What is DDoS? DDoS attacks are a test proposed by an attacker to deplete resources available to the network, the application or the service, so that real users cannot access those resources. It is an attack by a group of malicious software-infected computers or voluntary client computers that attempt to deplete the resources of a particular network, web site, or service. However, not all

This blog can be said that even the prologue can be omitted, the reason is DDoS, not because of the mad dog was chasing bite, but because of the VC after the tragedy of the flow to SIMPLECD. Not only that, some fools are grasping the station, some fools are downloading with the Thunder, the 100Mbps port actually has already been operating at full load for more than 10 hours, what is this concept? 100Mbps full load 1 days, the flow is 1000G, so not lon

Mod_evasive is a DDoS-resistant module for Apache (httpd) servers. For Web servers, it is now a good extension to protect against DDoS attacks. Although it is not completely defensive against DDoS attacks, under certain conditions, it is still the pressure to slow down the Apache (httpd) server. If you work with iptables, hardware firewalls, and other firewall de

Then, how can we determine whether the website is under DDOS attacks? In summary, when the website is under DDOS attacks, the following symptoms may occur: If the website server has all of the following symptoms, the website is basically determined to be under DDOS attacks. 1. The normal services provided by the website become abnormal. This symptom is: The Webpa

When it comes to the ultimate weapon of hackers, it really has to be about DDoS. Can some users of this thing is not very know, but the people engaged in computer security is often heard this name, its degree than the fear of the grave. After all, this DDoS has some place to be so fearful, below will make some brief elucidation to you. In general, the DOS approach is your network's TCP/IP interior layout,

Suitable for readers: DDOS researchers, webmasters, and network administratorsPrerequisites: Basic ASP Reading Capability Many of my friends know the bucket theory. The maximum capacity of a bucket is determined not by its highest capacity, but by its lowest capacity. The same is true for servers, the security of a server is also determined by its most vulnerable aspect. The most vulnerable aspect is how dangerous a server is. The same is true for

To prevent DDOS attacks, you do not have to use a firewall.I have specially sorted out the anti-DDOS attack information to address the shameless behavior of the legendary private server webmasters!It can definitely prevent attacks against the legendary port or the high-traffic DDOS attack on the WEB against approximately 0.4 million packets.Set protection for 80.

Detailed description of Linux iptables firewall + anti-DDOS policy configuration The network firewall function has been implemented in the Linux kernel for a long time. In different Linux kernel versions, different software is used to implement the firewall function.In the 2.0 kernel, the firewall tool is ipfwadm.In the 2.2 kernel, the firewall tool is ipchains.For kernels later than 2.4, the firewall operation tool is iptables. Ipfwadm and ipchains a

increasing the memory and modifying the number of maximum file descriptors (FD). So the question is, how is the DDoS attack going? Number of TCP semi-connections for DDoS attacks 　　In a DDoS attack, if the server allows a large number of TCP connections, server memory is very large, then the attacker is often to send a large number of TCP semi-con
