The 10 TCP header fields are as follows: Source port –The sending device’s port. Destination port –The receiving device’s port. Sequence number –A device initiating a TCP connection must choose a random in
TCP provides reliable delivery due to the process of error detection, in which TCP retransmits and reorders packets after they arrive. However, it can introducelatencyin a TCP stream. UDP on the other hand doesn't retransmit data. Highly time-sensitive applications, such as voice over IP, st...

This way, a hop sequence is built to trace the MTAs handling the message. SMTP has an asymmetrical mechanism that allows many clients to interact with one server, using the TCP/IP suite. Email protocols are sets of rules designed to organize the exchange of information between email clients ...
In case of network layer attacks (e.g.DDoS attacksthat don’t require a full three-wayTCP connection), attackers can use IP spoofing to make it appear as though they are connecting via a different IP address. This enables them to bypass blacklisting while obscuring their identity. It can ...
learning the pattern of TCP sequence numbers that the computer generates. He flooded the computer with SYN requests from spoofed IP addresses that were routable but inactive. The computer could not respond to the requests, and its memory filled with SYN requests. This technique is known asSYN ...
For example, in a network protocol like transmission control protocol (TCP), sequence numbers are used to keep track of the order of transmitted data. Each time a segment of data is sent, the sequence number is incremented to ensure that the data is received and processed in the correct ...
IS-IS packets are classified into Hello protocol data units (PDUs), link state PDUs (LSPs), and sequence number PDUs (SNPs). Hello PDU Hello packets, also called IS-to-IS Hello PDUs (IIHs), are used to set up and maintain neighbor relationships. On a broadcast network, Level-1 IS-IS...
(tcp) for reliable and ordered delivery of packets, and the user datagram protocol (udp) for faster but unreliable transmission, often used in real-time applications. what is the concept of packet sniffing? packet sniffing refers to the process of capturing and analyzing network packets. by ...
system on that end. The server is the physical hardware on the other end that runs the website you're trying to access. HTTP is a go-between, mediating between the client and the server, via TCP and IP. The entire exchange from the first request to the last, is called anHTTP ...
