Navicat Connecting to MySQL Database: A Security Audit Guide to Ensure无忧 Database Security

# 1. Database Security Auditing Overview

Database security auditing is a process of regularly examining and analyzing database systems to identify and assess security risks, ensuring the security and integrity of the database systems. It involves a comprehensive security assessment of the database system, including user privilege management, database object privilege management, connection security settings, privilege auditing, connection auditing, and database activity auditing, among other aspects.

Database security auditing is crucial for protecting the database systems from unauthorized access, malicious attacks, and data breaches. By conducting regular security audits, security vulnerabilities can be timely identified and addressed, preventing potential security threats and ensuring the secure and stable operation of the database systems.

### 2.1 User Privilege Management

#### 2.1.1 Creating and Managing Users

When creating a MySQL user in Navicat, you need to specify the username, password, host, and privileges.

CREATE USER 'newuser'@'%' IDENTIFIED BY 'password';

* `newuser`: The newly created username
* `%`: Allows users to connect from any host
* `password`: The user's password

To delete a user, you can use the following command:

DROP USER 'newuser'@'%';

#### 2.1.2 Granting and Revoking Privileges

In MySQL, privileges are divided into global privileges and object privileges. Global privileges grant users access to the entire database or server, while object privileges grant access to specific database objects, such as tables, views, stored procedures, etc.

To grant a user global privileges, you can use the following command:

GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'%';

To revoke a user's global privileges, you can use the following command:

REVOKE ALL PRIVILEGES ON *.* FROM 'newuser'@'%';

To grant a user object privileges, you can use the following command:

GRANT SELECT, INSERT, UPDATE, DELETE ON table_name TO 'newuser'@'%';

To revoke a user's object privileges, you can use the following command:

REVOKE SELECT, INSERT, UPDATE, DELETE ON table_name FROM 'newuser'@'%';

### 2.2 Database Object Privilege Management

#### 2.2.1 Table and View Privileges

Table and view privileges control user access to tables and views.

| Privilege | Description |
|---|---|
| SELECT | Allows users to read data from a table or view |
| INSERT | Allows users to insert data into a table or view |
| UPDATE | Allows users to update data in a table or view |
| DELETE | Allows users to delete data from a table or view |

To grant a user table or view privileges, you can use the following command:

GRANT SELECT, INSERT, UPDATE, DELETE ON table_name TO 'newuser'@'%';

To revoke a user's table or view privileges, you can use the following command:

REVOKE SELECT, INSERT, UPDATE, DELETE ON table_name FROM 'newuser'@'%';

#### 2.2.2 Stored Procedure and Function Privileges

Stored procedure and function privileges control user execution permissions for stored procedures and functions.

| Privilege | Description |
|---|---|
| EXECUTE | Allows users to execute stored procedures or functions |

To grant a user stored procedure or function privileges, you can use the following command:

GRANT EXECUTE ON procedure_name TO 'newuser'@'%';

To revoke a user's stored procedure or function privileges, you can use the following
