There are no shortage of acronyms in the security space, and shifting towards centralised-security, rather than perimeter-based-security, has added even more. As I have been playing with solutions around centralised identity services, such as Oracle’s Identity Cloud Service, I have found myself spending more and more time in IETF RFCs in order to understand these concepts. While there is a lot of value in the standards documents, they assume a lot of knowledge and I often found myself wishing for a slightly more approachable, high level description of the elements I was dealing with. While there is something tempting about being part of the secret ‘We read the security RFCs’ club, I resisted this, and took it upon myself to provide this higher level overview of these important concepts.
