ITPEC FE Morning April 2023 — Question 40 of 80

Back Door — a hidden method to bypass normal authentication.

A back door is a URL, hidden account, or secret entry point that allows access to a system without going through standard authentication procedures (e.g., password login).

Why not others:
- (a) Port mirroring / packet sniffing — a LAN port on a switch used to capture and inspect network traffic

- (b) Port scanning — a tool that probes open TCP ports and identifies running services (e.g., nmap)

- (d) Buffer overflow — an attack that crashes a program by writing data beyond the allocated memory area

Key rule: A back door skips authentication entirely — it's about unauthorized access, not traffic inspection or memory corruption.
