Which of the following are valid Network Traffic Analysis detectors in vDefend ATP? (Select all that apply)

Full set: 75 questions
Answer options
A: DNS tunneling Correct answer
B: Unusual traffic pattern Correct answer
C: Password brute force
D: Vertical port scan Correct answer
Correct Answer:
A. DNS tunneling; B. Unusual traffic pattern; D. Vertical port scan
Explanation

VMware vDefend Advanced Threat Prevention (ATP), formerly NSX ATP, includes Network Traffic Analysis (NTA). NTA uses unsupervised machine learning to establish a baseline of normal network behavior and then detects anomalies. Its detectors are designed to identify suspicious patterns indicative of threat activity. This includes detecting DNS tunneling, recognizing unusual traffic patterns that deviate from the baseline, and identifying scanning activities like vertical port scans.

Why Incorrect

C. Password brute force: While the resulting traffic might create an anomaly, password brute force is typically an application-layer attack detected by specific IDS/IPS signatures or log analysis, not a primary NTA behavioral detector.
