not need to re-authenticate each time a new access token is needed. This is not entirely unproblematic, as will be illustrated through a discussion of logout and the tenuous implementation of silent authentication in client libraries. Conversely, I will argue for leveraging authorization server sessions to raise the consent game to a level where it truly serves the interests of the user.
In summary, while REST APIs are stateless and do not maintain a session, access control architectures *do* rely on sessions trying to provide a good user experience while enforcing authorization policies.

This talk lays it out for you. We dive into the technicalities of cookies, JWT tokens and Authorization headers. You will learn how to assess your past choices, and how to substantiate future decisions.
