Episode 62: Monitoring and Least Privilege (Domain 2)

Monitoring and the principle of least privilege are two complementary pillars of proactive cybersecurity, enabling both visibility and access limitation. In this episode, we discuss how effective monitoring—using tools like SIEMs, endpoint detection platforms, and behavioral analytics—gives defenders real-time and historical insight into system behavior, user activity, and threat trends. We pair this with a deep dive into the least privilege model, where users and systems are granted only the minimum access necessary to perform their roles. Least privilege reduces the risk of lateral movement and privilege escalation during an attack, limiting the blast radius if an account is compromised. Combined with strong monitoring, this model allows teams to detect deviations from normal behavior quickly and respond with context. Together, monitoring and least privilege don’t just prevent unauthorized activity—they expose it and contain it.
