Security Issues in MySQL

Web hosting companies maintaining a MySQL database certainly understand the importance of tight security. Content stored in your database needs to be secure at all time, and kept away from the eyes of hackers. Security problems in MySQL can flaw a web server in numerous ways; here are the two major categories in which they are grouped: File System risks and Network risks.

File System Risks

Information on a MySQL database is stored in several files and directories. This system also keeps tracks of log files that detail information concerning queries that users command. Since these files and directories are components of the file system, they must be secured in order to prevent other users on web hosting servers from gaining access to the account.

Installation of a MySQL database contains applications and scripts that are used to access and control the databases. Users need to have the ability to run these applications but should not be able to edit or delete them as this is a task more suited for an experienced web designer. This means that the programs for MySQL must be configured and protected accordingly as well.

Network Risks

A MySQL database will provide a user access to other databases by allowing them to conduct activities such as connecting and making requests. Since the database contains information about user accounts, each one should be configured to only grant privileges to that specific account that needs to viewed or modified. A web host should also assign a username and password to the MySQL database to prevent unauthorized users from accessing someone else’s account.

We have compiled a list of defects within a MySQL database that may raise many security issues:

All files and directories do not have ownership configured to MySQL

Files and directories are not configured to be hidden from users. This gives direct access to third-party intruders

The MySQL database isn’t properly configured to run as a user’s main account

MySQL is being ran as a system root user. This will grant root privileges to a user and give them much greater access to sensitive files of the server

Most of the security issues that relate to a MySQL database are the result of poor programming. This all more a reason to reside with a reliable web host that has a documented proof of satisfied customers.
