Securing the readme.html file in WordPress is an often overlooked yet crucial aspect of website security. This file, typically located in the root directory of a WordPress installation, contains version information which can be used by attackers to identify potential vulnerabilities.
Leaving the readme.html file in its default location and accessible via HTTP can make your WordPress version public, offering a clue to attackers about which security weaknesses your site might have. It’s a small detail that can have significant implications for your site’s security.
To check if your readme.html file is accessible, try accessing it by appending ‘readme.html’ to your website’s main URL. If it’s accessible, consider moving, renaming, or deleting the file. Alternatively, you can set file permissions to restrict public access.
Using .htaccess rules is another effective way to restrict access to this file. You can add rules to deny access to the readme.html file from the web, ensuring that it cannot be viewed publicly.

While securing the readme.html file is a simple step, it’s part of a larger strategy to minimize information leakage from your website. Reducing the amount of sensitive information that can be publicly accessed is essential in a comprehensive approach to WordPress security.
Remember, securing files like readme.html is just one part of safeguarding your WordPress site. Regular software updates, strong password policies, and the use of security plugins form the foundation of effective WordPress security practices.
