What are the attack methods of Ddos?
Article Introduction:The three attack methods of DDoS are: 1. SYN/ACKFlood attack; mainly by sending a large number of SYN or ACK packets with forged source IPs and source ports to the victim host, causing the host's cache resources to be exhausted or busy sending response packets to cause rejection. Serve. 2. TCP full connection attack; it is designed to bypass conventional firewall inspections. 3. Script attack; characterized by establishing a normal TCP connection with the server and constantly submitting queries, lists and other calls that consume a large number of database resources to the script program. The biggest headache for websites is being attacked. Common server attack methods mainly include the following: port penetration, port penetration, password cracking, and DDOS attacks. Among them, DDOS is currently the most powerful and the most
