Question

A company is experiencing overwhelming visits to a main web server. The IT department is developing a plan to add a couple more web servers for load balancing and redundancy. Which requirement of information security is addressed by implementing the plan?

(A) integrity
(B) scalability
(C) availability
(D) confidentiality

Answer 1

The answer is C) Availability.

Although the company is addressing scalability by adding more servers, the question is asking for security requirement. Therefore we need to choose one of the principles from CIA triad which includes confidentiality, integrity, and availability.

Integrity involves keeping the data accurate and confidentiality involves keeping the data between the sender and intended recipient(s). That being said, scalability and availability are the possible answers.

C) Availability is the best answer because it is part of the CIA triad.

Note: Another resource to look at for cyber security principles would be the Parkerian Hexad.
