Which term describes a technique intruders use to make network or internet transmissions appear legitimate to a victim computer or network?

• A. Flooding
• B. Spoofing
• C. CAM
• D. DRM

Answer: (B)

Spoofing is the technique where an attacker pretends to be a trusted source, crafting transmissions that look legitimate to the victim’s device or network. By forging identifiers such as the source IP address, MAC address, or email header, the attacker aims to bypass trust checks and get the victim to accept or act on the communication. This can enable things like intercepting traffic (man-in-the-middle), phishing, or data exfiltration because the system believes the data is coming from a legitimate, trustworthy source. Flooding would overwhelm a network with traffic and doesn’t involve making transmissions appear legitimate. CAM (Content-Addressable Memory) relates to fast lookups in networking hardware rather than deception. DRM (Digital Rights Management) governs how content is used and isn’t about impersonating sources.
