Nebraska Security Guard State Practice Exam

Access control can be defined as

1. The control of a person’s freedom of movement through a designated area while taking away the freedom of movement of unauthorized people attempting to gain entry

2. The allowance of access to any person entering a given premise

3. The allowance for movement of authorized people and materials through protected areas, while detecting, delaying, and/or preventing the movement of unauthorized people or materials

4. A system of randomly controlling the number of people entering a premise at the sole discretion of the security guard

The correct answer is: The allowance for movement of authorized people and materials through protected areas, while detecting, delaying, and/or preventing the movement of unauthorized people or materials

Access control, in the context of security and safety, refers to the selective restriction of access to a place or resource. This means allowing for the free movement of authorized people and materials through protected or restricted areas. It also includes detecting, delaying, and/or preventing the movement of unauthorized or unapproved people or materials. Hence, option C is the correct answer as it accurately defines these two core aspects of access control. The aim of implementing access control is to provide protection from unauthorized entries or actions, be it for a physical location (like a building, a room within a building, a gated community, a country border, or a different kind of geographic boundary) or for a digital resource (like a network or a system portal). The implementation of access control may involve various methods and technologies, such as the use of mechanical locks and keys, card readers, biometric scanners, electronic access control systems, or a combination of strategies as needed.
