The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.

The influence of Russia has had a significant impact on the 2016 election in the United States, but this kind of war is still a new type of war. There is no Geneva Convention or treaty that can guide any country how to interpret these attacks or respond accordingly.

DDoS (Distributed Denial of Service) is a kind of attack that is difficult to prevent in DoS family. The attacker first controls a large number of broilers and then sends a large number of requests to the target server, resulting in the target server being unavailable. Here we cannot help asking how the attacker obtained a large number of broilers. Attackers will implant some malicious codes into some APP or websites. For example, when users use this APP or website, they will automatically request this website. If there are many active users of this APP or website, then this website will receive many inexplicable requests. This requires us not to browse some unknown websites and download APP from unknown sources in the process of surfing the Internet at ordinary times.
