This article mainly explains "how to defend against attacks on high-defense servers". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn how to defend against attacks on high-defense servers.

How to protect the high defense server?

1. The number of servers should be moderate

In dealing with external attacks, some large companies also need to have satisfied servers to support, because hackers only need to find a loophole to easily attack, when we find a loophole, we may have received a serious attack. What we want to say here is that when hackers attack, they will spend their own capital to meet the number of servers. Perhaps the user's host has not been killed, and the hacker now has no extra energy and capital.

two。 Filter unnecessary services and ports

This refers to filtering out fake IP on the router, opening only the service port is a common practice of high-defense servers nowadays, such as WWW server only opens 80% and closes all other ports or makes a blocking strategy on the firewall.

3. Configure a firewall on the backbone node of the high-defense server

Device firewalls can be useful against DdoS attacks and other attacks. When an attack is found, the attack can be directed to some unimportant dedicated hosts, so that the real host can be protected from attack. Dedicated hosts can also be systems with few vulnerabilities and excellent natural defense attacks, such as linux and unix.

Advantages of High Defense Server:

1. Enhance the overall security of the network

Network security is one aspect of ensuring user experience. Nowadays, many viruses and hackers attack all networks through other computers as an intermediate medium, so webmasters try to choose high-defense servers. Nowadays, most networks are handled by domains, and as long as the virus successfully invades a computer, the security of all networks will be in doubt. We need to think about the security of the network from the root.

two。 Back up data regularly

Magnetic tape is used to retain precious data, but there are also endless security loopholes in data backup, so the backup media should also be maintained usefully when backing up, and the selected high-defense server renter must choose a regular one. after a regular backup, the data can be restored in time after the server is attacked.

3. Strengthen the security level of server local file pattern

The high-defense server is more secure than the general server, and strengthening the security level of the local file pattern of the server can provide users with a more secure environment.
