We all know that the so-called high defense server mainly refers to an independent single hard defense server of more than 50G, providing security maintenance for a single customer, helping website denial of service attacks, and regularly scanning existing network master nodes. the type of server that finds possible security vulnerabilities can be defined as a high-defense server. At present, the high-defense server has been applied to various fields, and its status is evident. Then you may not know the defense principle of the high-defense server. Today, the editor will sort out the knowledge about the principle of the high-defense server and how to resist external attacks.

1. Network security defense

If you want to explore what the defense mode of the high defense server is, at present, among the high defense servers on the Internet, there is another kind of server that strengthens the network defense. This kind of server is the same as the ordinary server in hardware, but has a special IP hidden design on the data, which makes it impossible for outside attacks to directly find this server to attack. This is also a very effective form of defense.

2. Network physical defense

Generally speaking, the high-defense server we come into contact with refers to the physical defense, that is, a layer of firewall is added to the hardware that shuts down the server directly, which is like strengthening a layer of "armor" on the outside to protect it from attack. Through the upgrade of hardware to resist physical attacks, which is known as the high-defense server.

How to defend the high defense server?

As the name implies, the high-defense server is to defend against network malicious attacks, so how does the idc service provider defend against network malicious attacks? How does the high-defense server defend compared with the ordinary server?

1. High-defense servers are scanned regularly to remove security risks: most malicious network attacks attack backbone nodes, so Idc service scans backbone nodes regularly to find possible security risks and clean them up in a timely manner, so as not to give attackers a chance.

2. The high defense server will configure the firewall in the backbone node: the firewall can filter the network malicious attack, greatly improve the network security and reduce the risk caused by the network malicious attack. At present, Tengzheng Technology, which has reached strategic cooperation with Golden Shield, has adopted a 3D three-dimensional defense system on the backbone nodes, which can ignore CC attacks, defend against 480g DDOS attacks, and basically ignore arbitrary network attacks.

3. Sufficient bandwidth redundancy in the computer room where the high-defense server is located: bandwidth consumption attack is one of the main forms of network malicious attacks, and a large number of attack packets will lead to server bandwidth congestion, which requires sufficient bandwidth redundancy in the computer room where the high-defense server is located.

4. The high-defense server can filter out unnecessary IP and ports: filter out fake IP on the router, and only open the service port on the high-defense server to close the rest of the port. For example, the XX server only opens port 80 and closes other ports or makes a blocking policy on the firewall.

For idc users such as games, videos and corporate websites with high network security, the high-defense server can give users a more secure and stable network operating environment, which is conducive to the smooth and steady progress of the business.
