In a cloud-native world, your code is your infrastructure. If the code is hollow, the fortress falls. In this video, Sec Guy breaks down the Secure SDLC, explains how to use STRIDE for Threat Modeling, and details the difference between SAST (Whitebox) and DAST (Blackbox) testing. We also tackle the #1 API threat: BOLA (Broken Object Level Authorization).
