WordPress Code Modifications
Since WordPress is an open source, the code itself can be modified by the user to create a unique and totally customized experience. In some cases, simply adding to the WordPress code can considerably add to the overall security of your blog. While this may seem to be done only by an advanced user or attempted by a programmer, actually, it is very easy to do.
If you are worried about the adverse effects to your blog, backup your blog before implementing any of these suggestions. If something does go wrong, or you simply don’t like the results, you can restore the backup and your blog can continue to run just as it always has. Even if you are fully confident in your ability to modify the WordPress code, it is a good idea to make a backup first.
Remove the WordPress Version Number
By default, the WordPress version is displayed in the head of the blog files and the RSS feed. If you are not using the latest version of WordPress, a hacker can use this information to launch an attack on your blog that exploits a known vulnerability in the version you are running. Adding a single line of code can prevent the version number from being displayed.
- Go to your Theme folder and open the functions.php file.
- Enter the code:remove_action(‘wp_head’, ‘wp_generator’);
- Save the functions.php file and refresh the page.
By just adding this simple line of code, your WordPress version stops being displayed where hackers can easily find it.
Change the Default Admin Name
If you have been using WordPress for a while, you probably still have the default username “admin.” Beginning with version 3.0, you could choose your own admin name. If you are still using “admin” to log in, it is time to change it. When hackers are trying to crack a password, it is more difficult if they also have to crack the username.
- Login to the phpMyAdmin panel.
- Choose your WordPress database.
- Click on the SQL tab.
- In the SQL Query Box enter:UPDATE wp_users SET user_login = ‘New Username’ WHERE user_login = ‘Admin’;
Now, you will be able to use your new username to login to your admin page.
