ProNet, a leading technology firm, has been dynamically evolving its internal infrastructure to cater to an expanding workforce and changing business needs. The company's current project involves enhancing the overall security of its internal platforms. The company's security team is focusing on a robust access control system. To make the system efficient, it needs to implement a model that would define access based on roles within the organization, where specific roles would have predefined access to certain resources, and the roles can be assigned to multiple users. The aim is to decrease the administrative work involved in assigning permissions and ensure that users gain only the necessary permissions in line with their job functions. Which access control model best suits ProNet's requirement?
Correct Answer: C
Role-Based Access Control (RBAC) is a widely adopted access control model suitable for environments where permissions need to be aligned with job roles. Here's why RBAC is the best choice for ProNet: * Definition: RBAC assigns permissions to roles rather than individuals. Users are then assigned to these roles. * Efficiency: Reduces administrative overhead by allowing permissions to be managed at the role level. * Scalability: Suitable for large organizations as roles can be easily modified to reflect changes in job functions. * Security: Ensures that users have only the necessary permissions, reducing the risk of unauthorized access. Implementation: * Define Roles: Identify the various roles within the organization (e.g., Admin, Developer, HR). * Assign Permissions: Map the necessary permissions to each role. * User Assignment: Assign users to appropriate roles based on their job functions.
