ARP, DNS, and IP are examples of which security concept?

• A. Spoofing methods
• B. Encryption standards
• C. Authentication protocols
• D. Access control models

Answer: (A)

Spoofing methods involve deceiving a system by forging information such as address mappings or identifiers. ARP spoofing manipulates the local ARP table to make devices associate an attacker’s MAC address with a legitimate IP, enabling interception or modification of traffic. DNS spoofing poisons DNS responses so users are directed to malicious hosts. IP spoofing forges the source IP in packets to appear as someone else, aiding impersonation or evasion of checks. These aren’t encryption standards, authentication protocols, or access control models. Encryption standards describe how data is encoded and protected, authentication protocols verify identity, and access control models govern who can access what. The common thread here is deception to misrepresent identity or direction of traffic, which fits spoofing techniques.
