With the continuous development of Internet technology, more and more websites are beginning to use the PHP language for development, which also makes PHP the target of many hacker attacks. Among them, PHP password is one way of hacker attack, and it is also the most common way. So, how to remove the PHP password and improve the security of the website? Let’s take a closer look.

What is a PHP password?

PHP password is a way for hackers to exploit website vulnerabilities and add a piece of PHP code to the website server. This code will be placed in a file that can be executed, such as an image file, JS file, CSS file, etc. Once these files are accessed, hackers can use this PHP code to obtain sensitive information of the website or perform operations remotely, thus compromising the security of the website.

How to remove PHP password?

1. Timely upgrade the website program

Since the generation of PHP passwords is caused by vulnerabilities in the website program, upgrading the website program is the first step to remove PHP passwords. Because every program upgrade will fix loopholes and improve program security, you must update and upgrade in time when using website programs.

2. Regularly check server files

PHP passwords usually add a piece of PHP code to the file, so searching for files on the server is an important step to remove PHP passwords. You can use some security tools such as PHP Shell Detector to scan folders and files on the server to look for known PHP vulnerability scripts.

3. Delete useless files

Some files are unnecessary, but if they are not cleaned carefully, they will bring great security risks to the website. For example, some old versions of files, backup files or test files should be deleted in time when no longer needed. Because these files are likely to contain a large amount of sensitive information, if they fall into the hands of hackers, they will pose a serious threat to website security.

4. Limit the type and size of file uploads

PHP passwords are often completed through file uploads, so limiting the type and size of file uploads is also a key element in removing PHP passwords. When uploading files, you can first determine the file type and size. Files that do not meet the requirements should be intercepted or deleted.

5. Strengthen authorization and access control

For important files and folders on the server, you can set access control to only allow authorized users to access. When implementing access control, you can use the attributes and permissions of the file, or even the security configuration of the web server itself.

Summary

In today's Internet environment, ensuring the security of the website is crucial. PHP password is a common hacker attack method. Every website administrator needs to pay attention to the security risks in this area. By promptly upgrading website programs, regularly checking server files, deleting useless files, restricting file uploads, and strengthening access control, the security of the website can be effectively improved and the normal operation of the website can be ensured.
