DDOS protection schemes are so diverse that they will not choose? After reading this article you will be ready

With the increasing frequency of DDOS attacks, which seriously threaten the security of the network environment, the common DDOS protection method of most companies is to pass the security protection requirements to professional service providers, and then consider choosing server products with DDOS attack capabilities .
A complete DDOS attack system consists of four parts: the attacker, the main control end, the agent end and the bai attack target. The main control end and the agent end are respectively used to control and actually launch an attack. The main control end only issues commands and does not participate in the actual attack, and the agent end sends out actual DDOS attack packets.
Each attacking proxy host sends a large number of service request data packets to the target host. These data packets are disguised and cannot be identified from their source. Moreover, the services requested by these data packets often consume a lot of system resources, making the target host unable to do so. Users provide normal services and even cause the system to crash. The main DDOS protection methods are as follows:
1. Connect to the corresponding firewall as needed.
The attacked server is connected to the hardware firewall. It is suitable for a certain scale of network and deploys the security strategy of the entire network; the software firewall is installed on a computer To protect the security of private accounts. There is nothing to say, DDOS protection method enterprises choose hardware firewalls, and individuals choose software firewalls.
2. Hard-resistance by renting ultra-large bandwidth. The
current DDOS attacks are often hundreds of gigabytes, and peak times over T also occur. And the cheapest bandwidth, 10M is about 100, to prevent T-level attacks, the monthly rent is about 100,000. Good is good, it is expensive, suitable for large-scale enterprises with large wealth.
3. Use high-defense CDN
High-defense CDN is an upgraded version of CDN. In addition to the function of quickly distributing information through multiple nodes, it also has powerful defense capabilities. It achieves protection by hiding the source site IP. Many CDN high defenses can choose the size of the protection traffic, and in addition to defending against CC/DDOS attacks, there is also a CDN acceleration function.
Fourth, use distributed cluster defense
DDOS stands for Distributed Denial of Service, even the names are so similar, it is simply born for DDOS protection. It deploys the website system on a large number of servers in a distributed manner to directly disperse the attacker's traffic, and a single cluster defense exceeds 10G. This is the top allocation. The big Internet company has one man, so the price is not affordable for ordinary people.
The DDOS protection method using high-defense CDN has the following advantages: 1. When the website is attacked, there is no need to migrate the database or change the server, saving time, effort and effort; 2. Hide the source server IP of the website, and each node is high-defense server! T-level traffic defense, anti-D and anti-C, and easily respond to attacks such as DDOS and CC; 3. Speed ​​up website access, solve website concurrency, and eradicate problems at the source 4. The most important thing is 7x24h, professional and technical personnel are on standby 24/7. Called anytime.
