The Internet is also a double -edged sword. While bringing us a convenient life, the Internet attack has also become a problem for webmasters to have a headache. During the server operation, problems such as data loss, websites are hacked, causing user information leaks, etc., and these problems basically cannot be eliminated, only defense can be defended. So what are the common server security protection measures?

　　1. Install the system patch in time

　　Most systems and software have more or less security vulnerabilities. In order to avoid the security problems of the server due to these vulnerabilities, the system patch must be installed in a timely manner during use to repair the security vulnerability.

　　2. Install and set the firewall

　　The server firewall is a security system that protects the information in our computer that is not stolen and invaded by others. It is generally divided into two types: hardware protection and software protection. The firewall itself has a strong defense ability and can resist ordinary small network attacks. Therefore, the installation and setting firewall for the server can greatly improve the network security.

　　In addition, firewalls are also divided into levels. The ordinary version of the firewall can only resist small impacts. Therefore, if the website requires higher defense capabilities, you must choose to strengthen the firewall or high -defense server.

　　3. Installing network anti -virus software

　　Installing network anti -virus software for the server can avoid the adverse effects of virus invasion and improve the security of the system; on the one hand, you can also use anti -virus software to monitor the operating status of the server at all times. Or the harassment of malicious programs improves the stability of the system.

　　4. Close unnecessary services and ports

　　When installing the operating system of the server, some unusable services will be started by default. In order to provide a safer operating environment for the server, the opening of the port should be strictly limited. Generally speaking, the unnecessary port or service should be closed. Essence

　　5. Regular backup of the server

　　In order to prevent the server's data loss, you can regularly make data backup for the server. Although data backup does not seem difficult to operate, it is the most effective way to protect the server. As long as the data backup is regularly made, even if your server is attacked and destroyed, you can quickly reply to the data as long as the system is reinstalled. It is worth reminding that the files of the important system can be placed on different servers so that the system crash (usually the hard disk is wrong), and the system can be restored to normal in time.

　　6. Set account and password protection

　　The first line of defense to protect server security is to set account numbers and passwords for the server. In reality, many attack servers start with interception or speculation password =, so the server account and password protection of the server are extremely important. The protection measures for account numbers and passwords can allocate the authority of accounts and passwords to different personnel management, and regularly update the password.

　　7. Monitoring system log

　　The server monitoring system log can achieve the following functions:

　　Set the login time, the non -landment time login system, and the scheduled command (such as the logoff cancellation system);

　　When the system is logged in, it will send a prompt email to the specified mailbox;

　　Only allow the designated user to log in;

　　The system can record the use of the system's use of the system, including the recent login time, what commands have been operated, and so on.

　　The log program can regularly generate reports for easy viewing abnormal phenomena.
