IT technology can be considered as a double-edged sword, which brings us convenience as well as threats. Network security is one of them. Nowadays, with the development of hacking technology, the attacks on servers are not uncommon. How to ensure server security is a problem that is widely concerned in the operation and maintenance industry.
Here are some tips for sever security:
1、Install system patches in time
Whether it is Windows or Linux, any operating system has vulnerabilities, and timely patching to avoid vulnerabilities being exploited deliberately is one of the most important guarantees for server security.
2、Install and set up a firewall
There are many hardware or software-based firewalls, and many security vendors have introduced related products. For server security, installing a firewall is necessary. Firewalls have a good preventive effect on illegal access, but installing a firewall does not mean server security. After installing the firewall, you need to configure the firewall to achieve the best protection according to your network environment.
3、Install network antivirus software
Now the virus on the network is very rampant, which requires installing a network version of anti-virus software on the network server to control the spread of the virus. At the same time, in the use of network anti-virus software, it is necessary to regularly or timely upgrade the anti-virus software, and automatically update the virus every day.
4、Turn off unwanted services and ports
When the server operating system is installed, it will start some unneeded services, which will take up the resources of the system and increase the security risks of the system. Servers that are not used at all for a period of time can be completely shut down; for servers that are to be used during the period, you should also turn off unneeded services, such as Telnet. In addition, you must also turn off the TCP port that is not necessary.
5、Back up the server regularly
To prevent unforeseen system failures or user accidental illegal operations, a secure backup of the system must be performed. In addition to monthly backups of the entire system, weekly changes should be made to the modified data. At the same time, the modified important system files 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 a normal state in time.
6、Set account and password protection
Account and password protection can be said to be the first line of defense for the server system. At present, most of the attacks on the server system on the Internet start with intercepting or guessing passwords. Once the hacker enters the system, the previous defense measures are almost lost, 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 system log program, the system records the situation in which all users use the system, including the most recent login time, the account used, the activities performed, and so on. The log program will generate reports on a regular basis. By analyzing the report, you can know if there is any abnormality.
Server security is a big problem. If you don't want important data to be corrupted by viruses or hackers, I hope this article will help you.
