Which of the following are additional terms used to describe knowledge-based IDS and behavior based IDS?

The correct answer is A. signature-based IDS and statistical anomaly-based IDS, respectively. Knowledge-based IDS is synonymous with signature-based IDS - both rely on a database of known attack patterns. Behavior-based IDS is synonymous with statistical anomaly-based IDS - both establish a baseline of normal activity and flag statistically significant deviations. The pai

Explanation

Knowledge-based IDS is synonymous with signature-based IDS - both rely on a database of known attack patterns. Behavior-based IDS is synonymous with statistical anomaly-based IDS - both establish a baseline of normal activity and flag statistically significant deviations. The pairing in choice A correctly maps both terms. The other choices either use invented terms ('dynamic anomaly-based', 'motion anomaly-based') or swap the mapping incorrectly.
