How to prevent hotel rate audit vulnerabilities in PHP language development?

In recent years, network attacks have emerged one after another, and attacks on websites have occurred even more frequently. The hotel rate audit vulnerability is a very dangerous vulnerability that allows attackers to obtain administrator rights of the website, thereby tampering with website content at will, stealing user information, and causing great losses to enterprises and users. As a common development language for WEB applications, PHP language has many loopholes that need to be paid attention to. This article will discuss how to defend against hotel rate audit vulnerabilities in PHP language development.

What is the hotel rate audit vulnerability?

The hotel rate audit vulnerability means that the attacker injects SQL statements into the input box of the website, thereby obtaining the administrator rights of the website to carry out the attack. By constructing specific query statements, the attacker successfully bypassed the website's login authentication mechanism, obtained sensitive information of the database, and ultimately achieved attack and control of the website.

How to prevent hotel rate audit vulnerabilities?

1. Input verification

Before implementing data transmission, the data submitted by the user should be verified. During verification, pay attention to excluding sensitive characters such as special characters. You can use regular expressions, htmlspecialchars and other functions in PHP to filter the input data.

2. Precompiled statements

When using SQL queries, precompiled statements can be used to prevent injection attacks. Precompiled statements process SQL statements and parameters separately, thereby avoiding the injection of malicious code.

3. Principle of Least Privilege

The principle of least privilege is achieved by reasonably setting the permissions of the database to limit the operating permissions of the database to the minimum range, thereby reducing the risk of being attacked. risk.

4. Random Salt

Adding random salt to sensitive data in the database can make it more difficult to obtain the data directly. By adding random values ​​to the original basis, the difficulty and time cost of the attacker's guess can be increased.

5. Password Encryption

Encrypting the user’s password data is an effective way to improve security. Encryption algorithms such as MD5 and SHA1 can be used for encryption, or higher-level encryption algorithms such as bcrypt can be used.

6. Update software version

Update the software version in a timely manner and enable the latest security policies and plug-ins to ensure the security of WEB applications. Some new versions will fix some security vulnerabilities and improve application security.

Conclusion

Although the hotel rate audit vulnerability is not the latest vulnerability, it is very serious and can be easily exploited by hackers, causing great losses to users and enterprises. In PHP language development, developers must determine how to best protect data security based on their own business needs. Through the above measures, we can effectively defend against hotel rate audit vulnerabilities and ensure the security of WEB applications.
