Both fences and lighting increase the feeling of safety.
8. What is access control? Explain access control and its importance by using the concept of “defense in depth.”
In physical control, access controls are used to minimize the access of a particular group of people to a specific place or resource. They make sure only authorized users to have the right to use the resource. They are important as they keep the organization safe by controlling the movements. When several access controls at each security layer used, it is easy to detect who enters and leaves the organization.
9. Explain the role of guard forces in a physical security program.
Security guards have different responsibilities within an organization. To ensure physical security is high, they patrol the property to make sure that there is no intruder. Another role is to monitor the surveillance system to identify any unwanted movements in the premises. They inspect entry points in the compound together with the equipment and the buildings. Finally, they guard the entry points to give permissions to those entering and leaving the organization.
10. Explain the importance of fire prevention, detection, and control as part of an effective physical security program. What are some common fire protection systems?
Fire detection and prevention in organizations is crucial as it helps in reducing the spread of fire when it occurs. It also helps to contain the smoke,thus reducing damages to both people and property. Several different systems are design for fire protection. They include fire doors, dampers, fire floors, mortar coating, flame shields, and emergency exit lights.
Chapter Five
1. Describe the role of personal security in the protective function
