Security Fundamentals — Question 36

What is an example of non-propagating malicious code?

Answer options

• A. A back door
• B. A hoax
• C. A Trojan horse
• D. A worm

Correct answer: A

Explanation

A back door is a type of malicious code that allows unauthorized access without spreading to other systems. In contrast, a worm is designed to replicate and spread, while a Trojan horse pretends to be legitimate software but can still spread if executed. A hoax may mislead users but does not involve actual malicious code propagation.
