This article shows you how to do a good job of server security protection, the content is concise and easy to understand, can definitely brighten your eyes, through the detailed introduction of this article, I hope you can get something.

IT technology can be said to be a double-edged sword, which not only brings us convenience, but also brings threats, and network security is one of them. Nowadays, with the development of hacker technology, it is not uncommon for servers to be attacked. How to ensure the security of servers is a widespread concern in the field of operation and maintenance.

We have no way to completely solve the problem of network security, but we can constantly strengthen the protection and improve the defense ability of the server. So how can we improve the security of the server? IT operation and maintenance experts provide seven tips for maintaining server security.

1. Start with the basics and install the system patch in time

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 of server security.

two。 Install and set up the firewall

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.

3. Install network antivirus software

At present, 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 the network antivirus software, the antivirus software must be upgraded regularly or in time, and the virus database is updated automatically every day.

4. Shut down unwanted services and ports

When the server operating system is installed, it will start some unwanted services, which will occupy the resources of the system and 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.

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 have been modified should be 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.

6. Set 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.

7. Monitoring system log

By running the Syslog program, the system records all users' use of the system, including the most recent login time, accounts used, activities carried out, 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.

Previously, I signed up a CVM in the Bird Cloud activity. By the way, I recommend a free and useful server operation and maintenance panel-Cloud Helper (click on the official website to download)

Cloud helper-multiple active defenses are more secure

One-click repair of safety inspection

24-hour uninterrupted system comprehensive physical examination, system vulnerability scanning, system one-click reinforcement, so that the risk will have nowhere to hide!

System security protection

Improve the security factor of the server by automatically opening the system firewall, disabling PING on the server, modifying the default port of RDP, etc.

Manage the system listening port and manually select the trust port to prevent the system from being affected by broilers.

Control outbound and inbound IP to easily deal with all kinds of IP-based attacks

Network security protection

Through the network connection control, you can see the protocol type, local address, occupation process, etc., and can be added to the port whitelist and IP blacklist to improve network security.

Security log audit

Use big data technology to store the host and Web event logs, guide customers to query and analyze the logs from a security point of view, find clues of hacker intrusion, and restore the attack scene.
