Flashcard 12 - N10-009 Network Security Flashcard Set for the CompTIA Network+

Spoofing is impersonation; poisoning is injecting false data.

Address Resolution Protocol (ARP) spoofing is a cyberattack in which an attacker sends fake ARP messages to associate their media access control (MAC) address with a legitimate IP address, tricking devices into sending data to them instead of the intended recipient. This allows the attacker to intercept, modify, or redirect network traffic. While the terms are often used interchangeably, spoofing refers to impersonation, while poisoning involves injecting false data to corrupt ARP tables.
