You are responsible for security at a hospital. Since many computers are accessed by multiple
employees 24 hours a day, 7 days a week, controlling physical access to computers is very difficult.
This is compounded by a high number of non employees moving through the building. You are
concerned about unauthorized access to patient records. What would best solve this problem?

A.
The use of CHAP.

B.
Time of day restrictions.

C.
The use of smart cards.

D.
Video surveillance of all computers.

Explanation:

Smart cards are a physical device that is needed to logon to a computer. This would mean that each
person would have to have a smart card
and a username/password to access any hospital computers.
Answer D is incorrect. If there is a security breach, video surveillance might help catch the
perpetrator, but it won’t prevent the breach.
Answer A is incorrect. Challenge Handshake Authentication Protocol, will not help prevent
unauthorized access to computers.
Answer B is incorrect. A hospital requires 24 hour a day access to patient data. Time of day
restrictions would not work.
