DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for sl
application attack called slow attack (slow HTTP DDOS), on the contrary, is slow connection, consumes all your resources, more famous such as Slowloris.

recently took a little time to "the King of Destruction-ddos attack and the depth of the prevention of the analysis" to read it, frankly, this book is relatively simple, can be said to be an introductory book, of course, for me this kind of DDoS smattering people, is also a good book, at least I learned something.

DDoS deflate is actually a shell script that uses Netstat and iptables tools to block IP that has too many links, effectively preventing common malicious scanners, but it is not really an effective DDoS defense tool.
Work Process Description:
The same IP link to the number of connections to the server after the setting of the cut value, all over the cut value of the IP will be masked, while the shielding

Preface
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

DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing
