After purchasing a CVM, you need to pay attention to the following.

Change passwords periodically

Usually, the user also has a default password when the host is leased, regardless of whether the default password is complex or not, the user needs to modify it in time. For the administrator's login password, try to be complex and not repeated to prevent it from being easily detected by attackers. Within a certain period of time, it is best to change the password once every 2-4 weeks to ensure the security of the website.

Use firewalls cautiously

Do not blindly change and enable the firewall, especially on the server, if you modify the default forbidden port because you are not familiar with it, you may not be able to connect. So if you need to modify the firewall settings, it is best to try it on the ordinary machine first, and then set it through the server when there is no problem.

Do not set up the server at will

Most of the server leases are set up according to the size of the enterprise website and the business, and it is best to record the operation steps step by step when changing, otherwise, once there is a setting problem, because you forget the operation process, it is difficult for even professionals to restore the original security settings. Similarly, if you want to change the settings, you can contact more on the virtual machine, familiar with the mode of operation, and second, you need to record the operation process.

Detect Syslog

The system log of the CVM records the usage of the leased server, including the login of the account, the operation of changes and the basic operation of the website. Through the observation and analysis of the report, we can see whether the website, account login and so on are abnormal, so as to do a good job.

Regular data backup

Although this is a very basic thing, it is very important, no enterprise wants the website data to be lost, but no one can guarantee the occurrence of unexpected circumstances, if you do not do a good backup, then the loss is likely to be huge.
