What is a DDoS attack and what are the dangers of a DDoS attack?

What is a DDoS attack?

DDoS is an acronym for Distributed Denial of Service, which translates to "Distributed Denial of Service", a DDoS attack combines multiple computers located in different locations into a single attack platform that launches a DDoS attack on one or more targets,anti DDOS thereby multiplying the power of the attack. It is called a distributed denial-of-service attack because the attack points are located in different places.

How the attack works

DDoS attacks a large number of useless requests take up network resources, leading to congestion control, server downtime and other purposes.DDoS attacks come in various forms and can be broadly categorized as follows.

Interfering with or even blocking normal network communications through network overload;

Overloading the server by submitting virtual Machine cloud a large number of data requests to the server;

Preventing users from accessing the server.

Blocking communication between a service and a specific system or individual.

Phenomenon of Attacks

DDoS attacks are one of the most common and destructive types of network attacks. When DDoS attacks occur, they tend to exhibit the following characteristics.

1. Bandwidth is heavily utilized

Taking up bandwidth resources is the main means of DDoS attacks.vpshosting If you find that the network bandwidth is occupied by a large amount of useless data and it is difficult to process normal requests, then the website may be subject to a DDoS attack.

2. Server CPU is heavily occupied

DDoS attacks use chicken software or attack software to send a large number of invalid requests to the target server, resulting in a large number of server resources are occupied, so if the server has a period of time of CPU overuse, then the website may be affected by DDoS attacks.

3. Domain ping is not available

When the attacker's target is the DNS domain name server of the website, the IP of the ping server is connected normally, but the website can not be opened normally, and the ping can not be carried out normally when pinging the domain name.

4. Server not connected

If the web server is subjected to a large number of DDoS attacks, it may cause the server to blue screen or crash, which means that the server can no longer be connected, and the website connection error. Fourth, the harm of the attack

Danger of DDoS Attacks

DDoS attack can cause serious network congestion and server paralysis, which brings great negative impact to the government and enterprises.

1. Damage to business

If the server is inaccessible due to a DDoS attack, it will lead to a serious loss of traffic, which in turn will have a serious impact on the entire network platform and the business of the enterprise. Websites such as gaming platforms, online education, e-commerce platforms, financial industry, live broadcasting platforms and other business-driven websites are most affected by DDoS attacks.

2. Image damage

Lack of access to the server will lead to a decline in user experience, increased user complaints and other issues, not only will affect the conversion rate of potential customers and transaction rates, existing users will also re-evaluate the security and stability of the enterprise, the company's brand image and market reputation will be seriously affected.

3. Data Leakage

Nowadays, DDoS is increasingly used as a cover for other cybercrimes. When the website is almost paralyzed, the whole effort of the maintainer is on anti-DDoS, and it is easier for the attacker to steal data, infect viruses, malicious spoofing and other criminal activities.
