Hey mates.
Im looking for a wm 7 alternative to the quite nice app protector android app called Smart App Protector.
What i need is the functionality to restrict my wm7 devices so the users cant enter IE, Settings and other functions than those i want them to.
When a user tries to open the browser on a android device with the smart app protector installed, they get prompted for a password, which is exactly what im looking for.
If there isnt an app that does what im looking for, does anyone know a way to restrict at least internet trafic in IE, i still need data connections, but the users wont be allowed to use data except for 1 app.
My first impression of the wm7 - 7.5 is that its very restricted compared to Android devices :S
Thanks a lot for your help.
A quick for-the-record: No such thing as WM7. Windows Mobile is dead. Although some of the underlying code got re-used in WP7, the upper part of the Windows Phone stack is completely new, and the low-level stuff has changed considerably as well. What you're asking for would probably have been quite easy on WinMo.
On WP7, it's a lot harder. There are three ways I can think of. The first and simplest would be a well-modified custom ROM. Another is to modify the policy system to prevent launching iexplore, settings3, and similar programs, but have an app that (once the password is provided) allows changing those policies. Note that we don't yet have full control over the policy system (as a community; Heathcliff74 knows quite a bit but is busy with his Root Tools project). The third would be to try modifying the registry entries for certain operations. The effectiveness of this depends on whether apps are launched directly (by executable) or indirectly (by GUIDs in the registry). If it's the latter, the launch request could be routed through an authorization app first.
Bear in mind, the only one of these changes that is permanent is a custom ROM. Otherwise, the user could hard-reset the phone (losing all data on it but bringing it back to factory default configuration). It's possible to hard-reset just using the buttons; you don't even need to use the touchscreen.
Thanks for the correction, WP7 ofc
Im rather impressed by the performance of the OS so far, but it has many unforseen restrictions for my needs.
Since i only had the windows phone 7 for 1 day so far, i dont have much knowledge about changing what you are suggesting.
I know what you mean, but no idea how to do on WP7.
A custom ROM would be great indeed, but i dont have any experience in that field. Would be great to get a nice configuration tool with a gui to make the needed changes and then a tool to upload the new ROM to the phone...in that simple order
Im also looking for a solution to install software that was supported by windows mobile. Im checking out cheronwp7 at the moment to see if that can do the trick.
It seems a lot like WP7 is 99% consumer minded than business minded compared to old WM, a bit shame imo.
Hello everybody,
I am currently using an android phone and consider to switch to WP8 after it has been release due to better hardware concepts etc.
I already read that WP7 apps are executed in a sandbox and therefore the whole process aint to be more "secure". Anyhow, Iam not concerned about a virus or malware.
My biggest aim is to keep my data private and to secure my privacy.
Regarding WP7 I could not find any hint about that topic. I cannot imagine that nobody cares about this topic around this OS !?
What I want is the following:
Set for each app what it is able to access (e.g. Access to contacts, location etc.)
Control internet access for each app
Maybe it already exists and therefore nobody talks about it, maybe it is technically not possible.... Just want to know
Thank you in advance for your help.
Regards.
WP7 (and presumably WP8) apps use a "Declared Capabilities" model for controlling access to resources like you mention. That is, if an app wants to access the network, it must declare ID_CAP_NETWORKING in its manifest. If it wants to access your contacts, it must declare ID_CAP_CONTACTS... etc. When you view an app in the Marketplace, you can see what capabilities it includes.
However, there's not really any fine-grained control over such things. For example, if you install an app that wants access to your contacts and your appointments, you can't tell it "OK on Appointments, but no Contacts access" short of modifying the app prior to installing (and if you did that, there's a good chance the app would crash when you ran it). Similarly, there's no user-controllable firewall on the phone; an app that specifies ID_CAP_NETWORKING can access anything that is available on the network.
I believe this is similar to the behavior of stock Android ROMs. The advantage that WP7 (and presumably also WP8, but it's too early to tell) has over Android in this regard is that apps go through a much more extensive review process. If an app needs to access your contacts, for example, it better have a good reason for this access and and it will (well, should) be rejected if it sends them off to some advertising company or something.

I see. So basically this means, that I could edit the manifest file of any application myself and set the level of access I want it to have, but the application will probably not work anymore.
For instance, I have an navigation app that wants access to my contacts to offer me a direct navigation option to my friends place as well as internet access for current traffic information. Do I need to trust microsoft, that they reviewed this app so well that it does not send my contact list to the software company ?!
Moreover, this way I cannot prevent microsoft for example to collect whatever they want from my phone, right ?
It is correct, that stock Android does not offer this function, too. However there is the possibility to root it and have apps installed that control all traffic, even those of the OS itself.

Yes. Applications are expecting to see all CAPs they request, as this is an all-or-nothing thing in WP. If you'd edit their manifest, the application could behave arbitrarily, and it would likely crash because an essential assumption it made - that being either it has the CAPs it requires or isn't installed - isn't applicable anymore.
Moreover, this would require at least a developer unlock, for some applications (for instance Skype) an interop unlock and for some applications (all XBL ones at least I think) a custom ROM.

Yes. There is no way to partially grant permissions.

Microsoft makes the system. If they wanted to hide something in kernel mode, and wanted to hide it from all user accessible APIs, this would be easily done. Simply spoken, if you question Microsoft's commitment to their EULA, WP is the wrong OS for you.

Without a kernel built from trusted sources, hiding data streams from all APIs is always possible for an OS maker.

A custom rom, unlocking etc. is not an obstacle as long as it is possible and serves the purpose
In general I would assume, that any application should be able to run without an internet connection, since it could be possible that you are just not connected to the internet for some reason ?? Therefore, removing the CAP for internet access by editing the manifest file should not lead to any unwanted behavior. Or is it more like that, that all apps check their CAPs they requested on startup and not only when they want to access some ressource ?
This way it would be possible to remove internet access for any application I do not want to send data somewhere without blocking others and without the necessity to remove other CAPs.

Generally spoken, I trust nones commitment to any EULA or something. Microsoft, Apple, Google, they all have such documents and every few weeks something comes out that they are tracking you, (anonymously ) etc. Everytime the answer is something like "oh, what a mistake, of course it was not intended to be..."
Of course I do want have the comfort of a smartphone, a tablet pc or a computer, but I want to perserve and control my privacy to such an extend that I am satisfyed with it.
Even on a Windows computer I have got the possibility to control network traffic, to limit access for certain software etc., even to limit access for the OS. So why the heck nobody is interested to have that on a smartphone, why an smartphone must be an free bazar of private information everybody can have and do what they want with it ?
What I want and hope is, that with WP8 (since it will be the same kernel than the PC version) something like that will be possible. Just like on a Andriod phone, too where you can grant internet access for everything, even for system components individually.
Removing ID_CAP_NETWORKING will result in an exception (access denied, essentially) when the app tries to call a networking API. Since the app is probably not expecting that particular exception, it will probably crash. Some apps may have very broad exception handling on their network code and simply assume that they don't have access, though.
You don't really have any control like you describe on a Windows computer. You can set the firewall, sure, but then you're trusting Microsoft to not have some leak or backdoor in the firewall. You can write your own drivers to hook it at the kernel level, but then you're trusting Microsoft not to have a direct access to the HAL that bypasses the network driver stack. You can re-write the HAL (OK, not practically, but let's say "you could install another OS" instead) but even then you're still trusting the manufacturers of your motherboard, your CPU, your network interface hardware, your router, your modem...
At some point, you have to trust somebody. A big, publicly-held corporation with many users, a clear privacy statement, and a lot to lose if they screw up fits the bill is your best bet in most cases. Microsoft fits that bill just fine.

Ok, what should I answer ? If you use arguments like that you can extend it to what ever you want.
At some point you need to be realistic when looking at security and privacy. There always can be/is a way to bypass systems on a low level basis to do what you intend to. So what ? You cannot pervent this in any OS.
But when using a third party software firewall that comes with its own drivers, you can be sure to certain extend that you have your networktraffic under control.
This is actually not the point I wanted to make about WP7 and probably WP8.
I understand, that for example an navigation app wants to have access to your contacts to offer you the option to navigate to your friends place. I also see, that this app wants to access the internet to get traffic information. But I do not want this app to have neither access to my contacts nor to the internet since I cannot know what data will be transmitted to the software developer. I even to not want them to do some statistics with me gps positioning. NO. as simple as that. What I do with my information is what I decide.
So what I especially do not like is, that most people in the world do not care about such facts at all. They are running behind apple like lemmings, willingly giveing them all information they have and being happy that everything works so fine on their device !? What the... ?
Anyway, it does not matter, my questions got answered, I will have a closer look at WP8 when it is out and see if it possible to keep my stuff under my control or not.
First of all, EULAs are a binding contract for the first parties, which means that if such a thing were to come out, and it is not a very obvious (actual) bug in the software (Apple's local geolocation data retention bug and Microsoft's bug in WP7 that may have determined the location before you pressed "OK" in the dialog are definitely such - they give nothing of advantage to the two companies), they have a problem named "breach of contract": There will be legal action by activist in such a case.
Then, your argument is valid, a firewall would be effective if you trusted the hardware and software environment. However, I wouldn't hold my breath for it: Firewalls or capability removers are just not fitting in the image of a smartphone. On Android, you also require root for this (important point here: a 3rd party device unlock, it does not come built-in - and apps could also stop working if you withdraw rights from them, since the code might not be prepared for such a scenario either), on an iDevice and Windows Phone it's not possible. It's very much the contrary of how smartphone makers would like to market their devices, a scenario where you might possibly not trust your apps - this could even scare users away from smartphones.
Therefore it is unlikely that WP8 will come with such a capability built-in. Even though WP8 will be sharing the kernel with WinRT, it should be noted that both, WP8 and WinRT will require mandatory UEFI Secure Boot from OEMs. It's likely that this cannot be broken at all unless every a very significant hole can be found that permits to breach the chain of trust or the devices' firmware can be attacked. Hence, it isn't even said whether WP8 can be rooted. If WinRT does not come with Windows Filtering Platform (WFP), it would be the same situation as is on WP7.
You are right, of course the EULA is the first thing to mention But about what legal consequences are you talking ? They will be fined to pay some million dollar ?! Ok, nice, but they still have my data. In this case they bought the information, that's all.
Anyway, I do not want to be paranoid and of course also here at some point you need to stop
To have root access on a device that you own is natural for me. I bought it, it belongs to me, that's why I should be the master on my device. For sure, this does not fit in the global tendency of "not to care about your device, just make it run", too.
On a windows computer I can have administrator privilidges as well. Why they do not want to give me this on my smartphone that claims to be a computer somehow, too?
By the way, WFP is quite a useless piece of invention. I once experimented with WFP for some software project on a windows computer and found out, that the same way I can change every rule someone created for the firewall, everyone else can do. Means: I created a rule to pervent skype to access the internet. Guess what ? Right, Skype detected that and 2min later it deleted my rule and created an own one to grant access again. What use does such a system have ?
There's a rather simple reason, "root" is a badword for most mobile manufacturers: piracy. On Android, that's a different story because you typically can install side-loaded applications, but on the iPhone or Windows Phone you require unlocks to pirate. Typically, piracy is not a practical option on them until you have a root unlock. (If you take a look at WP7, you either require an interop unlock or a custom ROM to have more than 10 unsigned apps - if you wanted to pirate, that would impose a very tight limit on the extend you can do such. Students are even limited to 3 unsigned apps). Root is something that circumvents the control systems of the manufacturer - something that neither Microsoft nor Apple have interest in.
WP and iOS have - compared to Android - very low piracy rates, so this is paying off. (For that matter, WP is probably more locked down than iOS: It took 8 months to public availability of an unlock for my HTC Titan; iOS is usually broken much faster)
I think you're confusing Windows Firewall with WFP. The latter is just a programming interface in the network stack, which allows applications to inspect, filter and modify packets in the network stack. It does not have any rules you could set therefore. Windows Firewall comes with rules, and Skype will - if it has proper privileges to do so - attempt to automatically permit itself in the Firewall.
About the EULA, no. In literally any modern country, data found to have been obtained illegally will result in a sentence to delete the data, to pay a fine and likely to pay the victims damages.
You see, that is the point. The possibility to decide upon your own device is taken away from you due to fears and prejugdes of the manufacturer. Why it always must be connected with piracy ? It means that everybody who wants to have root access on his device is potentially criminal and therefore it is better not to ask for it. Nice.
If you buy a modern house with automatic controlled sun blinds, heating etc. Would you accept, that there is a control room in your cellar, where only the company that built your house has access to? You are only allowed to switch on and off the light in your house. Even the sun blinds open and close whenever they want and tell you when you are allowed to look out of the window and when not. Just because you have no "root" access to change that and you need to accept it.
Fur sure, it is nice to have such system where the user has not rights since most users are not experts and causing mostly only problems where in the other way the system runs smooth and stable...
About WFP, yes I just saw that with Win Vista and Win 7 they introduced such way of filtering platform. I really mixed it up with the windows firewall manager that is accessable via API.
I never saw in any case where data has been found somewhere that users got paid damages. Did Apple do when they tracked their users ? I think no. Did they delete the data ? No they did not, they excused and said something like "oh, what a pitty, we will change that in our next update" Quite safe, isn't it ?
What you fail to see is that android is riddled with issues due to its openness, it is suffering in exactly the same way WM did, you may laugh of WM but android owes its roots to WM. Apple and MS saw the issues, and did something about it.
Yes that restricts you, but you and those like you, are a tiny minority, simply put they have bigger things to worry about, and that is average jo an jane blogs. they do not need that level off access and giving it to them is one of the reasons 10,000s of computers out there are nothing but bots used for DDOS attacks
Remember, WM was slated for being buggy and slow, the reality was far from that, but the networks and OEMs had so much control over the OS they literally screwed it sideways and the magic effect was that they didn't even get the blame, MS did! (ring any bells with android!)
Why didn't WP take off as well as it could have? easy, because firstly it didn't have cool roots to an ipod, secondly because MS tightened up on the OS so much it pissed off the networks, im sorry to say, its little to do with apps and side loading, that's just the first thing people think of when they are talking about something they know nothing about.
Networks like to do things their way and I think you will see their influence in WP8 a lot more, and because of that more than anything else, the networks will like it more, if they like it they will sell it, then you will see a larger uptake in it and thus more apps
anyhow, that's off topic, fact is this, security will only get tighter and rightly so, as much a that is a pain in the arse for you an I, that is the reality, you may have perfectly legit reasons for full access, but I can promise that most who want it probably will use it for something dodgy, MS and Apple can not afford to have a time bomb on their hands in the shape of android.
I fully agree with you !
Just for the protocol: I liked WM very much and I never considered it as buggy and slow, but ok that's another topic.
The reason why Iam using android at the moment is quite simple. There was no satisfying hardware available for any other system. Iphones are useless, for WM almost nothing was there that could be used as a smartphone and WP was likely to be replaced by something else. I was waiting for years that some manufacturer releases a smartphone that has a 2.3" display like a normal mobile. I hate those laptops people try to use like phones with 4" display and what ever.
Since Iam quit unsatisfyed with the quality of my sony ericsson mobile, Iam looking forward to get a Nokia phone again. Moreover, Iam really no fan of open source software since compatiblity is quite bad and the functionality is mostly not really reliable. Iam a heavy MS Exchange user and I do appreciate nothing more than be completely synchronized with my phone laptop and everything. Only WP8 can provide that... So, Iam dealing with it.
