What is the best way to defend against DDoS and CC attacks

DDoS attack defense methods.

1. Filter unnecessary services and ports: You can use tools such as InExpress, Express, and Forwarding to filter unnecessary services and ports, that is, filter fake IPs on the router.

2. Cleaning and filtering of abnormal traffic: Through the cleaning and filtering of abnormal traffic by the DDOS hardware firewall, through the rule filtering of data packets, the detection and filtering of data flow fingerprints, and the customized filtering of data packet content, it can accurately judge whether the external access traffic is normal, and further prohibit the filtering of abnormal traffic.

3. Distributed cluster defense: This is currently the most effective method for the network security community to defend against large-scale DDoS attacks. The feature of distributed cluster defense is that each node server is configured with multiple IP addresses, and each node can withstand no less than 10G DDoS attacks.

4. Anti-DDoS intelligent DNS resolution: The perfect combination of the high-intelligence DNS resolution system and the DDoS defense system provides enterprises with super detection functions to combat emerging security threats. It subverts the traditional practice of one domain name corresponding to one image, and can only resolve DNS resolution requests to the server of the user's network according to the user's Internet route.

At the same time, the intelligent DNS resolution system also has a downtime detection function, which can intelligently replace the paralyzed server IP with a normal server IP at any time, so as to maintain a service state that will never go down for the enterprise network.

CC attack defense method.

1. Choose a reliable anti-DDoS server to improve server hardware and network bandwidth resources: High-performance server hardware capabilities and sufficient network bandwidth resources can improve the system's carrying capacity against CC attacks.

3. IP shielding restrictions: identify the source IP of the attacker, and for the source IP of CC attacks, you can set to block the IP in IIS and restrict its access, so as to prevent IIS attacks.

4. Deploy Anti-DDoS Pro: Access the Anti-DDoS Pro CDN, conceal the source IP of the server, automatically identify the attack traffic, and return the normal visitor traffic to the source server IP after cleaning to ensure business security.

5. Close unnecessary ports and services.

Point me. Nickname My Profile can help you out.

Anti-DDoS Pro server plus CDN is pretty much the same.

It is a good choice to use high anti-DDoS, and you can use a defensive shield with large traffic cleaning, hidden IP, and distributed defense for large traffic.

The principle of DDoS attack is that I generate a DDoS client to spread on the network, and when someone opens it, of course, there is not only one computer, I can use my client to use a command to make all the computers that I implant in the control end send an access request to a **, for example, I have millions of computers controlled by me If each computer sends an access request **If it is processed.
