Presentation: Why APIs Are Every Attacker's Favorite Target

APIs power virtually every web and mobile application, accounting for over 80% of all Internet traffic. And APIs are under attack. Gartner states APIs have become the “most frequent attack vector," resulting in hundreds of highly successful, high profile breaches. This API security presentation covers 1) why attackers love APIs, 2) real-world breaches (and how they map to the OWASP API Security Top 10), and 3) best practices to keep APIs secure.

Speaker: Dan Barahona

Dan is a cybersecurity leader with 25+ years of experience spanning vulnerability management, threat intelligence, SIEM, and API security. He is the founder of APIsec University, the world's largest API security training platform, which has grown to over 130,000 students — including security teams at 75% of the Fortune 100 — all through free, vendor-neutral courses complete with assessments and certificates.
