Final answer:
Job rotation.
The access control method that includes switching work assignments at preset intervals is Job rotation.
It is used within organizations to enhance security through preventing prolonged control by any single individual over a sensitive process or financial transaction.
Other methods such as mandatory vacations, least privilege, and separation of duties also contribute to a secure and controlled work environment.
Step-by-step explanation:
The access control method that includes switching work assignments at preset intervals is known as Job rotation. Job rotation is an effective approach to prevent fraud and errors since it involves regularly moving employees between different jobs or tasks.
This method helps ensure that no single individual has control over all aspects of a financial transaction or sensitive process, thereby enhancing security within an organization.
Mandatory vacations are also useful in access control as they can reveal fraudulent activities that might only be detectable when the regular employee is absent.
Least privilege is a principle where users are given the minimum levels of access — or permissions — needed to perform their job functions.
Separation of duties, on the other hand, is a control measure that splits critical tasks among different people to reduce the risk of error or inappropriate actions.
The access control method that involves mandatory vacations can also help detect fraud, as an employee’s work is covered by someone else during their absence, potentially uncovering any wrongdoing.
Applying the least privilege principle ensures that the potential damage one user can inflict is minimized.
Separation of duties is a key component in internal controls and prevents conflicts of interest by spreading tasks and associated privileges for a specific security process among multiple people.
