Matching Cybersecurity Terms: Detailed Explanation

To correctly match List - I with List - II, we analyze each term and its definition:

• A. Trojan: A Trojan is a type of malware that disguises itself as legitimate software. Once installed, it can perform malicious actions. Definition IV describes this perfectly: "A malware that looks like a legitimate software and once it tricks a user into installing it, it acts pretty much like a virus or worm." Therefore, A - IV.
• B. Cookie: A cookie is a small piece of data stored on the user's computer by the website they visit. Definition III matches this: "A small file or data packet, which is stored by a website on the client's computer." Therefore, B - III.
• C. Spyware: Spyware is software that secretly gathers information about a user and transmits it to an external entity. Definition II accurately describes this: "Records and sends the collected information to an external entity without the consent or knowledge of a user." Therefore, C - II.
• D. Firewall: A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Definition I defines this: "A network security system designed to protect a trusted private network from unauthorized access or traffic originating from an untrusted external network." Therefore, D - I.
