If a security guard is responsible for regulating entry to premises, which option best describes their role?

The role of a security guard in regulating entry to premises is best described by monitoring and controlling access. This involves verifying the identity of individuals attempting to enter, ensuring that only authorized personnel gain access, and maintaining the safety and security of the premises. This responsibility encompasses checking identification, managing visitor logs, and potentially screening for prohibited items, all aimed at protecting the property and ensuring that operations run smoothly.

While watching for security threats is a part of a security guard's duties, it is a broader role that goes beyond just observing. Providing entertainment for visitors and assisting individuals with inquiries do not align with the primary responsibilities of a security guard whose primary focus is on the security and access management of the site they are assigned to. Thus, monitoring and controlling access effectively captures the essential function of a security guard in this context.
