Which of the following statements is NOT true about cyber defense systems?

The statement that "none of the above" is true because all the preceding statements about cyber defense systems accurately reflect their functions and characteristics.

Honeypots are indeed designed to mimic legitimate components of a network, enticing attackers to interact with them so that their methods and intentions can be analyzed without compromising actual system data. This setup provides valuable insights into attack strategies and helps identify vulnerabilities within the network by observing attacker behavior in a controlled environment.

In addition, honeypots are effective tools for organizations seeking to bolster their cybersecurity posture. They allow security teams to study attack patterns and refine their defensive capabilities based on real-world exploitation attempts.

Intrusion detection systems (IDS), on the other hand, do have limitations. Many traditional IDS focus on identifying patterns of suspicious activity based on known threats and may not inspect the detailed contents of data packets unless they are specifically designed for deep packet inspection. Consequently, they primarily rely on predefined rules and traffic filtering mechanisms.

All of these statements collectively affirm the accurate representation of cyber defense systems, validating that the option "none of the above" is indeed the correct answer.
