How to hide unnecessary database interfaces in php

The method for PHP to hide unnecessary database interfaces is: 1. Limit the permissions of database users and only grant the minimum access permissions required; 2. Use environment variables or configuration files to store sensitive information in the code. Instead of writing directly in the code; 3. Use firewall or network isolation technology to protect the database and prevent unauthorized access.

Operating system for this tutorial: Windows 10 system, php8.1.3 version, Dell G3 computer.

To hide unnecessary database interfaces, you can use the following measures:

1. Restrict the permissions of database users and only grant the minimum access permissions they require. Remove unnecessary APIs, functions, and tables from the user's permissions.

2. Use environment variables or configuration files to store sensitive information instead of writing it directly in the code. This avoids exposing sensitive information in code or log files.

3. Use firewall or network isolation technology to protect the database from unauthorized access.

The above measures will allow you to have a more secure program and reduce losses caused by unauthorized access.

The following methods can be considered for implementation:

1. Only create useful database users. Provide only strictly separated user roles to the application, ensuring that each role authenticates only to the appropriate data table or view. These roles can be further divided based on application architecture. You can also manage these usernames using authentication-based authentication.

2. Does not use the default "root" user for any database connections, so you can use a better, more distinguishable username as a unified access point. You can modify settings such as default users, passwords, and ports because changing the default server configuration in-place reduces potential security risks.

3. Encrypted transmission communications: If you wish to secure your connection, you can do so by using SSL. However, at this level of security, certificate management should be a priority.

4. Restrict specific IP addresses: This can be set at the transport layer, which allows authorization per server load balancer, firewall, or other AWS service and application layer means.

In short, please pay attention to security measures when connecting to the database to protect your sensitive data.
