What is the purpose of a Honeypot in security?

A honeypot is designed primarily to deceive attackers while simultaneously gathering valuable information about their methods and techniques. By simulating a vulnerable system or service, a honeypot attracts potential attackers, allowing security professionals to observe their behaviors in a controlled environment. This information can then be used to enhance the overall security posture by understanding how threats exploit vulnerabilities, which can inform future defensive measures.

In the context of the other options, while a honeypot may seem to contribute to network security, it does not function as a defensive barrier against attacks, nor does it provide a secure environment for legitimate users. It is specifically set up to trick attackers and study their approaches rather than acting as a backup server. This focus on deception and investigation is what distinguishes a honeypot from other security measures.
