Final answer:
The correct answer to what limits users based on privileges is Access control. It's a key security measure that helps protect resources and ensures only authorized individuals get access to specific data or areas.
Step-by-step explanation:
The question asks about what limits users can do or see based on privileges. The correct answer is b) Access control. Access control is a security measure that determines who or what is allowed to access or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization. Access controls ensure that only authorized individuals have access to specific resources and information, thus protecting the privacy and confidentiality of data. For instance, in a corporate setting, an employee might only have access to the files that are relevant to their work, but not to the company's financial records, unless they have been granted the necessary privileges.
When comparing it to the provided information about governments needing to have restricted and controlled power to prevent tyranny, the concept of a firewall is metaphorically used to describe how individual rights should be protected. A firewall in technology serves a similar purpose to access control, it blocks unauthorized access while permitting outward communication. This can be seen as analogous to the way in which a government can protect individual rights by controlling the extent of its own powers.
