CSOC Tooling

Working as a CSOC analyst is becoming more complex, with alert volumes increasing rapidly as perimeters are integrated, tools, regulatory constraints, and the need to detect suspicious behaviour as quickly as possible.

Even though attracting talent must continue to be a major challenge, implementing good CSOC tools to simplify daily life is also critical. As is usually the case with the triptych: process, competent personnel, and technology, which must be adjusted to implement an efficient CSOC. As a result, the technology part of this article will focus on the CSOC tooling.

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).

Manual interactions with the third-parties have an expensive cost and require staff that are focused on other concerns. Evaluation of the cybersecurity posture of third parties do not diverge from that trend. However, as a breach in a supplier’s Information System may have a huge impact on your own, how to conciliate a proper risk assessment and agility in an ever-growing interconnected world?
