There are several types of access control mechanisms that leaders should be aware of:
1. Discretionary Access Control (DAC): This allows the resource owner to decide who has access. 2. Mandatory Access Control (MAC): Access is determined by the system, based on a set of security policies. 3. Role-Based Access Control (RBAC): Access is assigned based on the user's role within the organization. 4. Attribute-Based Access Control (ABAC): Access is granted based on attributes (e.g., department, clearance level).
