Which of the following accurately describes cache poisoning?

• A. An insider threat exploiting privileged access
• B. Manipulating DNS responses with false information
• C. Using a virus to gain administrative rights
• D. Creating fake websites to capture user input

Answer: (B)

Cache poisoning specifically refers to a technique used to manipulate the cache of a DNS resolver by injecting false DNS information. This can mislead users into visiting malicious sites instead of the intended legitimate ones. By providing false responses that are then cached, attackers can redirect traffic and potentially capture sensitive data or disrupt services. This manipulation exploits the trust that systems place in cached DNS responses, and successful cache poisoning can lead to various security vulnerabilities, including phishing attacks or denial-of-service situations. Overall, choice B effectively encapsulates the essence of what cache poisoning is and how it operates within the domain of network security.
