Second, what is DDoS?
DDoS is the abbreviation of the English Distributed denial of service, meaning "distributed denial of service", then what is the denial of service (denial of services)? You can understand that. Any behavior that causes legitimate users to not be able to access normal network ser
legitimate users. The result of this is very obvious, is "unworthy", can be said to be precisely satisfied with the desire of hackers.
Since "unworthy" is not desirable, then what about the effectiveness of routers, firewalls and intrusion detection systems (IDS)? From an application standpoint, filtering unnecessary protocols by configuring routers can prevent simple ping attacks and invalid IP addresses. However, it is often not effective to preve
First, what is a Dos attackDOS is the abbreviation of Denial of service, that is, denial of services, the DOS attack is called Dos attack, the purpose is to make the computer or network can not provide normal service. The most common Dos attacks are computer network bandwidth attacks and connectivity attacks. Bandwidth attack refers to the impact of the network with great traffic, so that all available network resources are exhausted, resulting in leg
attacks consume a lot more resources. The report also disclosed, perhaps more worryingly, the increasing frequency and sophistication of application-level DDoS attacks against data centers, as well as the increasing impact on data center operations.
What impact does this attack have on the data center?
The report disclosed the findings of Internet Data Center (IDC) operators who claimed that application-

DDoS is an abbreviation for the English distributed denial of service, meaning "distributed denial of service", a DDoS in Chinese called a distributed denial of service attack, commonly known as flood attack. First, let's take a look at the relevant definitions.Service: What features does the syst
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
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
The old boy was busy recently because he wanted to train students and correct his homework. He had to write books and videos frequently. He had a bad idea. 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

, and system resources. If all these trends increase suddenly or in a short time, then the monitoring system will issue an alarm.
In a typical enterprise, these events will promote the upgrade of NOC, and the IT team will quickly recruit appropriate people to handle them. The management will also receive a notification saying that the website and applications are not normal, and everyone will think about why the sudden surge in requests.
The first step is to analyze the logs of these requests
