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
is 65536 bytes. Although the length of a package cannot exceed 65536 bytes, the overlapping of multiple segments of a package can be achieved. When a host receives a packet larger than 65536 bytes, it is under the Ping of Death attack, which will cause host downtime.
Teardrop: When an IP packet is transmitted over the network, the packet can be divided into smaller segments. Attackers can perform TearDrop attacks by sending two (or more) packets. The

traffic cleaning devices in close proximity to the attack source. Each cleaning device only cleans a portion of the devices, it has a huge amount of abnormal traffic cleaning capability, and its protection capability is very flexible, not only to meet the current needs, but also to meet the needs of higher large-volume DDoS attacks.Abnormal traffic cleaning requires the combination of detection and cleaning capabilities. If only near-source traffic c
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
The basis for successfully mitigating DDoS attacks includes: knowing what to monitor, monitoring these signs around the clock, identifying and mitigating DDoS attacks with technology and capabilities, and allowing legal communication to reach the destination, real-time skills and experience in solving problems. The best practices discussed below reflect these principles.
Best Practice 1: centralize data co
Ddos-deflate is a very small tool for defense and mitigation of DDoS attacks, which can be tracked by monitoring netstat to create IP address information for a large number of Internet connections, by blocking or blocking these very IP addresses via APF or iptables.We can use the Netstat command to view the status of the current system connection and whether it is compromised by a

Considerations and testing methods for DDOS Security Products in the Internet cloud ecosystem (I)The three elements of DDOS attack security are "confidentiality", "integrity", and "availability". DOS (Denial of Service) targets "availability" of services ". This attack method exploits the network service functional defects of the target system or directly consumes system resources (mainly network resources)

DDoS attack wave affects Enterprise Development
DDoS attacks cannot be ignored by enterprises nowadays. In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con
The internet is rich and colorful, basically able to find the resources we need, but also because so many friends are joined to the ranks of the webmaster. Among the many stationmaster also can exist infighting thing. In particular, our personal webmaster, due to limited technical and financial resources, very easy to use on the host, VPS after the attack did not have the ability to defend, leading to our host or VPS to our account suspension, IP hangs and so on. In particular, we are using the

The code is as follows
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 firewall equipment will be paralyzed due to limited processing capacity, become a network

DDoS is a shorthand for distributed denial-of-ser
