#5 Change WordPress Database Prefix

WordPress database contains many different tables that are responsible for storing every data in an organised and consistent way. Although WordPress handles the database itself, so everybody knows that it will have some predefined tables for it. These predefined tables have prefixes of “wp_table-name”. So, developers should also try to change these predefined table names to their desired tables and don’t worry you will not have to add any tables in the future.

  1. To change the prefixes of the table names, login to your PHPMyAdmin panel and select your WordPress database from your left side.
  2. Now Scroll Down to the bottom, select Check All to select all the tables.
  3. There should be a drop-down beside Check All option. Choose Replace table prefix from that drop-down.
  4. It will ask you for a From and To fields. Enter wp in From and “your-desired-prefix” in To field
  5. Click Continue

#6 Disable File Editing

In your WordPress Dashboard, there are options as Theme Editor and Plugin Editor. So, for the sake of WordPress protection, most of the developers always recommend that not to edit or add codes to the themes or plugins from there. So, why not disable them permanently? If you are a developer, then you will always have access to your files and folders or you can re-enable these options. But it could be problematic if someone else accesses these options.

To completely disable File Editing options from your WordPress Dashboard, you just have to paste the following code in your wp-config.php file located in your WordPress directory.

// Disallow file edit
define( 'DISALLOW_FILE_EDIT', true );

#7 Disable PHP File Execution

There is a number of PHP files in the WordPress Directory but what’s important is that still there are some folders that do not include any PHP files or no PHP files are executed from that path. For instance, /wp-content/uploads/ does not need any PHP file to be executed. So from a security perspective, why take a chance and leave any loopholes to our website?

So, in order to disallow any PHP file executions from a particular path, folder or directory, follow the given steps:

  1. You will need to paste the following code through a text editor.
    <FilesMatch “\.(php|php\.)$”>
    Order Allow,Deny
    Deny from all
  2. Now save the file as .htaccess file (not htaccess.txt) and upload it to /wp-content/uploads/

#8 Disable XML-RPC

XML-RPC stands for Remote Procedural Call which uses XML for call transportation. XML-RPC is used to process the call and fetch information from any third party domain, like an API, stylesheet or script, to your site. But it can also be exploited by sending thousands of requests or attacks in a short period of time, termed as DOS attack (Denial Of Service). Although it is useful for your site it is not necessarily be used for most cases, you can try to disable this service to prevent any of these types of attacks.

To disable XML-RPC, just paste the following code in your .htaccess file located in your WordPress directory.

# Block WordPress xmlrpc.php requests
<Files xmlrpc.php>
order deny,allow
deny from all
allow from
