Greg Conti, Director of Security Research at IronNet Cybersecurity, and I have been studying the role of assumptions in daily cybersecurity decisions. These unconscious beliefs can be quite dangerous when they go unchecked. Conti and Conti share some of their favorite cybersecurity assumptions. The goal is to heighten your awareness when a dangerous assumption is in play so that it can be addressed before it leads to an unproductive action. The Economist magazine reported how over 40,000 fMRI studies were based on algorithms that contained faulty assumptions.”]
