Episode 21 — Apply Access Control Models to Real-World Scenarios
Access control models translate policy into predictable, auditable decisions, and the SSCP exam often tests whether you can pick the simplest model that truly fits the scenario. This episode contrasts discretionary access control (DAC), mandatory access control (MAC), role-based access control (RBAC), and attribute/claims-based access control (ABAC), clarifying what each optimizes for and how they relate to classification, segregation of duties, and least privilege. We explain subjects, objects, and permissions; lattice ideas in MAC; permission aggregation by roles in RBAC; and contextual evaluation in ABAC that uses attributes like device posture, location, and time. You’ll learn how these models appear in common platforms, how to avoid over-granting through role explosion, and how to connect the model choice to evidence such as policy definitions, mapping tables, and decision logs that prove the control is working as intended.
We then apply the models to concrete situations so you can reason quickly under exam pressure. For a regulated records system, MAC with labels and clearances controls read and write paths; for a mid-size enterprise, RBAC anchors permissions to job functions and simplifies joiner–mover–leaver workflows; for modern SaaS and APIs, ABAC evaluates attributes and risk signals at request time to make context-aware decisions; and for small, isolated tool stacks, DAC may be sufficient if ownership is clear and audit coverage is strong. Troubleshooting sections show how to prevent role drift, design ABAC policies that remain explainable, and document compensating controls when legacy systems cannot meet the preferred model. The result is a practical playbook for selecting, implementing, and validating access control models that reduce risk without paralyzing the business.
