After understanding the history and classification of design patterns, how should we learn design patterns? Before learning the design pattern, readers must establish a kind of consciousness, that is, the design pattern is not only a method and technology, but also an idea and a methodology. It has nothing to do with the specific language. The main purpose of learning design patterns is to establish object-oriented ideas, program to the interface as much as possible, with low coupling and high cohesion, so that the programs you design can be reused as much as possible. "Specious. Learning design patterns can better understand object-oriented ideas. Design patterns are some design skills and tricks. Don't rise to ideas and methodologies, okay?"
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.
