Question 15

________ includes data processing and storage equipment, transmission and networking facilities, and offline storage media.

Accepted Answer

Information system hardware includes data processing and storage equipment, transmission and networking facilities, and offline storage media. Supporting facilities usually refer to facilities that support the physical operation of the hardware and infrastructure facilities usually refer to the physical structures and systems necessary for the operation of a community or organization. Physical facilities can refer to any physical structures, not necessarily specific to information systems.

Question 16

Physical security must also prevent any type of physical access orintrusion that can compromise logical security.

Accepted Answer

Physical security encompasses measures designed to prevent unauthorized physical access to a facility, building, or equipment. This includes traditional barriers such as locks, alarms, access control systems, and surveillance cameras. By preventing physical access or intrusion, physical security measures can help to safeguard against unauthorized access or breach of logical security, which refers to the protection of computer systems and data from unauthorized access, theft, or damage. Thus, the statement is true, and physical security is an essential component of an effective overall security strategy.

Question 17

Physical access control should address not just computers and other ISequipment but also locations of wiring used to connect systems, equipment and distribution systems, telephone and communications lines, backup media, and documents.

Accepted Answer

Physical access control should address all of these areas to ensure the security of information and systems.

Question 18

Physical security must prevent misuse of the physical infrastructurethat leads to the misuse or damage of the protected information.
