Computer security programs should include all of the following hardware precautions EXCEPT:

Physical and environmental security for payroll hardware is a key component of internal controls. Servers and computer equipment are sensitive to their environment; however, high humidity (Option B) is actually a threat to hardware, as it can cause condensation and short-circuit sensitive electronic components. Conversely, very low humidity can lead to static electricity buildup. Therefore, hardware should be kept in climate-controlled rooms (Option C) with regulated humidity and temperature levels. Other standard precautions include locking screens (Option A) to prevent unauthorized access to active payroll sessions and ensuring a stable power supply (Option D) via Uninterruptible Power Supplies (UPS) to prevent data corruption during power surges or outages. Protecting the physical hardware is just as important as protecting the software via passwords and encryption in a payroll environment.
