Professional website construction - how should website security be maintained?

Website security cannot be ignored at all. Tens of thousands of websites are invaded every day in the world, and the number is increasing every year. Although the website cannot be 100% secure, we can try our best. There are two parts to ensure website security: server security and website program security. How can we maintain the security of website programs?

As a competent website construction company, a website should at least ensure its security and protect its external from attacks.

1、 Upload security processing.

Generally, websites have a background to update website content. The background HTML editor generally has the upload function. Some websites can also upload files separately. Where the upload function is used, it must be prohibited to upload executable files such as ASP/PHP/JS/NET.

2、 Website background management

The users and passwords of the website background should be as complex as possible. If multiple people manage the background together, each person should use one account, and each account should limit the corresponding functions. If the management personnel resign, change the password in time.

3、 The website should be less open to users to submit data

Because of business needs, the website has the function of leaving messages and comments, so that users can only submit some simple data. Such as text and pictures. Use a simple editor. The submitted text information replaces illegal characters, and the picture information standardizes the picture type.

4、 Close FTP  

If the FTP function is not frequently used on the website, turn off the FTP function and open it again when necessary.

5、 Prohibit entering illegal parameters in the web address

Visitors are not allowed to enter illegal parameters on the website. After receiving the parameters, illegal characters are filtered out. To prevent hackers from injecting through the website.

6、 Install SSL certificate using HTTPS access

1. Authenticate users and servers to ensure that data is sent to the correct client and server;

2. Encrypt data to prevent data from being stolen in the middle;

3. Maintain the integrity of data and ensure that the data will not be changed during transmission.

7、 Website address static processing

Site pages generate static HTML pages or use pseudo static.

8、 Regular data backup

The database shall be backed up regularly, and the website program shall be backed up once before each modification.

9、 Do not use programs of unknown origin

Now there are many free open source programs on the Internet, some of which have been modified, and may have a back door. If you use regular open source programs, you need to update the version in time.

The Internet is the connection of information and people in essence. Cyberspace has become the fifth space after land, sea, sky and outer space. Virtual space and the real world are deeply integrated. To improve the level of network security, each of us needs to start from the little things around us. Everyone is responsible for maintaining network security.
