What can your business do to prevent your sensitive information hidden from hackers using Google Dorking techniques? There are many good security practices which would help keep your company information secure. Below, I have listed a few:

  1. Keep your highly secure information off your website. If your website is simply your public facing marketing brochure, there is no reason to keep sensitive information on your website. Public facing website are accessible to the entire world so limiting access to your sensiteve info is critical.
  2. Keep up with security updates. Following behind on your website security updates only makes your website more vulnerable. Think of security updates as a priority item to be addressed quickly rather than just someday.
  3. Penetration Test your website for common Google Dorks: Try penetration tests on your own website to see what comes up.  If you feel unsure how to go about this, enlist the help of a professional to examine your website for security leaks.

Together we can keep our websites and customer information secure if we follow good practices. The first step in employing good practices is to identify what information needs be kept private and make sure it is not accessible through the internet.
