This article introduces to you what are the defense measures of high-defense vps, the content is very detailed, interested friends can refer to, hope to be helpful to you.

High-defense VPS is mainly aimed at enterprise users. Relatively speaking, these enterprise users have higher requirements for network security. High-defense VPS provides users with a more secure network operating environment and provides security guarantee for enterprise customers. So, what are the defense measures for high-defense VPS?

What are the defense measures of high defense VPS

In order to find the possible security vulnerabilities, the existing network master nodes need to be scanned regularly and cleaned up in time after the vulnerabilities are found. Hackers generally attack the computers of backbone nodes, because they have high bandwidth, so it is very important to strengthen the security of these hosts themselves. And all the computers connected to the primary node of the network are VPS-level computers, so it is even more important to scan for vulnerabilities regularly.

(1) configure firewalls in the backbone nodes with high defense against VPS

Installing a firewall can effectively resist DdoS attacks and other attacks. When an attack is found, the attack can be directed to some unimportant sacrificed hosts, which can protect the real host from being attacked. Sacrificing hosts can also be systems with few vulnerabilities and excellent natural protection against attacks, such as linux and unix.

(2) use enough machines to withstand hacker attacks

This is an ideal coping strategy. This requires users to have enough VPS, hackers will continue to visit users, during this period, the hacker's own resources are also constantly consumed, the user's host may not have been attacked dead, hackers have no extra energy and resources. This method requires a lot of investment, and most of the equipment is idle in peacetime, which is not consistent with the actual operation of the network of small and medium-sized enterprises.

(3) make full use of network equipment to protect network resources.

Network devices generally include routers, firewalls and other load balancing devices, which can effectively protect the network. When the network is attacked by the outside world, the router is the first to die, but other machines are not dead. The dead router will be restored after a restart, and the startup speed will be faster and will not cause any loss. If other VPS dies, the data will be lost, and it will be a long process to restart VPS. In particular, one company uses load balancing devices so that when one router is attacked and crashes, the other will work immediately. Thus minimizing DdoS attacks.

(4) filter unnecessary services and ports

This refers to filtering out fake IP on the router, only opening the service port is a common practice of high defense VPS nowadays, for example, WWWVPS only opens 80 and closes all other ports or makes a blocking policy on the firewall.

On the high-defense vps defense measures to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
