How does access control based on the user's role benefit an organization?

1. It allows users to dictate permissions

2. Rights are provided based on job functions, reducing administrative overhead

3. It eliminates the need for network monitoring

4. Individual user access can't be modified

The correct answer is: Rights are provided based on job functions, reducing administrative overhead

Access control based on a user's role, often termed Role-Based Access Control (RBAC), provides significant benefits to an organization, particularly in how permissions are managed in relation to job functions. When rights are assigned according to the specific roles or functions of users within the organization, it streamlines the process of granting and modifying access. This method reduces the complexity and administrative overhead associated with managing user permissions, as changes can be made at the role level rather than for each individual user. For example, if an employee transitions to a different team or department, rather than modifying access rights for each user, the organization only needs to update access permissions for the respective role. This not only simplifies the management of access controls but also enhances security by ensuring that users only have access to the information necessary to carry out their job functions, thereby adhering to the principle of least privilege. While other options present concepts related to user permissions or network management, they do not accurately reflect the fundamental advantages of role-based access control. For instance, roles do not give users the authority to dictate permissions themselves, nor do they eliminate the need for monitoring, as constant oversight is still crucial for ensuring compliance and security. Additionally, the notion that individual user access cannot be modified misrepresents
