Overview As application developers, we achieve amazing results quickly by leveraging a rich ecosystem of freely available libraries, modules and frameworks that provide ready-to-use capabilities and abstract away from underlying complexity. This is so foundational to how we work that we’ll nonchalantly build and publish an app that pulls in hundreds of dependencies without even thinking about it. And it’s only fairly recently, in the wake of some very high profile and high impact compromises, that we’ve started to reckon with the fact that this wonderful ecosystem is also a security quagmire.
