Episode 141: Principle of Least Privilege and RBAC

Security in networking isn’t just about blocking attacks—it’s about minimizing exposure by limiting what users and systems can access. In this episode, we examine the Principle of Least Privilege (PoLP), which states that users should have only the access they need to perform their duties—no more, no less. You’ll learn how this concept applies not only to user accounts but also to devices, applications, and even services within the network. Limiting privilege helps reduce the damage caused by accidental changes or compromised accounts.We also explore Role-Based Access Control (RBAC), a structured way of applying least privilege across departments, job functions, and user groups. We cover the differences between role-based and discretionary models, how RBAC integrates with Active Directory and network devices, and why it’s a common requirement in audits and compliance frameworks. This episode is vital for understanding how to implement logical controls and maintain secure boundaries between users and systems.
