A denial of service attack's intent is to deny legitimate users access to a resource such as a network, server etc. SYN attack works by flooding the victim with incomplete SYN messages. This causes the victim machine to allocate memory resources that are never used and deny access to legitimate users SYN Flood DOS attacks involves sending too many SYN packets (with a bad or random source ip) to the destination server. Most webservers now a days use firewalls which can handle such syn flood attacks and moreover even web servers are now more immune SYN flood - sends a request to connect to a server, but never completes the handshake . Continues until all open ports are saturated with requests and none are available for legitimate users to connect to. Other DoS attacks simply exploit vulnerabilities that cause the target system or service to crash
