Portal Web DDoS Simulated Attacks and Safety Protection

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.
