Explanation:
Honeypots are computer systems that are expressly set up to attract and trap individuals who attempt to penetrate other individuals’ computer systems. The concept of a honeypot is to learn from intruder’s actions. A properly designed and configured honeypot provides data on methods used to attack systems. The data are then used to improve measures that could curb future attacks. A firewall is basically a preventive measure. Trapdoors create a vulnerability that provides an opportunity for the insertion of unauthorized code into a system. Traffic analysis is a type of passive attack.
