Setting up a honeypot is the correct answer because it is a decoy system or network designed to attract attackers and study their behavior, tactics, and techniques. This allows the security team to proactively understand threats and improve their defenses. Network segmentation, although beneficial for reducing the attack surface, does not fit the objective of attracting and observing an attacker. Patch management is a preventative strategy focused on remediating vulnerabilities rather than actively engaging with threats. Installing a firewall is also a preventative measure that does not provide interaction or learning opportunities with attackers.
