Answer:
B. Role-based access controls
Explanation:
Roll-based access control is a way to control access to the network and to data which depends on the position of employees in a department. This way the permission to access information are granted according to roles that are assigned to employees. This type of access control allows access privileges to employees only to the folders and data files which they need in order to perform their tasks and it does not allow them to access the data or information which is not relevant to them. This helps the department to secure the sensitive information and data files and reduces the risk of data breaches.
