Change Your Database Prefix to Improve Security

Posted by on

One of the awesome things about WordPress is that it’s a dynamic publishing system that uses a database to store your site’s information: posts, options, plugin and theme settings – all of this data is stored in your site’s database. It’s like the brain of your WordPress installation. Unfortunately the WordPress database is also a prime target in many website attacks. Spammers and other bad guys target various database tables with automated scripts, SQL injection, and other malicious code. Needless to say it’s critical to protect your database and keep recent backups. One of the smartest ways to protect your site’s database is to change the default table prefix to something obscure and difficult to guess. Sort of like a password.
