How Employees Get Around Your Firewall
You may have spent big bucks deploying a firewall at your business to keep employees task oriented and away from those online sources of fun, I mean distraction, but necessity is the mother of invention and chances are good they are still accessing sites you've blocked.
With virus scares running rampant, you're wise to install a firewall, but here are a few ways your Web workers may be getting around it that you may be interested in knowing about:
- Using an IP address: If you implemented domain name based access restrictions, end-users can still bypass the firewall by using the direct IP address. For example, you have reason enough to block youtube.com, but their IP address is 220.127.116.11 and end-users can access it directly by copying and pasting it within their browser.
- Using an Anonymizer: There are services online which help people surf the Web anonymously. What happens essentially is that users access a third party which routes user requests through the providers server. Most of these services are commercial but users will pay if they need to. Some popular anonymizers are proxify.com and of course anonymizer.com.
- Using a public proxy server: A proxy server acts as a buffer between an end-users computer and the Internet resources they are accessing. Proxy servers accumulate and save files that are requested by Internet users in a special database, called “cache”.
