Server maintenance tip 1: install system patches in time from the basics-no matter Windows or Linux, any operating system has loopholes. Timely patching to prevent vulnerabilities from being deliberately exploited is one of the most important guarantees for server security.

Server maintenance tip 2: install and set up firewalls-there are many firewalls based on hardware or software, and many security vendors have launched related products. For server security, it is necessary to install a firewall. Firewalls play a good role in preventing illegal access, but the installation of firewalls does not mean that the server is secure. After installing the firewall, you need to configure the firewall properly according to your own network environment to achieve the best protection effect.

Server maintenance skill 3: install network antivirus software-now the virus on the network is very rampant, so it is necessary to install the network version of antivirus software on the network server to control the spread of the virus. At the same time, in the use of network antivirus software, the antivirus software must be upgraded regularly or in time, and the virus database must be updated automatically.

Server maintenance tip 4: close unwanted services and ports-when the server operating system is installed, it will start some unneeded services, which will not only occupy the resources of the system, but also increase the security risks of the system. For servers that will not be used at all for a period of time, you can shut down completely; for servers to be used during the period, you should also turn off unwanted services, such as Telnet. In addition, turn off TCP ports that are not necessary.

Server maintenance tip 5: back up the server regularly-in order to prevent unexpected system failures or careless illegal operations of users, a safe backup of the system must be carried out. In addition to the monthly backup of the whole system, the modified data should also be backed up once a week. At the same time, important system files that should be modified are stored on different servers so that in the event of a system crash (usually a hard disk error), the system can be restored to normal in a timely manner.

Server maintenance tip 6: account and password protection-account and password protection can be said to be the first line of defense of the server system. At present, most attacks on the server system start from intercepting or guessing passwords. Once the hacker enters the system, the previous defense measures are almost useless, so managing the account and password of the server system administrator is a very important measure to ensure system security.

Server maintenance tip 7: monitor the system log-by running the system log program, the system will record all users using the system, including the most recent login time, accounts used, activities, and so on. The log program will generate reports on a regular basis, and by analyzing the reports, you can know if there are any anomalies.
