Question 5

  • A Directory traversal
  • B Cross-site scripting
  • C Removable media
  • D Session hijacking
Reveal correct answer

Correct answer: C

Explanation

OBJ-7.2: Airgaps are designed to remove connections between two networks to create a physical segmentation between them. The only way to cross an airgap is to have a physical device between these systems, such as using a removable media device to transfer files between them. A directory traversal is an HTTP attack that allows attackers to access restricted directories and execute commands outside of the web server's root directory. Cross-Site Scripting (XSS) attacks are a type of injection in which malicious scripts are injected into otherwise benign and trusted websites. A session hijacking attack compromises the session token by stealing or predicting a valid session token to gain unauthorized access to the Web Server. A directory traversal, cross-site scripting, or session hijacking attack cannot by itself cross an airgap.
