Adding more security zones to Windows (Internet explorer)

07/19/00

page 1/2


Overview:

Security Zones exist in Windows to allow you set different security settings for different domains. For example, if you wanted to disable Active Scripting, say, on all internet sites, you can do that through the internet zone. If you then found a site for which you wanted to enable scripting, like Microsoft.com. You could enable Active Scripting in, say, the Trusted Domains zone and then add *.microsoft.com (the * is a wildcard character) to the Trusted Domains zone.
*NOTE: The above scenario is HIGHLY inadvisable.
Windows/Internet Explorer 5 by default comes with 4 zones. This may limit your options if you want varying levels of security for different web-sites. In this article, I'll show you how to add as many new zones as you want and modify them to suit your needs.


Let's get this party started:

Actually, before we get this party started, the usual disclaimer applies:

You're about to mess with the registry. The chnages you make are immediate and COULD (if you're mental) render your machine inoperable at worst - requiring you to reinstall windows and your programs. Please back-up the registry before proceeding (if you're a wuss).

OK. The security zones panel is accessed through Internet Explorer by the following: Tools | Options | Security Tab. This is how the security zones panel looks by default:

You can see the four default zones: Internet, Local intranet, Trusted sites and Restricted sites. (technically, there are 5 zones as we'll see, if you include the "My Computer" zone, but it's not that important). Compare that with what the settings look like after we add a new zone:

I've circled the additions. I named the new zone "Our newly created zone" and changed the information message to read "This is the new zone we made." This stuff, as well as the Cartman icon are all customizable by you. You ready?

How it's done:
1. Open Regedit:
Open up the Registry Editor (regedit.exe), (you can simply go to | Run and type regedit).

Once in Regedit, navigate to the following key:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones]


2. Select a pre-existing zone to copy(export):
You should see something like what's on the left: Here you can see the 4 zones (zone 0 is "My computer").

Now there are many ways to proceed. The easiest I've found, was to do the following: Take a zone that already exists, export it out of regedit, use a text-editor to rename the zone and give it a new name, then import (merge) it back into the registry, thus creating a new zone. Here's how it's done:
