How To Increase Security On Your WordPress Site

1. Restrict Access (.htaccess)

    a. Installing a plugin to help rate-limit login attempts is a step in the right direction.
    b. However a .htaccess file limiting directory/file access is likely one of the best.
        An example snippet of code is shown here:
       <FilesMatch wp-login.php>
        Order Allow,Deny
        Allow from xx.xx.xx.xx
        Deny from all

2. Do not look like a “new” WordPress installation

    a. Remove default posts, etc.
    b. Remove Version information in default files. This is done in two places:
        i. The first is the meta generator tag in your template.
           That is found in wp-content/{name of your WordPress theme}/header.php.
        ii. The other element is in your RSS feed. Open up wp-includes/general-template.php and look around line 1858. Find:
            function the_generator( $type ) {
               echo apply_filters('the_generator', get_the_generator($type), $type) . "\n";

        iii. Make sure a hash is applied next to the “echo” command so that it looks like this:
               function the_generator( $type ) {
               #echo apply_filters('the_generator', get_the_generator($type), $type) . "\n";

    c. Remove “Powered by WordPress” footers.
    d. Remove install or upgrade files
        i. Be sure to delete /wp-admin/install.php and /wp-admin/upgrade.php after every WordPress installation or upgrade!
           You don't need them for day-to-day WordPress functionality.
    e. Change some of the miscellaneous default settings
        i. Go to Settings > Miscellaneous in your admin console and change the names of wp-content/directory and wp-comments-post.php.
        ii. Make sure to change the template URL within the template and wp-comments-post.php accordingly, to maintain the function of your site.

3. Disable custom HTML when possible

    a. If it's not necessary for the form and function of your site, disable it. You can add the following to your wp-config.php file:
        define( 'DISALLOW_UNFILTERED_HTML', true );

4. Hide Indexes or limit access

    a. In a .htaccess file, add:
        Options –Indexes
    b. Make sure PHP source code is never revealed:
        i. Your site's wp-includes/ directory is the most important one to block. Find the .htaccess file there and insert:
            RewriteRule ^(wp-includes)\/.*$ ./ [NC,R=301,L]
        ii. If there are or will be subdirectories of wp-includes/, insert the following code for each one in the same .htaccess configuration file:
            RewriteRule ^(wp-includes|subdirectory-name-here)\/.*$ ./ [NC,R=301,L]
