Windows 7 To Dial Down UAC
Barence writes "Engineers working on Windows 7 have admitted Vista's User Account Control was too intrusive, and are promising to tone it down in the forthcoming Windows 7. 'We've heard loud and clear that you are frustrated,' says Microsoft engineer Ben Fathi. 'You find the prompts too frequent, annoying, and confusing. We still want to provide you control over what changes can happen to your system, but we want to provide you a better overall experience.' According to Fathi, when Vista first launched, 775,312 unique applications were producing prompts — so some may be annoyed that it won't be scrapped entirely, but at least Microsoft is listening. The comments echo those of Steve Ballmer, who admitted at a conference in London that 'the biggest trade-off we made was sacrificing security for compatibility. I'm not sure the end-users really appreciated that trade-off.'"
Of course most users are going to just click "OK", but how can the more tech-savvy users(you know, the ones who actually read the boxes) actually know what they're approving when the dialog boxes say such laughingly vague shit like "File operation - continue or cancel?"!
... how getting computer users to blindly click through continuous, repetitive, and annoying dialog boxes kept computers more secure in the first place. It would seem under any reasonable analysis to do the opposite.
If someone says he and his monkey have nothing to hide, they almost certainly do.
It would be a much better idea to force every programmer to run under a non-Administrator account (and no Administrators or even Power Users group membership either!) Anyone who complains is obviously writing bad code, since there is absolutely no friggin' reason that a regular application should require administrative privileges. Whatever you set during setup is IT! And, for God's sake, learn to open registry keys in read-only mode!
This problem of imbecilic prompts is directly related to the entire inane history of DOS and then Windows, where all the lessons of multi-user systems learnt decades before were wilfully and sanctimoniously ignored by the resident Microsoft "geniuses". Thus application "developers" were allowed to, and soon came to depend on, access to what in nearly every other OS in existence are "root only" subsystems. Even in editions of Windows which were supposedly multi-user capable, the prevalent lazy practice of majority of "developers" was to depend on system-wide registry keys, administrative privilege level processes and what not to accomplish most mundane of tasks.
And so now the chickens are home to roost, with literally hundreds of thousands of apps written to kindergarten competence levels. And Microsoft is in a bind: secure the OS and either break these stupidly written apps altogether, inundate the user with prompts every time one of them tries something stupid, or give up.
They are scared to death of the implications of the first choice, tried the second, and now seem to be heading toward that last one.
Does it really have to prompt me every single time? After prompting me to run the same program 5 times, couldn't it just ask me if I want to white list that program until the executable changes?

Perhaps I was not clear in my explanation.
In Vista, if you open the "all users" start menut and re-arrange 10 shortcuts, you get 10 prompts (actually, 20 - moves involve two prompts). In Linux, if you use the KDE/Gnome/whatever tools to reorganize the "start" menu, you get one single prompt when you save the changes.
In Vista, you also get prompts merely for viewing some information in the control panel. Then you get another prompt when you save/apply it, then another if you apply it again. In Linux, running the appropriate "control panel" tools requires no special privileges until you change something, at which point it prompts you once. And if you change something else without closing that window, you don't get another prompt.
I am guessing that the underlying difference is that Vista is confirming each particular action (system call?) whereas Linux is prompting for a privilege escalation which then applies to that process.
The biggest security problem in Windows is that the design of the HTML control and ActiveX in conjunction with the "security zone" model is inherently insecure. It provides a huge surface are to remote code execution exploits that simply does not exist in any other web browser... or any other software on any other platform that uses HTML and HTTP. The problem is that it's an explicit and deliberate mechanism for an object that should never be trusted... that is to say, a remote website... to request full local application permissions and run unsandboxed code.
Until this model is changed and only explicitly installed applications can run outside the browser's sandbox, Windows is going to remain the poster boy for "insecure systems".
Being able to prevent an already compromised application from performing system administration tasks is laudable, but it's not really all that important to the user. Everything on their computer that they care about isn't owned by the administrator, it's owned by their regular user account. And there's plenty of places owned by the end user that malware can hide to keep being restarted after the computer is rebooted. UAC is a partial sandbox, at best.
Being able to restrict what the web browser can do after it;s been compromised is laudable, but since the browser has to be able to save files for the user, it can still inject an exploit into the users account. So the reduced privilege mode on Vista (and the much touted sandboxes on OS X) are leaky protection at best.
And leaky sandboxes, and partial sandboxes, are more useful in providing a false sense of security to the user than actually keeping malware out.
Getting rid of the "security zones" model and replacing it with hard impermeable sandboxes will cause some disruption. Programs like Windows Update will have to be rewritten to use plugins. ActiveX games will have to be rewritten as flash or modified to run in a full sandbox using something like .NET or a JVM. But this WOULD be a matter of trading off convenience for security. UAC is trading off convenience for the illusion of security. That's not the same thing at all.
