TCP Reset Definition: TCP Reset is a control message sent in response to an inconsistent communication state or to terminate an active connection, allowing both ends to clear resources and reset the connection.
TCP reset, also known as a TCP RST, is a control message sent in the Transmission Control Protocol (TCP) to abruptly close an existing connection. It is used to terminate a connection when an abnormal or unauthorized event is detected, enabling one side of the communication to notify the other that the connection should be reset. This process helps to ensure network security and stability by promptly ending communication sessions that may pose a security risk.
