Palo Alto Networks NetSec-Pro Exam - Topic 4 Question 2 Discussion

Actual exam question for Palo Alto Networks's NetSec-Pro exam
Question #: 2
Topic #: 4
[All NetSec-Pro Questions]

Which set of attributes is used by IoT Security to identify and classify appliances on a network when determining Device-ID?

Show Suggested Answer Hide Answer
Suggested Answer: B

IoT Security uses MAC address, device manufacturer, and OS information to identify and classify devices via Device-ID.

''IoT Security uses passive network traffic analysis to fingerprint devices based on the MAC address, manufacturer, and operating system to ensure accurate classification.''

(Source: IoT Security Device-ID and Classification)

These attributes provide a robust, manufacturer-agnostic method to fingerprint IoT devices.
