Access Control FOR SERVICES

Authentication: The process of verifying the identity of a user or system attempting to access the service. This can involve username/password authentication, biometric verification, multi-factor authentication (MFA), etc.
Authorization: Once authenticated, determining what resources or operations the authenticated entity is allowed to access or perform. This is typically managed through roles, permissions, and policies.
Roles and Permissions: Assigning roles to users or entities based on their job function or purpose, and associating these roles with specific permissions that dictate what actions they can perform within the service.
Access Control Models: Different models such as discretionary access control (DAC), mandatory access control (MAC), role-based access control (RBAC), attribute-based access control (ABAC), etc., define how permissions are assigned and enforced.
Policy Enforcement: Implementing mechanisms and tools to enforce access control policies consistently across the service infrastructure, ensuring that only authorized actions are allowed.
Audit and Monitoring: Monitoring access attempts and activities to detect unauthorized access or policy violations, and logging these events for audit purposes.
Single Sign-On (SSO): Facilitating seamless access across multiple services or applications with a single set of credentials, enhancing user experience while maintaining security.
Access Revocation: Ability to revoke access rights immediately when an individual no longer requires access or in case of security incidents.
Encryption and Data Security: Ensuring that data in transit and at rest is protected through encryption and other security measures to prevent unauthorized access even if authentication and authorization measures are bypassed.
