SYN flag
Sequence number (32 bits) has a dual role: If the SYN flag is set (1), then this is the initial sequence number; If the SYN flag is clear (0), then this is the accumulated sequence number of the first data byte of this segment.
ICMP
The Internet Control Message Protocol (ICMP) is one of the main protocols of the internet protocol suite. It is used by network devices, like routers, to send error messages indicating, for example, that a requested service is not available or that a host or router could not be reached.
SYN request
Connection request over TCP. If a packet containing a SYN flag is sent, this means that a client is requesting a server for a connection. The server in turn must respond to the client with a packet that contains SYN-ACK flag.
DDoS attack
A DDoS attack (Distributed Denial of Service attack) is a complex of actions aimed at fully or partially rendering an online resource unavailable to its intended users. Almost any online resource can be targeted: a website, a game server, or a public resource.
ACK-flag
ACK-flag is a flag in TCP segment. It's indicates that the Acknowledgment field is significant. All packets after the initial SYN packet sent by the client should have this flag set.
TCP packet
A network packet is a formatted unit of data carried by a packet-switched network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream.
Server
Server is a computer program or a device that provides functionality for other programs or devices, called "clients"
