What type of security tool has Jack deployed that simulates a vulnerable system?

A honeypot is a security tool designed to mimic a vulnerable system, intentionally exposing weaknesses to attract malicious actors. The primary purpose of a honeypot is to gather intelligence on attackers, learn their methods, and improve security measures without risking actual production systems. By simulating a vulnerable environment, honeypots can entice attackers to engage with the system, allowing security professionals to monitor their actions and understand their tactics, techniques, and procedures.

In contrast, a decoy server may also reveal vulnerabilities but often serves a different purpose, such as diverting attention from actual systems or creating confusion among attackers. A sandbox, on the other hand, is a controlled environment primarily used to run and analyze untrusted code or applications safely without risking the security of the host machine. Finally, a firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules, providing a barrier against unauthorized access. Thus, while all of these tools can contribute to security, a honeypot specifically focuses on simulating a vulnerable environment to study attacker behavior.
