ITPEC FE Morning April 2023 Question 40

A URL that allows access without the normal authentication — a back door is a hidden entrance that skips the official access procedure.

A back door lets someone into a system without the usual checks: a secret URL, a hidden account, or a program an intruder installs to return later. It may be left by a developer for maintenance or planted by an attacker, and is often hidden by a rootkit.

Answer (c)

Why not others:

• •(a) — a switch port that copies traffic for inspection is a mirror port, a monitoring feature.
• •(b) — a tool that finds open TCP ports and identifies the services behind them is a port scanner.
• •(d) — overflowing a memory area with an overly long string is a buffer overflow attack.

Key rule: A back door is an entry point that bypasses authentication; do not confuse it with tools that find weaknesses (port scanners), watch traffic (mirror ports) or attacks that exploit bugs (buffer overflow).
