门户网站DDoS模拟攻击及安全防护

Portal Web DDoS Simulated Attacks and Safety Protection

针对云南省地震局互联网门户网站系统进行分布式拒绝服务(DDoS)模拟攻击,通过单台短时间内发送大量SYN Flood包分别检测网络与服务运行情况,从交换机端口镜像获取数据包分析攻击特性,从而检测网络流量数据安全防护能力;结合安全软件、硬件资源针对门户网站系统安全提出防护措施建议,对网络中存在的信息安全漏洞进行修复,提高网络信息安全。

The distributed denial of service(DDoS)simulation attack is carried out on the web portal system of Yunnan earthquake agency.Through sending a large number of SYN Flood packets in a short period of time,the network and service operation conditions are respectively detected,and the packet analysis attack characteristics are obtained from the port image of the switch,so as to test the security protection capability of network traffic data.Combined with security software and hardware resources,this paper proposes protective measures for portal system security,and fixes the information security holes existing in the network,so as to improve the network information security.
