Index Minimum Security Low Security Level Medium Security Level High Security Level Maximum Security Physical security is necessary for an organization to protect its assets. However, no security system is completely safe. Physical security protects the organization's personnel, information, physical resources, systems, facilities, and assets (Harris, 2013). Any developed system can be bypassed. Organizations always focus on technological and administrative controls and therefore intrusions may not be discovered immediately (Oriyano, 2014). If a system is developed to protect an organization from threats, it should have some weak links; for example an alarm system or a perimeter wall. In case the developed security system is unable to provide complete threat protection, it should delay the threat until the system can be updated. The various parts of a security system cannot achieve the desired objective if not integrated in the right proportions. The lack of standards in security systems often misleads security system personnel into believing that they are providing higher-level security systems for their organization than is often the case. The team should identify key performance indicators (KPIs) to augment the safety program (Santander, 2010). KPIs should be monitored timely, quarterly, in the current year and across years (Wailgum, 2005). Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

These unwarranted external activities are described as emanating outside the scope of the minimum security system and could range from a basic intrusion to an armed intrusion. From the definition, a minimum security system could include very basic physical security systems such as basic doors and windows made with regular locks. The most appropriate example for a place with a minimal security system is an average American home. Low-level security Low-level security systems are security systems that thwart and detect some unauthorized external activities. Once basic physical security barriers and locks have been developed, additional barriers are always added in the implementation of the security system, such as reinforced doors, gates, high-security locks, and window grills and grills. Additionally, a basic lighting system which could be nothing more complicated than normal security lighting systems on windows and doors and a normal security alarm system which would be an unattended device at the site of an unauthorized intrusion which provides detection capabilities and audible alerts. Some of the places that implement low-level security systems include warehouses, retail stores, and small business premises. Medium Security Medium security systems are security systems that thwart, detect, and evaluate some unauthorized internal activities and most unauthorized external activities. Some of these activities could be simple shoplifting or sabotage intentions. As a security system is developed to a medium security level, the minimum and low level uses previously developed in the system areextended with obstruction and detection capabilities and threat assessment capabilities. To achieve a medium level of physical security, it is important to: Use an advanced intruder security alarm system that emits audible alerts at a remote, manned location. Develop a perimeter fence beyond the boundaries of the location protected from unauthorized intrusion attacks and place advanced physical security barriers such as intrusion-resistant fences that are no less than eight feet high and extended with coaxial strands of barbed tape or barbed wire at the fence perimeter, or place guard dogs on the perimeter protection site. Deploy unarmed guards (with primary training) equipped with basic communication capability (e.g., collaborate by telephone) with off-site agencies. Medium security systems are often used in giant industrial manufacturing plants, in some large warehouses, bonded warehouses and armories. High-Level Security High-level security systems are security systems that thwart, detect, and evaluate most unauthorized internal activities and most unauthorized external activities. After the previously mentioned measures are incorporated into the system, high-level security is achieved with the addition of the following: State-of-the-art equipment installed. Closed-circuit television (CCTV) with state-of-the-art components and installations. A system of Perimeter alarm, remotely monitored, at or near high security physical barriers. High security lighting, which at a minimum provides at least 0.02 foot candles of light around the entire facility. Highly trained armed guards or unarmed persons who have been selected for employment and who are equipped with advanced means of communication, such as dedicated telephone lines, two-way radio links with the police, and duress alarms. Controls designed to limit access to or within a facility to authorized personnel, for example by using access control and/or biometrics. Formal plans prepared with the knowledge and cooperation of the police dealing with their response and assistance in case of specific contingencies in the protected site. Varying degrees of coordination with local law enforcement authorities. Conducted annual assessment or safety audit. Examples of high-level security sites include some prisons, defense contractors, pharmaceutical companies, and sophisticated electronics manufacturing sites. After the previously mentioned measures are incorporated into the system, high-level security is achieved by adding the following: Addition of advanced equipment. CCTV with progressive parts and installation. An alarm at the perimeter fence, monitored remotely, at the high-security physical location. Ultra-high security lighting, with at least 0.02 foot candles of lighting throughout the entire location. Guards with advanced training or unarmed guards who have been screened prior to employment possess advanced communications skills. Controls developed to limit access within a facility to non-approved personnel, such as biometric checks. Formal security plans response in case of any unexpected incidents. Various levels of engagement with law enforcement authorities. Annual security assessment or audit carried out. High level security is often used in some prisons, pharmaceutical companies and advanced electronic industries. Maximum securityThis system is intended to prevent, detect, evaluate and neutralize all unauthorized external and internal activities. In addition to the measures already mentioned, it is characterized by: A refined alarm system.
