Windows Security Through Annoyances?
techmuse writes "According to News.com,
Microsoft's next version of Windows will let you know that you are looking
at (supposedly) secure data by putting personalized text, such as the names
of your dogs (a null list in my case), in window borders, and will also hide
the data unless the window has no others on top of it. That should make it very usable, and speed adoption of security features -- especially among
people who need to be able to see the data in two partially overlapping
windows at once."
How is that more secure than the little combination lock icon?

Graphics cards are a security problem, because they contain their own pool of memory.
MS could just drop support for all video cards that have their own memory in favor of ones with integrated or shared memory (a la i810 family). Then the OS can have direct control over every aspect of the cards memory because it actually resides in main memory.
the window borders thing isn't a bad idea, but as for making content disappear in the background... "hullooo, earth to microsoft"
All I know is, I'm not buying Longhorn; I don't need MS holding my hand wherever I go. This seems like just another "feature" where something can go wrong...
Not much now, because people aren't expecting everything to be so secure. In the future, when it's expected that what you're looking at is secure, attacks like this could be come more widespread.
While I agree that security should be easy, you can only dumb it down so much. If the entire knowledge that the user has is that a window is "secure", they are only getting a warm fuzzy feeling, not real security.
For real security, you need to know WHAT has been secured. Examples include:
Data was encrypted in transit.
Data is authenticated to come from XXX source, according to YYY certificate authority.
This window is protected from being viewed by PCAnywhere.
This data has DRM, and is protected from being copied to another computer.
Unless you tell the user WHAT the security is, they will make poor decisions about what to do with the data. Putting the name of their dog on the window doesn't provide that information.
How does vanishing data from a secure window when its not on top anymore makes the data substansially more secure? If anyone has allready hacked into that system it maybe safely assumed that he has access to memory... I agree it is safer in case you are watching porn and someone walks into the room...but in real business world people view confidential information when they know that there is no one to look upon their shoulders. IMHO this is just another gimmick ....."OH look I have a secure window!! I dont care if I open this strange looking attachment that came by email .....ZAP!!!"
All your pets' names are belong to Microsoft?
Seriously, given the number of people who use a pet's name for a password, displaying a list of them on the screen seems like a huge security risk.
Furthermore, I think that this could turn out to help security much more than some obscure feature. It is this low-level, "no shit sherlock" kind of basic security that is much more needed.

It is fundamentally possible to target the weakest link of any security system. If I cannot create a lookalike window, then I just have to trick Windows into doing that for me. For example, the mere fact that I have an SSL certificate does not mean that you are safe submitting your credit card to my site, although it means you know who I am and can contact me or my company if something happens. SSL requires, in order to be effective, a visible address, and a popup window with no address bar has no way of verifying the address for the customer ;-) So I already have a way of attacking this trust and at least making it hard for the user to track me down.
;-)
Tricks like these are not addressed by this approach which means that Microsoft still hasn't learned that con artists are probably the most likely to be able to get your confidential information

Hmm, okay, so let's say I make a Microsoft-ish spoof page with a border that has "king", "snoopy" or "brutus" all around, and half the visitors will recognise their page with their unique pooch's name on it, and will give me their credit card number in total confidence. Hmmm ....
I was thinking that too. Then I read the article:
"A hacker can create a spoof page with dogs' names running along the border but, in all likelihood, not one reading "Buffy, Skip and Jack Daniels--and in that order," Biddle said."
True, but anyone could just create a similar-looking window, and just put words "Secure Window" instead of "Buffy, Skip and Jack Daniels". Guess which one will look to be secure and which one will not.
Also, if this system is not clearly explained to non-savvy users (and I am guessing it will not be), then there will be other implications as well - such as people typing in their passwords, or realizing their pet name *is* their password, etc. I look forward to how they implement this and confuse users.
