BMIS – L1 – SA – Q18.1 – IS Security

Information should be easily accessible when it is needed, but it is also important to keep data secure. Which ONE of the following is NOT a method of keeping data secure?

A   WANs

B   Back-up files

C   Anti-virus software

D   Encrypted data

A

Explanation:
A WAN (wide area network) is a term used to describe a computer system that is spread over a large geographical area, facilitating communication between devices but not inherently securing data. Back-up files ensure data recovery, anti-virus software protects against malware, and encrypted data safeguards information by making it unreadable without a key. Thus, WANs are not a method for keeping data secure, making A the correct answer.
