Guide: MySQL Security

MySQL Access Control

Access controls are an essential part of the data security infrastructure and regulate who is permitted to access which data and for how long. Access controls rules check the individual credentials against the applicable correct extent of access to the data by utilizing verification and authorization procedures.

The MySQL software produces a SQL or Structured Query Language database server that is blazingly fast, supports multiple threads and users, and is very reliable. 

This article aims to lay out the groundwork to help you better understand the MySQL access control system so you can begin protecting your organization’s data by covering the following topics:

What is a MySQL Server?

MySQL servers provide a platform for storing and managing databases, allowing multiple clients or application to connect simultaneously so they are designed to embed into manufacturing systems that handle severe loads and mission-critical data. They are also regularly used in organizations that handle large numbers of users. 


MySQL servers can be configured and customized to meet specific requirements, such as setting up security measures, defining user access privileges, optimizing performance, and enabling various features and extensions offered by MySQL.

MySQL Account

MySQL permits the establishment of profiles, allowing the users to link to the domain controller and view data that the server controls. Moreover, you can use these accounts to retrieve data from the server. The fundamental purpose of the MySQL privilege framework is to verify an individual who enters the connection from a certain host and to link that user with permissions on a system. These privileges include selecting, adding, updating, and clearing information from the database. One of the additional features is the capability to grant privileges to perform administrative functions.


Authentication credentials, including a password, can be issued to every account so that the administrator can exercise control over which individuals can log in. SQL instructions like new user, grant, and revoke make up MySQL’s user interface for logging in and managing accounts.

MySQL Privilege System

The privilege system connected to MySQL guarantees that users can only carry out the tasks relevant to their roles. When an individual is connected to a MySQL server in a user’s role, the identity is established based on the host you click and the user ID you supply. Once the user has successfully connected, they can send requests. At that point, the system will grant or drop privileges based on the identification and the tasks they wish to perform.


There are several distinct levels of functions and situations in which you can apply MySQL privileges, each of which results in a different set of capabilities.


  • Users with administrative access are granted the ability to manage how the MySQL server operates. These permissions are global since they are not limited to a single database in any way.
  • Database privileges apply not only to the database itself but to any data stored within it. Users can grant and revoke privileges only for certain databases, the system as a whole, or worldwide so that they apply to all database systems.
  • Privileges for data items such as rows from a table, indexes, viewpoints, and saved procedures can be permitted for specific objects contained within a database across all objects of a specified category contained within a database. This option includes all tables or a table in a database. You can also give privileges to particular things contained within a database.

Show Grants Statement

The show grants statement presents the rights and roles given to a MySQL user account or function in grant statements. These grant statements need to be implemented to duplicate the permissions and role delegations displayed by this statement. Show grants statement does not disclose privileges accessible to the given account but awarded to a separate account.

Grant Tables

The MySQL system database that serves as MySQL’s backbone contains several and reloads the grant tables. These tables are where data about user profiles and the permissions they have access to is stored.


Grant tables explain the basic layout and how the servers use the information inside those tables when communicating with their clients. However, one cannot manually alter the grant tables in most cases. Indirect adjustments occur when users set up profiles and regulate the privileges accessible to each user by using account-management statements, including creating users, granting, and revoking. These statements make it possible to make modifications.

MySQL Access Control Best Practices

It is a best practice for security management to be cautious and to expect an attack at any moment from any source. But, if one takes some preventative precautions, it will be easier.

Remove MySQL's History

MySQL installs a default history record. This file contains the setup and setting history. If exploited, it could disclose database credentials.

Plugin Authentication

Authentication plugins let users choose a method. One can integrate MySQL’s pluggable authentication options for enhanced security.

Encrypt Stored and Transmitted Data

MySQL’s unsecured server-client connection allows attackers to steal data. Unencrypted user data can threaten the user’s privacy and security. However, intranet interactions may not need encryption. MySQL encrypts data at rest to protect it from a server attack.


Access control is a crucial aspect of data security and Satori’s Data Security Platform provides a comprehensive automated solution. Satori’s managing and monitoring of access to sensitive data enable organizational leaders to be assured of privacy and security. Satori easily integrates with MySQL for highly capable access control functionality to help organizations better protect the data they store.
