What is the process called when a cloud service user is assigned different access permissions based on their role?

The correct answer is the process known as Role-Based Access Control (RBAC). This method involves assigning permissions to users based on their specific roles within an organization. Essentially, rather than granting access at an individual level, access rights are tied to the various roles users might hold, simplifying the management of user permissions.

In a cloud environment, RBAC enhances security and helps streamline administrative tasks by ensuring that users can only access resources that are necessary for their job functions. For example, an employee in the finance department may have access to financial records, while someone in HR would have access to employee records. This reduces the risk of unauthorized access to sensitive information and allows for easier auditing of who has access to what resources.

This contrasts with other options like Mandatory Access Control (MAC), which enforces access controls strictly based on system policies, often without regard for user roles. Discretionary Access Control (DAC) allows users to control access to their own data, granting broader permissions that can lead to security vulnerabilities. Lastly, Network Access Control (NAC) focuses on controlling devices that can connect to the network rather than managing user permissions based on their roles. Each of these alternatives shows a different management style of access rights, emphasizing why Role-Based Access Control is
