WordPress Database Security is the most important thing. Every single piece of information stored in it, which makes hackers and bots to target for stealing information by applying SQL Injection.
WordPress Database uses a default table prefix value “wp_” for all of its database tables. Typically, every website that is running WordPress will have its database tables with this prefix and this can surely be used by the hackers or malicious bots to guess your database table names. That’s why the smartest thing to do while creating a WordPress website is to change the prefix of the database, which can be done easily.
