Final answer:
A honeynet is a fake network designed to attract cyber intruders, allowing network administrators to study their attack methods in a controlled and safe environment without risking real data or systems. It is the correct answer to the student's question about a system designed with unpatched vulnerabilities and false data to tempt attackers.
Step-by-step explanation:
The correct answer to the student's question is B. Honeynet. A honeynet is a type of decoy system designed to appear as a legitimate part of a network but is actually isolated and monitored. It serves the purpose of attracting hackers and cyberattacks, allowing administrators to study their methods and patterns without risking real data or systems. Typically, honeynets are networks of virtual machines, each configured with vulnerabilities and fictitious data to make them appear as valuable targets. Unlike the IDS (Intrusion Detection System), which detects and reports breaches, or the concept of a padded cell, which isolates a detected intrusion attempt within a controlled environment without the intruder's knowledge, a honeynet deliberately seeks to be probed and attacked to gain intelligence. The term 'pseudo flaw' does not correspond to a recognized security solution or system.
