Cisco Exam 200-201 Topic 4 Question 100 Discussion

Actual exam question for Cisco's 200-201 exam

Question #: 100
Topic #: 4

How low does rule-based detection differ from behavioral detection?

ABehavioral systems find sequences that match particular attach behaviors, and rule-based systems identify potential zero-day attacks.

BRule-based systems search for patterns linked to specific types of attacks, and behavioral systems Identify attacks per signature.

CBehavioral systems have patterns are for complex environments, and rule-based systems can be used on low-mid-sized businesses.

DRule-based systems have predefined patterns, and behavioral systems learn the patterns that are specific to the environment.

Show Suggested Answer

Suggested Answer: D

Rule-based detection systems operate using predefined patterns and signatures to identify known threats. These patterns are based on prior knowledge of attack methods and vulnerabilities.

Behavioral detection systems, on the other hand, analyze the normal behavior of a network or system to establish a baseline. They then monitor for deviations from this baseline, which may indicate potential threats.

Rule-based systems are effective at detecting known threats but may struggle with novel or zero-day attacks that do not match existing signatures.

Behavioral systems can detect unknown threats by recognizing abnormal activities, making them useful in identifying zero-day exploits and other sophisticated attacks.

Oh man, this one's a head-scratcher. I'm gonna go with D, just because the idea of rule-based systems being more rigid and behavioral ones learning the environment makes sense. Although, who knows, maybe the correct answer is actually 'All of the above, plus a dancing robot'.

Hmm, I'm torn between B and D. Both sound plausible, but I think D is the more accurate description of the key difference. Gotta love these tricky cybersecurity questions!

D is the correct answer. Rule-based systems have predefined patterns, while behavioral systems learn the patterns specific to the environment. This is a pretty straightforward distinction.
