Key cards at a bank are not tied to individuals, but rather to organizational roles. After a break in, it
becomes apparent that extra efforts must be taken to successfully pinpoint who exactly enters secure
areas. Which of the following security measures can be put in place to mitigate the issue until a new key
card system can be installed?

A.
Bollards

B.
Video surveillance

C.
Proximity readers

D.
Fencing

Explanation:
Video surveillance is making use of a camera, or CCTV that is able to record everything it sees and is
always running. This way you will be able to check exactly who enters secure areas.
Incorrect Answers:
A: Bollards are physical barriers designed to keep large items, such as vehicles from breaching a perimeter
and individuals will still be able to enter through the bollards.
C: Proximity readers works with cards/identity cards, but in this case a new key card system is to be
implemented and is at the present moment not an option.D: Fencing is used as a perimeter security measure and in this case the problem is on the inside of the
bank. You also cannot keep out clients with a fence.
