What role do Security Classes play in a system like Hyperspace?

In a system like Hyperspace, Security Classes play a crucial role in controlling the functionalities accessible to users. Each Security Class dictates what actions a user can perform, what data they can access, and the overall level of permissions granted. By defining these classes, the system ensures that sensitive data and critical functionalities are protected from unauthorized access. This structured approach allows for robust security measures and helps to maintain compliance with privacy regulations and operational policies within the system.

The other options, while relevant to different aspects of system management or user experience, do not accurately describe the primary function of Security Classes. For instance, determining hardware requirements pertains more to infrastructure needs rather than user permissions, billing rates are related to financial aspects of using the system, and evaluating user performance metrics involves assessing user activity, which falls outside the scope of what Security Classes are designed to manage.
