How to set the CVM to disable the firewall? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

It is relatively simple to disable firewall settings for a CVM. Take Windows as an example. After logging in to the CVM console, click "start"-> "Control Panel"-> "Firewall Settings" to enter the firewall settings page.

Check whether the firewall and other security software (such as security dogs, etc.) are turned on, and if so, turn it off. Firewall is a technical measure to protect computer network security, which plays an important role in preventing network intrusion from outside. If the CVM firewall is turned off, it will not have the following functions.

1. Network security barrier

A firewall (as a blocking point, control point) can greatly improve the security of an internal network and reduce risk by filtering insecure services. Because only carefully selected application protocols can pass through the firewall, the network environment becomes more secure.

For example, firewalls can prohibit insecure NFS protocols from entering and leaving the protected network, so that it is impossible for external attackers to use these fragile protocols to attack the internal network. Firewalls also protect cyberspace from routing-based attacks, such as source routing attacks in IP options and redirect paths in ICMP redirects.

two。 Network security strategy

Through the firewall-centric security scheme configuration, all cloud security software (such as password, encryption, authentication, audit, etc.) can be configured on the firewall. Compared with distributing the network security problems to each host, the centralized security management of the firewall is more economical. For example, when accessing the network, the one-time password system and other identity authentication systems can be concentrated on the firewall instead of being scattered on each cloud host.

This is the answer to the question about how to set up and close the firewall on the CVM. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
