From the 07 of the Estonian DDoS information war, to this year Guangxi Nanning 30 internet cafes suffered from DDoS ransomware, and then to the Sina network suffered a DDoS attack can not provide external services for more than 500 minutes. DDoS intensified, attacks increased significantly, the attack traffic is also s

As in the real world, the Internet is full of intrigue. Website DDOS attacks have become the biggest headache for webmasters. In the absence of hardware protection, finding a software alternative is the most direct method. For example, iptables is used, but iptables cannot be automatically blocked and can only be manually shielded. Today we are talking about a software that can automatically block the IP address of

One, why should DDoS? With the increase of Internet network bandwidth and the continuous release of multiple DDoS hacker tools, DDoS attack is becoming more and more easy to implement. Out of commercial competition, retaliation and network blackmail and many other factors, resulting in a lot of IDC hosting rooms, business sites, game servers, chat networks and o
