The system is being attacked? Use VPS server to prevent

Now the most worrying issue for users is the system attack. Sometimes we are browsing the website and find that the website is being hanged. The impact of hanging horses is very clear, search engine inclusion, user experience, website data security, almost the lifeblood of the website will be hurt. So, is there any better way to solve this problem? The VPS server that comes with the system can help a lot.

Whether it is a stand-alone server or a VPS, you need to protect your server in a normal way. The server is relatively rich in system resources. It is easier to install anti-virus software, firewall, etc. It is also possible to add hard defense to the server, and the method of prevention is relatively more. The VPS is relatively small due to memory or CPU. If the anti-virus software and firewall are installed, the software will be slow and the security defense will be difficult.

If you don't want to use the resource-intensive way to prevent it, then let's analyze the following ways:

One. Anti-virus software is aimed at viruses, and the webmaster uploads most of the VPS. Download the data, your own things are less likely to contain viruses, anti-virus software can choose not to install, because it is very system resources.

Second, the firewall personally thinks it is necessary, Baidu can find that many Trojans come in through the port, which is also an important channel for hackers to invade the computer, and the general firewall has low occupancy of system resources.

III. Operating system patch, if you are using WINDOWS server, the patch must be played, you can choose to open the system automatically update or install 360 security guards to update the patch, the security meaning of the Earth people know .

Four. The read and write permissions of the website directory, the read and write permissions of the directory is a point that many webmasters can easily ignore. Imagine how terrible it is to open the write permission for the visiting users of the website.

Through the above analysis, if the newly purchased VPS is used for security protection as mentioned above, it is believed that the probability of being hanged is much smaller. However, if the webmaster who has been hacked by the horse himself needs to pay attention to the following points:

I. Perform a full-site program check, because after the hacker hangs up, it will upload some code files to hide it, the next time it is convenient to come again. .

II. Check the update time of the files in the website. This can be seen which files have been modified or changed.

III. Delete unnecessary code, files, and specification directory structure. Imagine the difficulty of throwing garbage into the garbage heap.

IV. Try not to use FTP port 21 for port 2, port 3389 for remote login.

After the above detailed description, I believe that everyone has a better understanding of the VPS server, VPS server plays an important role in anti-virus, anti-black, anti-wood, and hope that everyone can make good use of this resource Oh, to protect our system from running safely.
