In this episode of Cybersecurity Today: Weekend Edition, host Jim Love speaks with John Kindervag, the pioneer behind the Zero Trust model of cybersecurity. With over 25 years of industry experience, John delves into how the concept originated from his early work with firewalls, advocating for a system where no packet is trusted by default. He discusses the fundamental principles of Zero Trust, including defining protect surfaces, mapping transaction flows, and implementing microsegmentation. The conversation also touches on overcoming cultural and organizational challenges in cybersecurity, the inadequacies of traditional risk models, and adapting Zero Trust methodologies in the evolving landscape, including AI. Through thoughtful discourse and practical insights, John underscores the importance of strategic and tactical implementations in building resilient and secure systems.
