Which term describes the interception of packets during transmission between a client and server in a TCP or UDP session?

• A. Application Level Hijacking
• B. Network Level Hijacking
• C. Spoofing Attack
• D. Session Hijacking

Answer: (B)

Intercepting packets as they travel between a client and server happens at the network level. This involves eavesdropping on the data in transit or tampering with it as it moves through the network path, which is a network-layer concern and can occur regardless of any specific application. That’s why the term that best fits is network level hijacking. This differs from session hijacking, which is about taking over an already established session after authentication by exploiting or stealing the session identifier. It also differs from spoofing, which is about forging identities or data, and from application level hijacking, which targets the application layer rather than the network path.
