In a world filled with threats, how can we deploy APIs with confidence? In this talk, we'll review how biological immune systems solve the problem and dive into how similar concepts drive Salt Security's Kong Plugin. The issue is how to defend APIs against evolving adversaries without knowing in advance what their attacks will be...all while not over-alerting on false positives. Join us to learn about security standards, why AuthZ/AuthN aren't enough, and what we as professionals can do to enhance trust in an increasingly API driven world.
