This presentation explores the ESRM framework through the lens of red teaming, highlighting its essential role in mitigating unforeseen risks. We delve into methodologies that strategically blend red team tactics with ESRM principles to enhance organizational resilience. The session will dissect real-world examples, demonstrating how Red Teaming effectively uncovers previously unknown vulnerabilities and strengthens security postures against evolving threats. Through case studies of unconventional stress tests of EP programs, active assailant measures, mail screening processes, and counter-drone systems, the presentation will showcase the importance of conducting hands-on testing and experimentation across the security industry to counter ever-evolving threats.
