Creating and Managing User Accounts:

Creating User Accounts:

one can generate accounts for users by the means of 'CREATE USER' statement where the user name and host from which the particular user can connect are specified.

                        
                        CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
                        
                    

Deleting User Accounts:

Use the DROP USER statement to delete user accounts.

                        
                        DROP USER 'username'@'localhost';
                        
                    

Modifying User Accounts:

Use the ALTER USER statement to modify user account properties such as password or privileges.

                        
                        ALTER USER 'username'@'localhost' IDENTIFIED BY 'new_password';
                        
                    

Setting Privileges and Permissions:

Granting Privileges:

Privilege users for the SELECT, INSERT, UPDATE, and DELETE statements at the database, or table levels by using the GRANT statement.

                        
                        GRANT SELECT, INSERT ON database_name.* TO 'username'@'localhost';
                        
                    

Revoking Privileges:

Use the REVOKE statement to revoke previously granted privileges from users.

                        
                        REVOKE INSERT ON database_name.* FROM 'username'@'localhost';
                        
                    

Viewing Privileges:

You can view the privileges assigned to users using the SHOW GRANTS statement.

                        
                        SHOW GRANTS FOR 'username'@'localhost';
                        
                    

Securing MySQL Server:

• Use Strong Passwords:

  Enforce strong password policies for user accounts to prevent unauthorized access.

• Limit Network Access:

  From the firewall, configure access rules preventing the server MySQL port (port 3306) to outside of trust IP or networks only.

• Enable SSL/TLS Encryption:

  MySQL server configuration must be established to employ SSL/TLS for the secure communication between clients and the server.

• Regularly Update and Patch:

  Make sure to keep the server secure by keeping it updated with the most recent security patches and revisions to rectify well-known vulnerabilities.

• Monitor and Audit Access:

  Ensure logging and monitoring capabilities are implemented in MySQL, so that the user activity are traced and those attempts that are unlikely or even unauthorized are identified.

• Implement Role-Based Access Control (RBAC):

  By creating user roles and issuing affiliated privileges, you can group permissions according to the user’s role throughout the organization.
