The main method of mitigating DDOS attacks is to clean network traffic, that is, try to remove malicious network traffic from all traffic, and only deliver normal network traffic to the server. However, with the increasing traffic of distributed denial of service attacks , a single traffic cleaning device and traffic cleaning center can no longer handle such a large-scale network traffic. A typical mitigation process can be broadly defined as the following four steps:
Detection – Identify those DDoS Attack traffic deviations that may accumulate . Effectiveness depends on your ability to identify attacks early, with the ultimate goal of real-time detection.
Steering – Steering traffic away from the target, either being filtered out or discarded entirely.
Filtering – Weeds out DDoS traffic, often by instantly identifying legitimate traffic (ie people, API calls, and search engine bots) and malicious visitors. Responsiveness is your ability to block attacks without affecting the user experience. The goal is to make your solution completely transparent to site visitors.
Analysis – Examine security logs to gather information about attacks, identify attackers and improve future resilience. The effectiveness of this process depends on being able to provide detailed security logs with nuanced visibility into attack traffic.
You should also choose a supplier with mitigation solutions. Different suppliers will provide different solutions. Imperva Incapsula is recommended. The technology is your guarantee and the service meets your needs.
