What is a typical example of a system requirement in a control strategy?

A typical example of a system requirement in a control strategy is maintaining separate levels of security for users and the system administrator. This requirement is critical because it enhances the overall security posture of the system by ensuring that users do not have access to sensitive administrative controls or data. This separation helps protect the system from unauthorized access and potential misuse, while also allowing administrators to manage the system effectively without interference from regular users. In control strategies, such security measures are often fundamental to enforcing accountability, compliance, and risk management protocols within an organization.

While the other options present important characteristics, they do not directly align with the concept of control strategies. Backup procedures are essential for recovery but are more about continuity than active controls. Real-time data processing speaks to performance rather than control, and prioritizing user access relates more to usability than security management. These additional requirements support the system's functionality but do not embody the core principles of a control strategy as clearly as establishing distinct security levels does.
