In addition, it is recommended that users and relevant users improve their network security awareness and security protection capabilities, update and upgrade firmware or service programs in a timely manner, repair vulnerabilities, and standardize security configuration. For servers, computer hosts and smart devices that do not need to provide public Internet services, it is recommended to directly shut down DNS, SSDP, NTP, SNMP, Chargen, Memcached and other services, or block external IP access to these service ports on firewalls or network entrances and exits. For those who need to provide services to designated IP, access control policies such as firewalls can be configured to allow authorized IP access and prohibit other IP access. In addition, some services such as Memcached can also prevent reflection attacks by changing the default service port or changing the transmission protocol type to TCP. For those who need to provide public Internet services, according to the characteristics of reflection attacks, the message traffic of specific reflection attack instructions can be monitored, identified and filtered, and the forged source IP address of reflection attacks can be monitored, identified, limited in speed, limited in flow and intercepted.LINUX: Linux uses the variable tcp_max_syn_backlog to define the maximum half number of connections that the backlog queue can hold. In Redhat 7.3, the value of this variable defaults to 256, which is far from enough. A low-intensity SYN attack can fill up the half-connection queue. We can modify the value of this variable with the following command:为此与理由大吵一架，指责李由包庇李斯，以至于冷战很久。
