Cisco Exam 200-201 Topic 5 Question 109 Discussion

Actual exam question for Cisco's 200-201 exam

Question #: 109
Topic #: 5

What is the difference between statistical detection and rule-based detection models?

ARule-based detection involves the collection of data in relation to the behavior of legitimate users over a period of time

BStatistical detection defines legitimate data of users over a period of time and rule-based detection defines it on an IF/THEN basis

CStatistical detection involves the evaluation of an object on its intended actions before it executes that behavior

DRule-based detection defines legitimate data of users over a period of time and statistical detection defines it on an IF/THEN basis

Show Suggested Answer

Suggested Answer: B

Statistical detection involves collecting data over time to define what is considered normal behavior or legitimate data for users or systems. It then uses statistical analysis to identify abnormal behavior that could indicate a security incident. Rule-based detection uses predefined rules or patterns that are based on known threats or vulnerabilities - it operates on an IF/THEN basis where if certain conditions are met then an alert is triggered.Reference:=Cisco Cybersecurity Operations Fundamentals

Exactly. It's all about the approach to analyzing and detecting anomalies in data.

So, statistical detection is more proactive in identifying potential threats, while rule-based detection is more reactive?

I agree. Statistical detection focuses on evaluating behavior before execution, while rule-based detection collects data over time.

I think the difference lies in how they define legitimate data.

I'm going with B. Anything involving IF/THEN statements just screams 'rule-based' to me. But who knows, maybe the correct answer is 'all of the above and none of the above' - that's the kind of mind-bending logic these exams love.

This question is a real head-scratcher. Maybe the answer key is just a random number generator - that would be a real statistical detection model!

D is what I would choose. Rule-based detection defines legitimate data over time, while statistical detection uses conditional logic.

C seems more accurate to me. Statistical detection evaluates an object's intended actions before it executes, rather than just looking at past behavior.

I think B is the correct answer. Statistical detection defines data over time, while rule-based detection is more IF/THEN based.

I think B is the correct answer. Statistical detection uses data analysis to define legitimate user behavior, while rule-based detection uses predefined rules to detect anomalies.
