The Security Transformation track at QCon London focused on discussing how security should change to match digital transformation and dev/ops practices. The topic is often overlooked in discussions about digital transformation, but it's essential for evolving developer security practices. The speaker covered three aspects of DevSecOps: security technologies, methodologies, and the shared ownership philosophy. The conference was well-attended, with strong interest from developers who want to learn more about security and improve their own practices. QCon London is a great platform for in-depth discussions on complex topics like security transformation.
