A three-way handshake is primarily used to create a TCP socket connection to reliably transmit data between devices. For example, it supports communication between a web browser on the client side and a server every time a user navigates the Internet. As soon as a client requests a communicati...
A TCP SYN Flood attack seeks to exploit the TCP three-way handshake mechanism, which is foundational for establishing connections inTCP/IPnetworks. The handshake involves three steps: A client sends a SYN (synchronize) message to a server, indicating a desire to establish a connection. The serve...

Open: Occurs when the WebSockets connection is established between client and server using the initial handshake. Message: Happens during the entire open phase of the connection. Client and server can both push messages using the same bidirectional TCP connection. Messages can take several forms as...
Establishing a TCP connection: the three-way handshake Establishing a TCP connection requires that both the client and server participate in what is known as athree-way handshake. The process can be broken down as follows: A client sends the server a SYN packet—a connection request from its ...
The process of PCEP session establishment is as follows: A PCC initiates a TCP request to a PCE. After performing a three-way handshake, they establish a TCP connection. The PCC and PCE exchange PCEP Open messages to negotiate a session. Once the negotiation succeeds, they exchange PCEP Keep...
As what I know, an open TCP scan is just a normal TCP 3-way handshake followed by RST. It is detectable because the target will log this connection. For the half-open TCP scan, it is defined as "stealth". The explanation is that only a SYN packet is se...
Three-way handshake in TCP with ACK Many types of messages are sent over networks based on TCP. For example, SYN (synchronization) is used to initiate and establish a connection and to synchronize sequence numbers between devices in the network. The receiving station sends ACK to confirm to th...
A three-way handshake (TCP/IP handshake) is the first three interactions between a client and a server trying to establish a TCP connection. These initial interactions are essential in making a secure connection. At this phase, both client and server will agree on parameters that they will use...
