200-201 Question 119
Single answerA cybersecurity analyst notices unusual traffic on the network, where data packets from a banned application are being encapsulated within HTTP packets to bypass the organization's firewall restrictions. What type of tunneling technique is most likely being used in this scenario?
- A
VPN tunneling
- B
IPSec tunneling
- C
Protocol tunneling
- D
HTTP tunneling
Show answer and explanation
Correct answer: D
Explanation
The scenario describes a technique where data from a restricted application is encapsulated within HTTP packets to evade firewall detection. This is a common use case of HTTP tunneling, which is often employed to bypass network restrictions by disguising restricted traffic as legitimate HTTP traffic.
- A. Incorrect.
VPN tunneling is used to securely connect remote users to a private network, but this scenario describes a way to bypass restrictions, not create secure access.
- B. Incorrect.
IPSec tunneling is primarily used for encrypting and securing communication between endpoints, but it is not related to encapsulating data within HTTP packets.
- C. Incorrect.
Protocol tunneling refers to the general concept of encapsulating one protocol within another, but the question specifically describes HTTP as the tunneling protocol.
- D. Correct.
HTTP tunneling is the correct answer as it involves encapsulating data packets within HTTP requests to bypass network restrictions like firewalls.
