I would argue the opposite :)

One of the handiest features of Windows Firewall is that you have the option of "Displaying a notification" when it blocks a program, and when the dialog shows up, you have the option of granting that program access, and then it never bothers you again.

I do agree that the way it was done in Vista was absolutely horrible... but a one time "Let this program do this" works VERY WELL, and I think it gets around all the problems you mentioned.

In my opinion, the lack of this is the single most obvious failing in Android.

I think there is enough evidence that asking permission at time of need doesn't generally work -- see the MIDP experience, Windows Vista/7 security, etc. There is a fundamental problem that at the point you ask the permission, the user is wanting to accomplish some task at hand, and all you are doing is bugging them.

And it gets much worse when you consider applications being able to run in the background. Do permission requests pop up on users from the background? Does a notification get posted that they respond (or not respond) to at their leisure?

If you have a wall of permissions, the first thing I would suggest is looking at those and seeing if you can trim it down. In fact, doing things that make it easier for apps to make use of lots of permissions are to me counter-productive -- it is a good thing to make lots of permission use a harder road.

I just had a look through the apps installed on my phone, and the *vast* majority of them only require a couple permissions. So someone who is using a large number of permissions is going to stand out from what user's normally see, as well they should.

From the platform side, we also need to avoid making it easy to have lots of permissions. We need to be continuing to design the platform to reduce the permissions that apps need. For example, the window flag to keep the screen on avoids the need of the power manager permission for most applications; we should beef up our intent interactions with the contacts app so applications can work with the user to select and modify applications through that without using permissions; etc.

Sincerely,

Brad Gies
