Role-Based Access Control (RBAC)

• Assigns permissions based on predefined user roles (e.g., Admin, Editor, Viewer)
• Simplifies access management by grouping permissions
• Ideal for applications with clear and stable role definitions
• Makes permission allocation straightforward and easy to maintain

Attribute-Based Access Control (ABAC)

• Grants access based on user or environmental attributes
  • Examples: location, time of access, device type
• Provides dynamic and context-aware access control
• More flexible than RBAC
• Well-suited for applications requiring fine-grained, situational permissions

Access Control Lists (ACLs)

• Define permissions per individual resource
• Allow highly granular control over access
• Each file, record, or object can have its own access rules
• Useful for resource-level permission management

Policy-Based Access Control (PBAC)

• Uses centralized policies to determine access
• Can evaluate multiple factors simultaneously
• Supports both RBAC and ABAC
• Ideal for complex systems with detailed access requirements
• Especially useful in microservices architectures due to layered control
