Start with the basics and configure the system patch in time

Whether it is Windows or Linux, any operating system has loopholes. Timely patching to prevent vulnerabilities from being deliberately used is one of the most important guarantees of server security.

Configure and set up the firewall

Nowadays, there are many firewalls based on hardware or software, and many security manufacturers have launched related products. It is necessary to configure a firewall for server security. The firewall has an excellent preventive effect on illegal access, but the configuration of the firewall does not mean that the server is secure. After configuring the firewall, you need to properly equip the firewall according to your own network environment to achieve the best protection effect.

Configure the network

Nowadays, the virus on the network is very rampant, so it is necessary to configure the network version of the antivirus software on the network server to control the transmission of the virus. Together, in the application of the network antivirus software, it is necessary to upgrade the antivirus software regularly or in time, and update the virus database automatically every day.

Shut down unneeded services and ports

When the server operating system is configured, it will launch some unneeded services, which will occupy the resources of the system, and will also add the security risks of the system. For servers that will not be used for a period of time, they can be shut down completely; for servers to be used during the period, services that are not needed, such as Telnet, should also be turned off. In addition, turn off TCP ports that are not necessary.
