#127 - How to Stop Bad Guys from Staying on Your Network (with Kevin Fiscus)

In this episode of CISO Tradecraft, G Mark Hardy and guest Kevin Fiscus discuss the challenges of cybersecurity and the importance of prioritizing security decisions. Fiscus emphasizes the need for effective protective controls and detection measures, as well as the limitations of protective controls and the importance of detection. He suggests a "Detection Oriented Security Architecture" (DOSA) that includes high-fidelity, low-noise detection, automated response, and continuous monitoring. Fiscus also discusses the concept of cyber deception and proposes a new approach to cybersecurity that involves redirecting attackers to a decoy environment.
