A security administrator wants to discover zero-day attacks before they can be used on the company’s network. Which of the following can the administrator use to accomplish this task?
Answer: B
A honeypot is a decoy system designed to attract attackers and analyze their behavior. Since it mimics a legitimate network environment, attackers might unknowingly exploit unknown (zero-day) vulnerabilities in the honeypot before targeting real systems. Security administrators can then study these attacks, identify new threats, and develop countermeasures before they impact the actual network.
