Resiliency is the ability of organizations, relying more and more on computing tools, to “survive” in case of IT tools’ failures. Considering the current cyber threats, this aspect has never been so important and preoccupying for Security & IT Experts. In fact, Belgium registered a rise of 30% in cybercrimes between 2018 and 2O19 (source: ccb.belgium.be). Choosing the right cybersecurity partner is now a major challenge.

How to evaluate an “OAuth/OpenID Connect” system from a security point of view?

This post presents a collection of security-oriented validation points that should be verified on a system using OAuth/OpenID Connect (OpenID Connect will be called OIDC in the rest of the post). Therefore, it assumes you are familiar with all the concepts related to OAuth/OIDC. All references to OAuth refer to OAuth 2.0.
