You can never be too security-conscious with WordPress, so let's look an excellent security plugin: WP Security Scan. I found out about this plugin from the WordPress 3: Developing Secure Sites course on LinkedIn Learning.
This plugin does several things, but I especially like the initial scan, permissions scanner, and database prefix changer.

Provides a quick scan of your site and makes security recommendations.
Checks directory permissions to make sure they're set properly.
A common security-through-obscurity tip is to change the database prefix. I used this plugin to change the database prefix for several sites, and encountered no trouble. Still, make a backup first!
This plugin integrates with WebsiteDefender's online services, which I haven't checked out. Luke Rumley, a fellow member of WordPress Grand Rapids, told me that they provide downtime monitoring like Pingdom.
