Answer to Question #248842 in Computer Networks for gkat

Question

Describe a type scenario involving 2 computer Devices transferring a video file using an unsecured ftp connection where TCP three-way handshake is susceptible to vulnerability

Answer 1

Three-Way handshake is the process used in TCP/IP networks to establish connections between client and server devices. Both the client and the server must exchange synchronization and acknowledgment packets before exchanging data for real time communication.

A possible scenario during video sharing using unsecured ftp between two devices where TCP handshake is prone attack is during synchronization and exchange of synchronization packets between the client and the server.

A possible man in the middle attack can be performed to intercept the packets exchange. The packets can be filtered to obtain acknowledgment packets used to establish a secure connection.

A possible denial of service attack can also be carried out in which clients and server are denied access to the service.
