分布式拒绝服务攻击的防御策略

Defense Strategies for Distributed Denial of Service Attacks

随着信息技术的快速发展,网络安全威胁也日益增多,其中分布式拒绝服务(DDoS)攻击因其破坏性强和难以防御而成为网络安全的一大挑战。DDoS攻击可以利用大量受控设备对目标服务器发起海量请求,致使其服务不可用。文中详细分析了当前DDoS攻击的主要手段,探讨了基于流量监控、行为分析和机器学习的多种检测技术。在此基础上,还提出了一套包括基础防御措施和高级防御技术的综合防御框架。

With the rapid development of information technology,cyber security is facing an increasing number of threats,among which distributed denial of service(DDoS)attacks have become a major challenge to cyber security because of their destructive power and difficulty in defense.DDoS attacks can use a large number of controlled devices to make massive requests to the target server,making the service unavailable.This paper analyzes the main technical means of current DDoS attacks in detail,and discusses various detection technologies based on traffic monitoring,behavior analysis and machine learning.On this basis,a comprehensive defense framework including basic defense measures and advanced defense technologies is also proposed.
