Answer-4: Roles represent a job function or responsibility and have associated permissions.
Question-5. What are permissions in RBAC?
Answer-5: Permissions are approvals to perform certain operations on resources.
Question-6. How are users assigned in RBAC?
Answer-6: Users are assigned one or more roles, which in turn grant access through permissions.
Question-7. What is role hierarchy in RBAC?
Answer-7: Role hierarchy allows roles to inherit permissions from other roles.
Question-8. What are constraints in RBAC?
Answer-8: Constraints are rules that place restrictions on roles, users, or permissions.
Question-9. What is separation of duties in RBAC?
Answer-9: It's a principle ensuring that no user has enough access to misuse the system on their own.
Question-10. What is least privilege in RBAC?
Answer-10: It refers to granting users the minimum level of access needed to perform their duties.
Question-11. Can RBAC support multi-tenancy?
Answer-11: Yes, RBAC can be extended to support multi-tenant environments with tenant-specific roles.
Question-12. What are the advantages of RBAC?
Answer-12: RBAC improves security, reduces administrative work, and simplifies auditing.
Question-13. What are role permissions?
Answer-13: They are operations that a specific role is authorized to perform.
Question-14. How does RBAC improve compliance?
Answer-14: It enforces structured access control, which helps meet regulatory requirements.
Question-15. What is a session in RBAC?
Answer-15: A session is a mapping between a user and activated roles at a specific time.
Question-16. How is RBAC implemented in cloud environments?
Answer-16: RBAC is implemented using IAM services provided by cloud platforms.
Question-17. What is the difference between static and dynamic separation of duties?
Answer-17: Static enforces constraints during role assignment, dynamic enforces them during session activation.
Question-18. How do you manage role explosion?
Answer-18: By creating composite roles and using role hierarchies effectively.
Question-19. What is role mining?
Answer-19: Role mining is the process of analyzing user permissions to create efficient role definitions.
Question-20. What tools support RBAC?
Answer-20: Tools include AWS IAM, Azure RBAC, Okta, and Active Directory.
Question-21. Can RBAC be used with ABAC?
Answer-21: Yes, hybrid models combining RBAC and ABAC are used for fine-grained control.
Question-22. What is a role-based policy?
Answer-22: It is a policy that grants permissions based on roles assigned to users.
Question-23. What is a composite role?
Answer-23: A composite role is a role that includes other roles to aggregate permissions.
Question-24. What are the challenges of RBAC?
Answer-24: Challenges include role explosion, maintenance, and mapping business functions accurately.
Question-25. What is role engineering?

Answer-39: A component that enforces access control decisions based on policies.
Question-40. What is policy decision point (PDP)?
Answer-40: A component that evaluates access requests against policies.
Question-41. What is context-aware RBAC?
Answer-41: RBAC enhanced with context data like location, time, or device.
