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

Big Data DDoS detection--ddos attack is essentially time series data, t+1 time data characteristics and T time strong correlation, so using hmm or CRF to do detection is inevitable! And a sentence of the word segmentation algorithm CRF no difference!

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

DDoS deflate: automatically blocks DDoS attack IP addresses

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

Wireless LAN DDoS attack technology includes those technical points

1. Overview With the development of information technology, various network security problems are emerging. Although WLAN has the advantages of easy to expand, flexible to use and economical, it is particularly vulnerable to the security aspect because of its use of RF working mode. The wireless network based on ieee802.1l has been widely used, but it has also become an attractive target. Due to the serious defects of IEEE802.11 's WEP encryption mechanism and authentication protocol, a series
