Physical security models and frameworks

Physical Security Models

The contemporary organizations extensively depend on security of their property in order to remain functional since there are delicate and valuable property, in terms of the data and physical property that are held within the organization at any given time. This implies that the physical security must be considered as one of the highest priority in any organization hence the features and how the physical security functions must be of impregnable quality as discussed below in order to keep the entire farm secure.

In matters of physical security, there are four critical considerations that are vital to consider according to Pagoria B., (2004) which are; areas on the perimeter of the business building, immediate area around the business building/environment, internal location of the business building, human factor. These four comprise the most crucial physical factors in physical security of any organization and is commonly referred to as the layered security model. It'd one of the preferred security models since it has multiple security layers before and after one has gained access to the concerned compound of an organization.

The areas around the business building and the immediate area around the business have various physical security measures put in place in this model and includes the electronic security system (ESS) as indicated by Taylor B., (2002) which would enable the detection of any intruder well before getting to the main perimeter wall. This is significant factor in this model since any impregnable security system relies on getting information about the intruder ahead of the intrusion. The intrusion detection systems (IDS) are critical in the early warning of possible security breach and they are monitored on an 24/7 schedule through the various CCTVs around the business to ensure maximum security.

Incase the cameras fail to pic the intrusion from a distance and the intruder gets to the perimeter wall successfully, the layered system is further equipped with seismic sensors which are equipped to detect the slightest movement very close to the perimeter wall. These are also accompanied by the electromagnetic sensors as well as the motion detectors for a layered threat detection and to provide redundancy. These layered physical security measure ensures synergy in the working of the security system, such that, if the motion sensors are tripped, the CCTV can rotate and zero in on the particular area where the motion sensor was tripped hence picking up the threat or detecting whether it was a false alarm.

On the immediate area around the business, there needs to be a string physical perimeter wall or a twelve feet high chain link fence. These can be layered by razor spiral at the top all around the perimeter wall. There could also be a second perimeter wall after the main one as well as security personnel patrolling the perimeter wall to handle any intrusions once detected. This type of perimeter wall works effectively in the layered security model since it gives the detection systems an inhibition backing to prevent intruders from accessing the business.

The intrusion can also come in the form of attempted access through the legitimate means like through the gate where the intruder will come in as any expected traffic. The layered physical security mode will have several choke points at the entry areas. There is the first heavy steel gate where vehicles stop for thorough and systematic checks. Electronic devices are used to check the vehicles and the visitors on foot are expected to go through metal detectors.
