I'll follow up with more details on this in another post I'm working on, but just wanted to get some feedback from the community first to make sure I'm not totally misguided.
There are 5 security zones in Internet Explorer, specified in the registry: Trusted, Restricted, Internet, Local Intranet and My Computer.
You can explicitly manage membership for three of the zones (Trusted, Restricted, and Local Intranet). Anything which is not in another zone automatically falls into Internet.
How would you rank the zones from a perspective of trust?
