As DDoS attacks against websites are becoming more and more serious now, DDoS attacks work by using server vulnerabilities in a simplified way. In order to solve this problem, the best way is to use a professional Hong Kong high defense server, then Hong Kong How does the high-defense server resist attacks? Here is a brief introduction.

In addition to the hardware firewall, Hong Kong Anti-DDoS Server has the following measures to protect against DDos:

1. ACL table control

If only a few computers are the source of the attack, the Hong Kong high-defense server can identify the IP address that initiated the attack. Generally, the high-defense computer room will place an access control list (ACL) on the server firewall to prevent access from these IPs. If possible, change the server IP address for a while, but if an attacker can resolve the newly configured IP by querying a DNS server, the address is no longer valid.

2. Elastic protection

Using elastic protection security solutions, it can provide protection for Layer 7 DNS DDOS or TCP/IP attacks. Resilient DDoS Protection (delivered as a service on the network edge) Protection strength depends on threat complexity and scale, and can mitigate DDoS attacks of all shapes and sizes, including DDoS attacks against UDP and ICMP protocols such as SYN/ACK, DNS Amplification and layer 7 attacks.

3. Flow monitoring

to monitor incoming traffic from the network. This way, you know who is accessing your network and can monitor your visitors for anomalies. Usually, before a large-scale attack, the attacker can use a small number of attacks to test the health of the network. For example, the high-defense computer room in Hong Kong adopts 24-hour real-time monitoring to ensure the stability and security of the server.

4. Efficient network cleaning

To ensure the network security of the server is inseparable from an efficient cleaning mechanism, generally many high-defense computer rooms have a dedicated cleaning center, and through customized routing rules to achieve load balancing and divert malicious traffic into a dedicated cleaning center to ensure that the machine network security
