Review Questions ch-9
1-What is physical security?
An aspect of information security that addresses the design, implementation, and maintenance of
countermeasure that protect the physical resources of an organization. The primary threats to physical security
are fires, gases, liquids.
2-What are the roles of IT, security, and general management with regard to physical security?
Are responsible for environmental and access security in technology equipment locations and for the policies
and standards for secure equipment operation. This includes access to server rooms, power conditioning and
server room temperature and humidity controls, as well as more specialized controls like static and dust
3-How does physical access control differ from the logical access control described in earlier chapter?
Some of the technology used to control physical access is also used to control logical access, including
biometrics, smart cards, and wireless enabled keycards, which can be used to control access to physical
locations, information assets, and information system resources. In fact, a secure facility can sometimes use its
natural terrain, local traffic flow, and surrounding development to enhance its physical security, along with
protection mechanisms, such as fences, gates, walls, guards, and alarms.
4-Define a secure facility.
A secure facility can sometimes use its natural terrain, local traffic flow, and surrounding development to
enhance its physical security, along with protection mechanisms, such as fences, gates, walls, guards, and
5-Why are guards considered the most effective form of control for situation that require decisive action
in the face of unfamiliar stimuli? Why are they usually the most expensive controls to deploy? When
should dogs be used for physical security?
Guard can evaluate each situation as it arises and make reasoned responses. Most guard have clear standard
operating procedures (SOPs) that help them to act decisively in unfamiliar situations. Guard dogs are useful
because their keen sense of smell and hearing can detect intrusion that human guards cannot, and they can be
placed in harm’s way when necessary to avoid risking the life of a human.
6-List and describe the four categories of locks. In which situation is each type of lock preferred?
