The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.

For easier management, We can also create custom chains in a table, Place the rules set for an application in this custom chain, But custom links cannot be used directly, It can only work if it is called as an action by a default chain. We can imagine that, Custom chain is a relatively "short" chain. The rules on this "short" chain are all formulated for an application program. However, this short chain cannot be directly used, but needs to be "welded" on the default definition chain of IPTables before it can be used by IPTables. This is why the default definition "chain" needs to refer to "custom chain" as "action". This is a later remark. We will talk about it later. We can understand it more clearly in actual use.
