ITPEC IP April 2024 Question 45
ITPEC IP April 2024 — Question 45 of 100
A backdoor is a hidden or unauthorized access method left in a system so normal authentication or controls can be bypassed later. After an intrusion, an attacker may alter software, create a secret account, install a remote-access component, or change configuration so future access is easier and more persistent.
Answer (b)
Why not others:
- (a) Tapping intercepts communications or signals to eavesdrop on information
- (c) Phishing deceives a victim into revealing information or taking an unsafe action
- (d) Port scanning probes network ports to discover reachable services and possible attack surfaces
Key rule: A backdoor provides concealed re-entry or bypass access; scanning discovers entry points, phishing obtains access through deception, and tapping observes communications.
