For Internet cafe owners, the virus is a big headache. If you have experience in Internet cafe or data center management, you must know that viruses on machines are a headache, in particular, Intranet server DDoS attacks and switch DDoS attacks directly affect the security of Internet cafes.

as the most commonly used hacker attacks on the Internet, DDoS attacks appear, the damage must be small, especially in recent years,the cost ofDDoS attacks is increasingly cheap, hackers simply intensified attacks, for The game industry, where DDoS attacks are hardest hit, is miserable. So why is the gaming industry vulnerable to DDoS attacks? There are four ma
Introduction to DDoS
The most common attack is a distributed denial of service (DDoS) attack on a Web site. In a typical DDoS attack, an attacker consumes service resources by sending a large amount of data to the server. To prevent access to other users.
If a hacker uses JavaScript DDoS attacks, then any computer ca
In the event of a server encounter, DDoS (Distributeddenialofservice, distributed denial of service) attack is a very good hacker behavior, it can make a large server cluster can also be a quick access failure. 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 im
1 DDoS: Distributed Denial of Service
DDoS attacks, that is, distributed denial-of-service attacks, are common attacks that are difficult to prevent. Hackers generally attack domain names by creating botnets, that is, embedding specific malicious programs in computers to control a large number of bots (machines that can be remotely controlled by hackers ), then, attackers send attack commands to a relative
In the third quarter of 2015, 46% of DDoS attacks came from Linux computers.
According to research reports from Kaspersky Labs and Imperva in the third quarter of this year, DDoS attacks have become a very frequent topic and even mask many more serious attacks, it becomes an important means of extortion and interference to enterprises or competitors.
The Kaspersky Lab's third quarter of 2015
15 methods against DDoS attacks, ddos15This article mainly introduces 15 methods against DDoS attacks. There are two main types of DDoS attacks: bandwidth depletion attacks and resource depletion attacks. In order to effectively curb these two types of attacks, you can follow the steps listed in this article. For more information, see

Background: There are many types of DDoS attacks, including traffic attacks that consume network bandwidth and application layer attacks that consume server resources. Which has a huge impact and makes large companies and small companies "awe-inspiring" Traffic attacks. Today, when traffic is getting cheaper, the attack traffic is several hundred megabytes, while the attack traffic is several GB, or even more. The hardest hit by
DDOS (Distributed denial of service) conceptsDDoS is called distributed denial of service, and DDoS is the use of reasonable requests to forge resources overload, resulting in service unavailability. For example, a parking lot has 100 parking spaces, and when 100 parking spaces are full, there is a car that wants to come in. You have to wait for an existing car to come out first. If the existing car does no
In the article prolexic released the first quarter of 2014 Global DDoS attack report published by quickshield, we learned that the attack traffic initiated by the "Reflection amplification" technology increased by 39% compared with the previous quarter, at the same time, attackers are constantly exploring other basic Internet services to launch DDoS attacks. For example, in March this year, the security com
DOS means that attackers send a large number of service requests to the network within a certain period of time, consuming system resources or network bandwidth, occupying and surpassing the processing capabilities of the attacked host, resulting in excessive network or system load, stop providing normal network services to legal users. DDoS introduces the Client/Server mechanism on the basis of DOS, which makes the attack more powerful and more conce

The heart of the people must not be. There are always some boring or intentional people on the Internet. I don't have much to say. On dry Goods, configure VPS APF to prevent small traffic DDoS attacks.
For large traffic DDoS attacks, the need for the computer room hardware firewall, the internal VPS may also be unable to carry.
