Each question is designed to challenge your understanding and reinforce key concepts. Here is a sample question to illustrate the quality and depth of this course:

Sample Question:
Which of the following best describes the primary purpose of a honeypot in a network security strategy?

A. To encrypt sensitive data transmitted over public networks
B. To detect and analyze malicious activity by luring attackers into a controlled environment
C. To enforce access control policies based on user roles and group membership
D. To automatically patch vulnerabilities in operating systems

Correct Answer: B

Explanation:
A honeypot is a decoy system or service intentionally set up to attract and trap attackers. It does not provide real services but mimics vulnerable systems to gather intelligence on attacker behavior, tools, and tactics. By observing interactions with the honeypot, security teams can identify emerging threats, understand attack patterns, and improve defensive measures without exposing production systems. Honeypots are not used for encryption, access control, or patching — these are functions of other security controls. This makes option B the only accurate description.
