ITPEC FE Morning October 2021 Question 39
ITPEC FE Morning October 2021 — Question 39 of 80
Virus vs Other Malware — identify malware that embeds in programs and copies itself.
A virus attaches to a host program and replicates by inserting copies into other programs.
Why not others:
- (a) Backdoor — hidden access point bypassing authentication; does not replicate
- (b) Trojan horse — disguises as legitimate software; does not self-replicate
- (d) Worm — self-replicates but spreads independently without needing a host program
Key rule: Virus = needs a host program to spread. Worm = spreads on its own across networks.
