In this episode of the Cyber Resilience Brief, hosts Tova Dvorin and Adrian Culley clearly and practically explain some of the most commonly used — and most commonly misunderstood — terms in modern cybersecurity. Together, they break down: What Breach and Attack Simulation (BAS) actually means in practice How Advanced Persistent Threats (APTs) operate — and why persistence matters What Adversarial Exposure Validation (AEV) is (and what it isn’t) How CTEM (Continuous Threat Exposure Management) connects these concepts The difference between attack simulation and adversary emulation This episode focuses on plain-language explanations, real-world context, and why these terms exist in the first place. If you’ve ever heard these acronyms used interchangeably — or wanted a grounded explanation you can actually reuse — this episode is for you.
