Characteristics of internal and external security systems


In the present times, both internal and external security form key aspects of the security architecture of an organization. It is extremely important to work on these aspects if a robust and impregnable security system is to be conceived. The aspects of internal and external security include frisking near the entry and exit points, securing boundaries, security planning, setting up control rooms, and recruiting professional security guards. The aspects highlighted here are also region-specific. For instance, security guards in Malaysia are known for their professionalism and expertise in ensuring both internal and external security coordination. 

Characteristics of internal and external security

Securing the boundaries

The first and foremost thing for ensuring a robust security infrastructure is to safeguard the boundaries of an establishment. In addition to this, the sidewalks, parking spaces as well as boundaries near the gateways should be safeguarded. There are two important ways through which we can safeguard the boundaries. The first way is related to physical security aspects and the second way is related to technological aspects. The physical aspect of security can be realized if we implant the fences and boundary walls with razor wires that are difficult to penetrate. In most of the cases where the use of razor wire is not feasible, we may also use alarming systems. We may also use the laser system to secure our boundaries but it is accompanied with higher cost. The technological aspect of securing the boundaries is to install CCTV cameras so that any suspicious activity is detected at the earliest. CCTV cameras that are equipped with artificial intelligence-powered technology alert the security authorities when the boundaries are breached.

Frisking near the entry and exit points

Access control is extremely important for safeguarding the entry and exit points. These two points can prove to be extremely crucial due to the higher density of men and the material that passes through them. As such, higher deployment of security forces near the entry and exit points can help in keeping an effective check on intruders. Security forces can not only regulate the movement through the entry and exit points but can also aid in internal operations whenever needed.

Internal security setup

Internal security is as important as external security. This is because even if intruders breached the external layer of security, we can still prevent the attack if our internal security setup is robust. Needless to mention, the internal security setup has to be such that it does not obstruct the functioning and other operations of an organization. At the same time, it should be ensured that the surrounding environs of the workplace are safe and secure. It is the responsibility of internal security forces to check the entry of unauthorized persons in and out of the internal premises.

Planning aspects

The planning aspects of a security system can be grouped into two broad categories. The first is called short term security planning and the second is called long term security planning. Short-term security planning includes brownfield development in the form of boosting the existing security mechanism and using new devices to detect security threats. The main aim of short-term security planning is to plug the loopholes in the security architecture. On the other hand, long-term security planning involves conceiving state of art infrastructure and a type of security system that is impossible to breach. The long-term aspects of security planning rely on green field development. This means that the security angle is taken into concern during the initial process of design and development of an establishment.


There are a large number of elements that are necessary for an integrated security service. Let’s examine some of these elements in detail. The first important element is related to the detection of various threats by intruders. It involves an elaborate alarming system that can sound and alert the authorities in case of the slightest breach. The second element is related to assessment. The assessment of the security infrastructure as well as its periodic maintenance is extremely important. The third element is used to fabricate a mechanism that can engage the intruder till the time the security forces arrive and neutralize the attack. Another element involves the activation of a response mechanism so that the intruders are prevented from achieving their objectives. The response mechanism has to be robust as well as devoid of any kind of delay.

The way ahead

The internal and external security systems can go a long way in determining the overall safety of an establishment. So, it becomes vital to work on both these aspects with novel technology aids.
