    Access control

    Access control is the practice of regulating and managing user permissions and privileges to resources, systems, or data. It ensures that only authorized individuals or entities can access specific resources and perform permitted actions based on their roles or privileges.

    Key Concepts

    Access control systems typically involve:

    • Authentication: Verifying the identity of users
    • Authorization: Determining what resources users can access
    • Role-based access control (RBAC): Assigning permissions based on user roles
    • Principle of least privilege: Granting only the minimum permissions necessary

    Implementation

    Effective access control requires:

    1. Clear definition of user roles and responsibilities
    2. Regular review and updates of access permissions
    3. Monitoring and logging of access attempts
    4. Implementation of strong authentication mechanisms
