The Principle of Least Privilege
Every user, service account, and application should have access to only the resources it needs — nothing more. Overprivileged accounts are attacker goldmines.
IAM Design Patterns
- Role-Based Access Control (RBAC): Assign permissions to roles, not individuals. Users inherit permissions by joining roles.
- Attribute-Based Access Control (ABAC): Grant access based on attributes like department, location, or device health for fine-grained control.
- Just-in-Time Access: Issue elevated permissions for a time-limited window, automatically revoking them after the task completes.
