Physical security addresses the design, implementation, and maintenance of countermeasures that protect the physical resources of an organization. This means the physical protection of the people, hardware, and the supporting system elements and resources associated with the management of information in all its states: transmission, storage, and processing.
The primary threats to physical security include the following:
Inadvertent acts,
potential acts of human error or failure, potential deviations in quality of service by service providers, and power irregularities.
Deliberate acts - acts of espionage or trespass, acts of information extortion, acts of sabotage or vandalism, acts of theft, software attacks, and compromises to intellectual property; acts of God, forces of nature; technical failures technical hardware failures or errors and technical software failures or errors; and management failures
In the physical
environment, a potential act of human error or failure can be represented by an employee accidentally spilling coffee on his or her laptop computer. A compromise to intellectual property can include an employee without an appropriate security clearance copying a classified marketing plan.
A deliberate act of espionage or trespass could be exemplified by a competitor sneaking into a facility with a camera. Deliberate acts of sabotage or vandalism can be physical attacks on individuals or
property with the intent to sabotage or deface; deliberate acts of theft are perhaps the most common of these threats. Examples include employees stealing computer equipment, credentials, passwords, and laptops.
Acts of God include lightning hitting a building and causing a fire. Quality of service deviations from service providers, especially power and water, also represent physical security threats.
Technical hardware failures or errors and technological obsolescence both have common
examples in physical security.
What are the two possible modes of locks when they fail What implications do these modes have for human safety in which situation is each preferred?
Deliberate acts of sabotage or vandalism can be physical attacks on individuals or property with the intent to sabotage or deface; deliberate acts of theft are perhaps the most common of these threats. Examples include employees stealing computer equipment, credentials, passwords, and laptops.
The two most "critical factors" that would be affected would be the Sprinkler System and Air conditioning.
Examples of physical threats include: Natural events (e.g., floods, earthquakes, and tornados) Other environmental conditions (e.g., extreme temperatures, high humidity, heavy rains, and lightning) Intentional acts of destruction (e.g., theft, vandalism, and arson)
Both physical and logical access control is concerned with regulating who or what can access restricted areas, but logical access control refers to restricting virtual access to data, digital resources and computer networks, whereas physical access control restricts actual pedestrian footfall to buildings, rooms and ...
