I'm studying for CISSP and had gotten this question wrong. I also found it and the correct answer online, but still don't understand the reasoning.
- Which of the following controls is not appropriate to prevent unauthorized people from entering a computer center?
a. Double-locked doors
b. Television monitors
c. Terminal IDs
d. Picture ID badges
- c. Logical access controls verify the terminal identification (ID) number and not a part of physical security. Logical access controls provide a technical means of controlling what information users can utilize, the programs they can run, and the modifications they can make. The other three choices deal with physical security, which is the right kind of control to prevent unauthorized people from entering a computer center.
First of all, what is the definition of "controls"?
Second, I thought b) would be the correct answer because TV monitors don't actually prevent anything by themselves.
By terminal IDs do they mean the username/password a person can login to a computer with? This certainly seems ambiguous because it could also refer to a serial number used for keeping track of physical assets, or some sort badge that shows the person is allowed in.
