Priorities and challenges for physical security leaders. More of your questions answered by our Experts. Likewise, when it comes to IT security, physical security is the foundation for our overall strategy. All of the technological systems that are employed to enhance physical security are useless without a security force that is trained in their use and maintenance, and which knows how to properly respond to breaches in security. Physical security should take into account your personnel, data and intellectual property and physical assets. R    Consequently, these physical threats could also compromise the integrity of operational systems and data. Physical security describes security measures that are designed to deny unauthorized access to facilities, equipment and resources and to protect personnel and property from damage or harm (such as espionage, theft, or terrorist attacks). An example would be decreasing the amount of dense, tall vegetation in the landscaping so that attackers cannot conceal themselves within it, or placing critical resources in areas where intruders would have to cross over a wide, open space to reach them (making it likely that someone would notice them).

Alarm systems work in tandem with physical barriers, mechanical systems, and security guards, serving to trigger a response when these other forms of security have been breached. Physical security describes measures designed to ensure the physical protection of IT assets like facilities, equipment, personnel, resources and other properties from damage and unauthorized physical access. [10] The introduction of low-voltage LED-based lighting products has enabled new security capabilities, such as instant-on or strobing, while substantially reducing electrical consumption[11]. The simple method for this is through the use of physical barriers and signs. Physical security measures are taken in order to protect these assets from physical threats including theft, vandalism, fire and natural disasters. If such a barrier aligns with a fire compartment as part of building code compliance, then multiple threats must be defeated simultaneously, which must be considered in the design. In the reconnaissance phase prior to an actual attack, some intruders will test the response time of security personnel to a deliberately tripped alarm system. [17][18][19], Access control methods are used to monitor and control traffic through specific access points and areas of the secure facility. by security guards and police).
