In this episode, we break down Control 03.01.05 – Least Privilege — a core access control principle that ensures users and system processes only receive the minimum necessary permissions to perform their tasks. This control is not about restriction — it’s about precision. By limiting access based on job roles, reviewing privileges regularly, and enforcing proper separation, you reduce the risk of unauthorized access and lateral movement within your systems. 📋 What you’ll learn in this video: - What Control 03.01.05 – Least Privilege requires - Key implementation strategies and real-world examples - New DoD-defined minimum requirements for security functions, security-relevant information, and access review frequency - What auditors look for in your System Security Plan (SSP) - Why Least Privilege is both a technical setting and a cultural mindset Whether you’re an IT manager, system admin, or compliance officer, understanding this control is critical to building secure, audit-ready infrastructure. 👉 Visit https://dodecacore.com to see how our platform enforces least privilege, manages access controls, and generates compliance documentation — all in one place. 🔔 Subscribe to follow along as we explain every control in NIST SP 800-171 Rev. 3 — one video at a time. #LeastPrivilege #AccessControl #NIST800171 #CMMCLevel2
