Which critical infrastructure do private security typically guard?

Private security plays a significant role in protecting various types of critical infrastructure, with malls and schools being key areas where their presence is commonly required. Malls are high foot-traffic areas with significant retail activity, making them potential targets for theft, vandalism, and other security threats. Private security personnel are employed to ensure the safety of shoppers, manage crowds, and respond to incidents.

Similarly, schools require a secure environment for students, staff, and visitors. With increasing concerns about safety in educational settings, private security personnel often work to prevent unauthorized access, monitor behavior, and respond quickly to any emergency situations.

This versatility in guarding both malls and schools highlights the integral role private security plays in maintaining safety in community spaces that are frequented by the public. The other options are limited in scope or specificity, as private security can operate in various other sectors beyond government buildings, airports, or public transportation systems.
