With the continuous development of the Internet, the Internet has brought us a lot of convenience, Huawei VM The use of the Internet has gradually become popular, but it has also brought some problems such as network attacks, websites being hacked, and network security has also emerged. For example, there are many kinds of network attacks on the Internet, such as pre attack behavior, port penetration, the use of system vulnerabilities, system services, or password cracking, hanging horse websites, etc. In the face of these defenceless attacks, in addition to Huawei VM or other Virtual machine In addition to the security measures already taken by the service provider, how should we do Huawei well Virtual machine To make the security of Huawei virtual machine even better? Next, let's let the Micron Network take you to understand, mainly from two aspects. First, modify or close the server port of Huawei virtual machine
Everyone knows more or less about server ports, and knows that many attacks are implemented using ports. For example, the general remote control port is 3389, which is the default setting. Therefore, there is a risk of being used by intentional people to remotely control and invade local workstations, and steal private information stored on local workstations, However, if the remote control port value is changed to other values, the security of Huawei virtual machine will be greatly improved. Similarly, closing unnecessary ports can greatly improve the security of Huawei virtual machines.
Windows System needs to use the registry editor to modify the port. There are many online tutorials and learning is very convenient; If the Linux system modifies the port, you need to modify the configuration file of the corresponding service.
Second, efficiently use the black-and-white list function of Huawei virtual machine
Both Windows and Linux systems can use internal black and white lists to improve the security of Huawei virtual machines. The white list refers to the operating system, firewall, anti-virus software, mail system, application software, etc. corresponding to the "black list", and almost all those related to control should use the black and white list rule. If the white list is enabled, the blacklisted users (or IP addresses, emails, viruses, etc.) will be unable to pass; On the contrary, if the white list is enabled, users (or IP addresses, emails, viruses, etc.) in the white list will have priority.
The way to set the whitelist for Windows System is to find the firewall from the control panel and add the corresponding port number. For Linux, you can directly enter the command, first edit the summary of firewall rules, and then enter the released whitelist. After this layer is set, your own Huawei virtual machine will be provided with a layer of security.
Both of the above two methods can improve the security of the website. I hope they can help you improve the security of Huawei's virtual machine, and realize that Huawei's virtual machine is an important server equipment of enterprises. You must do a good job in security protection of Huawei's virtual machine at ordinary times. If you don't want to manually adjust it yourself, you can certainly ask the service provider for help, such as Micronet.
Huawei Cloud, a micro network agent, is an excellent cloud computing service provider. It can provide the best service for friends who want to rent Huawei virtual machines to set up private game servers. It has perfect industry solutions and excellent cloud computing technology. The self-developed pure SSD architecture virtual machine breaks the industry record with 50000 IOPS random read/write speed and 800 Mb/s throughput as performance indicators. The ECS elastic virtual machine uses pure SSD architecture hardware devices. It can easily acquire and enable the cloud in just a few minutes to meet your computing needs. Expanding the flexibility of resource use also saves you computing costs, simplifies IT operations, and enables you to pay more attention to core business innovation.
