Dos attacks, DDoS attacks, and DrDoS attacks believe that everyone has already heard of it! DOS is the shorthand for denial of service, which is denial of services, and DDoS is the distributed denial of service is the short of distributed denial-of-service, and DrDoS is distributed Reflection denial Abbreviation for service, which is the meaning of distributed reflective denial of service.
But the most pow
DDoS deflate is a free script for defending against and mitigating DDoS attacks. It uses netstat to monitor and track the IP addresses that create a large number of network connections. When detecting that a node exceeds the preset limitProgramThese IP addresses are prohibited or blocked through the filters or iptables.Official Website: http://deflate.medialayer.com/

CloudFlare the oldest and most common attack against non-DDoS attacks by protecting millions of websites. In traditional DDoS attacks, attackers control a large number of puppet machines and then send a large number of requests to the target server to prevent legitimate users from accessing the site.However, DDoS attacks have been evolving in recent years: attack
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
I. Distributed blocking services (distributed denial of service)
DDoS is a special case of DoS, hackers use multiple machines to attack at the same time to prevent normal users to use the service. After hackers have invaded a large number of hosts beforehand, to install DDoS attack on the victim host to attack the target; some DDoS tools use a multi-level archit

He was invited by a friend to participate in a forum, after a while, I would like to share some of my thoughts on DDOS attacks. If you are interested in in-depth discussions, contact me. Okay, enable the following:1. To defend against DDOS attacks, you m
Interruption of services (denial of service)
Before discussing DDoS we need to know about DOS, DOS refers to hackers trying to prevent normal users to use the services on the network, such as cutting the building's telephone lines caused users can not talk. and to the network, because of bandwidth, network equipment and server host processing capacity has its limitations, so when the hacker generated excessive network packet so that the device can not

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
In the network security world, DDoS attacks are not a new term. The earliest DDoS attacks date back to 1996, and in China, DDoS attacks began to occur frequently in 2002, and 2003 has begun to take shape. In recent years, however, this cliché of cyber-attacks has created a huge cyber-security threat with new ways of attacking.

Introduction to DDoS Deflate
DDoS deflate is a free script for defending and mitigating DDoS attacks. It creates an IP address for a large number of network connections through Netstat monitoring trails that prohibit or block these IPs through APF or iptables when a node is detected that exceeds the preset limit.
DDoS
Defense principleThe principle of DDoS deflate is to use the netstat command to find a single IP that emits an excessive amount of connectivity and to reject the IP using the iptables firewall. Because the iptables firewall is far more efficient than the Apache-level connection, the iptables becomes the "filter" that runs on the Apache front end. Similarly, DDoS deflate can also be set up to use APF (advanc
I believe you have heard of DoS attacks, DDoS attacks, and DRDoS attacks! DoS is short for Denial of Service and DDoS is short for Distributed Denial of Service and Distributed Denial of Service. DRDoS is short for Distributed Reflection Denial of Service, this is the meaning of Distributed Denial-of-Service.
However, the most severe attack method in these three cases is
