How to deal with DDoS proxy IP attack

In the face of DDoS proxy IP attacks, the following measures can be taken to effectively defend:

Traffic Scrubbing: By monitoring and filtering the traffic entering the network in real time, malicious traffic is identified and isolated, and only legitimate traffic is sent to the target server. This can be achieved through professional DDoS cleaning equipment or cloud services.

Use Content Distribution Network (CDN):CDN distribute users’requests by caching website content to servers in different locations around the world, reduce the pressure on the main server, and has the flexibility to expand.

Load balancing: Use a load balancer to distribute user requests to multiple servers, improve the system's ability to withstand pressure, and dynamically adjust resource allocation according to the change of traffic load.

Firewall and Intrusion Prevention System (IPS): Configure firewall rules to limit the traffic of specific IP addresses, ports and protocols, and use IPS to monitor network traffic in real time, analyze abnormal behavior patterns, and actively prevent potential attacks.

Protocol and connection restriction: by configuring network devices or application servers, limit the traffic of specific protocols, and set restrictions such as the maximum number of connections, connection rate and request frequency.

Strengthen network infrastructure: improve network bandwidth capacity and server resources, strengthen the protocol stack of server operating system and network equipment, and fix known vulnerabilities.

Real-time monitoring and response: configure real-time monitoring tools and establish a response plan, including emergency contacts, communication channels and emergency response processes.

Consider using professional DDoS protection services: Professional DDoS protection service providers have strong infrastructure and professional technical team, which can provide real-time traffic monitoring, cleaning and defense services.

User's browser fingerprint is generated by client information: the user's browser information is collected by JavaScript, and a unique user ID is generated to lock the user's identity. Even if the attacker changes the IP, the user's identity can still be identified by the client information.

Deploy secure accelerated SCDN: Secure Content Delivery Network (SCDN) can filter malicious requests and attack traffic, and is suitable for Web applications. It accelerates content transmission and protects websites through content caching, fast transmission and dynamic routing technologies.

Other defensive measures: including but not limited to using Web application firewall (WAF), optimizing the use of resources to improve the load capacity of servers, enabling the anti-IP spoofing function of routers or firewalls, and using third-party services to protect websites, etc.

Through the above measures, we can build a comprehensive defense system to effectively deal with DDoS proxy IP attacks. At the same time, enterprises should conduct risk assessment and security drills regularly, update and strengthen security measures in time, so as to improve the network's resilience and coping ability.
