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.

Successful investors usually have a good strategic vision, and they are more willing to think about issues that will play a decisive role in the long-term future. On the other hand, ordinary people are just the opposite. A sharp rise one day can immediately make them excited and ignore the failure of the overall result. When a person considers a 10-year cycle, he will have a future. If he is only used to thinking about tomorrow's problems, he is doomed to reap the continuation of yesterday. The money earned in the stock market depends either on intelligence or perseverance. To make a lot of money, one must give consideration to intelligence and perseverance. The money lost in the stock market is either due to cleverness or small temper, which can successfully lose the most money by combining cleverness and small temper.
