I have monitored that some DoS attack which generates large bps(over 1Gbps) against my network. and I can see that all dos related packets are udp and icmp not tcp. In the point of view attacker, Is it impossible that generates lots of packets and large packets using tcp without 3 way handshake?
It's not impossible, but using stateless protocols like ICMP or UDP is a lot easier. Regards Ansgar Wiechers -- "All vulnerabilities deserve a public fear period prior to patches becoming available." --Jason Coombs on Bugtraq
