Here are two of the most important issues surrounding WordPress security.

Webserver Security

Securing your server is most fundamental to securing your WP site. A secure server maintains the privacy and integrity of your data. A server running WordPress along with its software can have vulnerabilities, and thus, it needs to be ensured that your webserver and the software on it, are running on the latest and secure version.

Database Security

Database security is also a big concern if many blogs are being run on a single server. The best strategy to keep them safe and secure is to keep each of them in a different database with a different admin managing each blog. This can be done best in the beginning of WordPress installation.
This helps in genuinely securing your WP blogs. Even if a hacker is able to access a blog, he will not be able to crack all of them.
In the administration of MySQL database, make sure that it is properly configured and all unnecessary features are disabled, like accepting remote TCP connections.

Also, limit MySQL user privileges, as a MySQL database user requires only data read and write permissions for regular WordPress operations, like publishing blogs, posting comments, etc.

Thus permissions related to database administration and structure, like GRANT, ALTER and DROP can be repealed.
