At present, under the guidance of the Network Security Administration Bureau of the Ministry of Industry and Information Technology, CNCERT organizes provincial sub-centers, operators, security enterprises, cloud service providers, etc. to continuously carry out DDoS attack resource management, requiring all units to timely notify and process servers, computer hosts and intelligent devices found to be used for reflection attacks, and requiring operators to strengthen the fine management of false source address traffic. 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.Reference to my equipment: weightlifting belt, 80 yuan, double-row cowhide 7mm, original price about 300 yuan, because it is XL code of US, special price.
