Why it is Hard to Whitelist Websites and How Comodo Helps

Whitelisting is different than blacklisting, in that whitelisting blocks everything and then allows a few things later. With that definition in mind, everything is automatically blocked and cannot be used. Administrators go in and create a whitelist so that certain things can be used. With a blacklist, you are allowing everything at the beginning and then blocking things as you see fit.

At Comodo, we understand that it can be difficult to whitelist things like websites, but also know that it is a necessary part of business. You don’t want your employees wasting time, but you also don’t want them to inadvertently open the door to hackers, malware and viruses.

Why Whitelisting Sites is Hard

While more and more companies understand the benefits of whitelisting, it doesn’t make it easier for administrators. There are many non-obvious domains out there, making it necessary to do more work. However, the work only has to be done once and then everything is set up correctly. For example, in the past, you would link together the www part and make your entry so that HTTP or https would be included. If employees neglected to type in the HTTP, https, or www, it would still work correctly. Now, things are more complicated because sites can have different sources of information on different servers or domains.

An example would be ebay.com. If you sell things through this website, you would have to add multiple items to the list, including:

  • Facebook.com
  • Ebay.com
  • Ebay.ca
  • Ebay.com.au
  • Ebay.co.uk
  • And more

Facebook would need to be added because you may want to like something and there are so many other sites associated with ebay.com, such as Paypal. Our product makes it easier to whitelist websites, because we can tell which ones are associated and you can add them, as well. Contact us to learn more.
