Security priority
The primary purpose of perimeter security is to detect, prevent, and delay illegal access to the assets enclosed by it and thus preventing any act of theft, vandalism, and sabotage. It acts as a boundary of separation between the outside world and the enclosed assets (Polyakov, 2017, October). It can either impede unauthorized persons or confine captives within the surrounded area. Perimeter security can either be in the form of manmade barriers or natural barriers. A dependable perimeter wall should combine various aspects such as the CCTV and the perimeter intruder detection system. Perimeter security systems have been embedded in different security strategies and settings. The type of perimeter security largely determines how it will be installed and used. The effectiveness of the three different types of perimeter walls differs depending on where they are used.
Perimeter security can either be physical, psychological, and technological. The physical perimeter security encloses the intended area entirely and makes it very hard for intruders to access the computer rooms, operation centers, and telecommunications rooms. In this scenario, physical controls such as fencing, guards, and locks are used to deter, deny and detect the penetration of the protected area by unauthorized persons (Draper et al., 2017). The psychological barriers deal with taming the possible intruders from accessing the protected area, for example, the use of electric fences. The technological barrier has adopted the usage of modern methods such as surveillance cameras and sensors. As such, technological perimeter security is the best of the three. This is because it allows for the coverage of more extensive areas which the other two types can hardly cover. Nevertheless, perimeter security has proved to be one of the most efficient methods of protecting assets.
