Design Flaw #1: While the approach to determine if the PC is used at home or in a corporate setting (domain membership) seems like a sensible way, the fact that it is treating all interfaces as equal is not.
Sure-- but remember- [...] Regarding the RAS adapter dialing into the Internet, in that case, F&P would not be bound in the first place (when the connection was created).
I guess that's a well deserved black eye for me to take for not realizing that this default does treat interfaces as ...uhm... not equal. I shall concede that point to you. (BTW: How are existing RAS interfaces treated during upgrades? Are F/P bindings removed?)
Design Flaw #2: Multiple policies conflict in interface protection.
Not really "multiple policies" conflicting... It is an updated policy replacing existing policies at install time-- there aren't 2 at the same time... It's very easy to check out what settings are implemented for the FW in general, and for each individual adapter...
hmm... I'm confused. But perhaps I should drive the car before junking it. I don't have XP around to see how these two policies present themselves to the user. My concern is that there are settings in one place and settings in another, but no means to see the effective, combined settings in a single dialog. All too often offer systems immense capabilities for configuration (may I use the word configurability) only to leave the operator/user lost in all those choices. As I was saying, a simple and coherent configuration model helps security greatly. Perhaps you, Tim, could send me a screen shot with the dialog box that shows the current FW policy settings on an interface (or a link to a demo version of XP). Until then I only concede half a point ;)
I really should have been more clear about that- it sounds like "mitigating factors" junk.. I wasn't trying to sugar coat it-- I was directly responding to the claims in the article where they said "world readable, no password access" etc...
Oh, okay. I didn't know the article was talking about accessing the systems. I thought the issue was that the ports are unfiltered and exposed. Perhaps I need to re-read that article.
There is only one policy- everything is blocked, and you open what you need. I think some of the other posts may have confused that, but it really is pretty easy...
Ah, I see. Good. Easy is good. Not just for lamers like me :) but if a system is made easy to configure and use, then there are less threats to the security of that system. I'll make sure I have a copy of XP in front of me before I yell again... ;) Later dude. Frank
