There is a great plugin called WP Security Scan that will check several possible security issues on your WordPress installation, automatically fix some, and let you fix others.Â After installation there will be a new link in the wp-admin sidebar called Security. Click that and you’ll get your recommendations.
Right now WP Security Scan covers:
-WordPress admin protection/security
Future releases will also address:
*one-click change file/folder permissions
*test for XSS vulnerabilities
*lock out/log incorrect login attempts
*user enumeration protection
