Fencing, locks, access control cards, biometric access control systems, and fire suppression systems are examples of hardening methods. These can either be employed individually or in combination to provide an adequate level of security for airports.
Locks include traditional key-based locks and lockers, which can either be bolted or chained to furniture or vehicles, respectively. They may also include magnetic locks, which require a special key to open them from outside the door, and electronic locks, which use a computer chip to release a latch mechanism when powered by the correct code. Locks are used to protect items such as luggage, vehicles, and equipment from theft or vandalism.
Access control cards are used in place of keys to allow only authorized people to enter a room or area. Cards can be either magnetic or optical. Magnetic cards contain small strips of metal that retain their shape even after being bent through a large angle. Optical cards use light beams projected into your eyes to verify your identity. This type of card requires sufficient light for you to see where you are going inside the airport.
Biometric access control systems measure personal characteristics such as hand geometry, palm patterns, and iris patterns to identify individuals. This method is commonly used for military applications where multiple personnel must be granted access to restricted areas.
Physical protections include the following:
Physical security entails the employment of various layers of interconnected systems, such as CCTV monitoring, security guards, defensive barriers, locks, access control, perimeter incursion detection, deterrent systems, fire protection, and other systems meant to safeguard people and property. Physical security is used to protect buildings, equipment, and devices from damage or theft.
CCTV surveillance is the most common form of physical security today. It can be found in almost all types of businesses and institutions, including schools, hospitals, government offices, museums, churches, libraries, and power plants. Its wide use is due to its effectiveness in capturing crime scenes on tape for later review by police investigators. Cameras can also provide evidence that helps secure criminal convictions.
Security guards help protect facilities by providing an additional layer of deterrence for would-be criminals. They often work with video cameras to monitor activities in high-risk areas where crimes may occur. Security guards can also report suspicious behavior to authorities or perform other tasks as needed.
Barriers are used to restrict access to certain areas. These can be actual physical structures such as walls or fences, or they can be electronic sensors such as loop detectors or radio frequency identification (RFID) tags. Barriers can be used alone or in combination with others methods such as armed response teams or biometric scanning devices.
Methods of deterrence
What steps should you take to ensure a building's physical security? Install controlled access to any place inside the building other than the lobby (such as locking doors and security checkpoints). - All authorized workers should be required to wear identification when within the building. This includes delivery people, repair people, and others who may come into contact with confidential information or property. - Keep valuables out of sight by storing them in a safe or secure lockable container. Dispose of keys to any locks that are not on display. Avoid hiding keys under furniture or in walls. These places can be used by thieves to find additional keys that they can sell or give away.
Thieves generally work in groups called "cracks". A crack team can break into hundreds of buildings during their career. They often use tools such as wire cutters, drill machines, and laser beams to open doors and windows without making a sound. They may even bring their own doorways for easy entry.
Thieves look for things like easy-to-open doors, mailboxes that are not protected by a keypad, and vacant apartments or offices. If you what to make an office or apartment building more secure, here are some suggestions: - Use dead bolts instead of only locks on doors. - Install peepholes in all door frames so people can see who is at the door without opening it.
