Chicago Security Guard PERC Practice Exam 2026 – Complete Prep Guide

A key responsibility of a security guard is to protect people and property from theft or harm. This fundamental duty encompasses a range of activities aimed at ensuring safety and security in various environments. Security guards serve as a visible deterrent to crime, monitor premises, perform regular patrols, and remain vigilant to detect and respond to any suspicious activities or emergencies.

This protective role is essential in safeguarding lives and assets, establishing a sense of security for individuals in a variety of settings, such as commercial properties, residential areas, and public spaces. The ability to effectively respond to incidents, manage conflicts, and enforce rules is also a vital aspect of their job, aimed at maintaining a secure environment for all.

The other options refer to specific tasks or roles that may be associated with particular types of security jobs but do not encompass the overarching responsibility that defines a security guard's primary function. For example, managing a security team or conducting investigations may be more suited for higher-level positions or specialized roles, while providing security for large events is just one aspect of security work, not the core duty itself.
