Access Control Models

Access control models are frameworks that determine how and when users can access data or resources. They specify rules to ensure only authorized individuals can view or modify information. Common models include Discretionary Access Control (DAC), where owners set permissions; Mandatory Access Control (MAC), which enforces strict policies based on security labels; and Role-Based Access Control (RBAC), granting access based on a user's role within an organization. These models help protect sensitive data by controlling access based on rules, permissions, or roles, ensuring security and proper management of resources.
