Continuing from the previous post which dealt with the core concepts around performing authentication and authorisation in a distributed environment, this post expands upon those concepts, looking at additional factors for authorisation decisions, including supplementary information, authentication challenges and risk assessment. While basic authentication and authorisation requirements can be met through the use of JWTs and OAuth, this post shifts to tackling bespoke requirements, outlining potential services which could provide capabilities above and beyond what is captured in those standards.

Access Management and Micro-services – Part 2: Authentication and Authorisation
In the previous post in this series we examined at a high-level how responsibilities for authentication and authorisation are distributed in a micro-services architecture. In this post, the strategies and technologies that underpin the implementation of authentication and authorisation will be explored further, with the core access management services providing authentication services, which support individual services performing authorisation. This discussion is actually split across two posts, as authentication and authorisation are core parts of the access management services, and require extensive discussion, with this post focusing upon the core capabilities, and the following post focussing upon more advanced authentication and authorisation requirements.

JWTs? JWKs? ‘kid’s? ‘x5t’s? Oh my!
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.
Multi Factor Authentication is Critical for Everyone
In today’s environment where systems run in the cloud and so much business and personal activity occurs online, passwords are not strong enough by themselves to protect applications. Scandals about password breaches seem to happen on a regular basis. It’s easy to find many case studies where passwords have been compromised as a result of malware, email scams and other techniques. The key point is that no matter how strong our passwords, no matter how much we educate our users, there will be situations where people are caught off guard and click on the wrong link, look at the wrong email or open the wrong document. Once this happens, our passwords can be compromised.
