DroidWall in the marketplace allows full WiFi access to all apps.
Is it possible to code an application for Android (perhaps with root access) that can:
- deny all outbound data access per app basis
- specify the rules (ip-range/port-range) per app basis
Like a real alternative to a desktop software firewall?
Way too many apps are leaking all sorts of information (in plain text!) from the user account database to the Internet.
The android security makes me really scared to use the platform for anything requiring security. The privacy/security model is basically a swiss cheese that can be poked through by almost any app that just asks for certain rights at install time.
I'm hoping a firewall would be able to limit this issue, no?
I don't know about the other stuff you mentioned, but my version of DroidWall has a block/allow option for wifi and 3g, separately. It's the latest version from the market place, 1.4.2
Thanks, I just checked it out and it seems DroidWall indeed has a Wifi side blocking by app basis as well. I'm still testing though.
Ah, just tried it. Force closes on Galaxy S (rooted). Sigh.
LBE Privacy Guard v2 is available, check http://forum.xda-developers.com/showthread.php?p=18948472#post18948472 for more information.
----------
First, my apologize for poor engish
Please allow me to introduce LBE Privacy Guard, a small app wrote by myself. This app enhances Android permission system and protects your privacy.
LBE Privacy Guard works just like Windows UAC, it intercept vital actions (like send SMS, call phones) and requests to access sensitive data(SMS conversation, contacts, phone location, IMEI, IMSI, etc) from apps, then prompt for your confirmation. Unless explicit permit, such actions and request will be rejected.
LBE Privacy Guard also has a low-level firewall, supports per-app control like droidwall, but not require netfilter/iptables so it works on pre-froyo devices and faster than droidwall because it doesn't filter packets.
So why I wrote this app? Because android permission system sucks, it's very hard for average user to understand the meaning of each permission, there is also no way to track the behavior of installed app and no way to control the permission of installed app(except uninstallation).
I hope my app could bring dynamic permission control and real-time track for installed apps. So you can figure out which app is stealing your privacy and block it before your privacy stolen.
Requirements
**NEEDS ROOT**
Works on Android 2.0 and above.
Tested on various devices and firmwares, but not tested on Android 3.0 and 3.1 devices.
Current Features
1. Block unwanted send SMS / call phone operation
2. Block unwanted access to phone location, contacts, SMS/MMS conversation database, IMEI/IMSI/ICCID/phone number.
3. Integrated low-level firewall, no netfilter/iptables required, works on pre-froyo devices

Good application, Thank you
im gonna give this a look. will report back if any issues
Been waiting for an app that watches local permissions.
Can you tell me what exactly is "low-level firewall." How can it filter network traffic if it does not make use of iptables?
Looks promising. Will give it a test ride for a few days.

hi traumatism, i would appreciate if you could tell me your phone model, and the ROM you are using.
It looks like LBE Privacy Guard has some problems to obtain ROOT privilege during auto start process.
Installing now, this looks interesting. I'll report any issues tomorrow.
Thank you.
edit: absolutely no issues, this app is awesome!
I was looking for something like this for the longest time... especially since my kernel doesn't support iptables. Installing now.
I am gob smacked, this application is brilliant!
Had it installed for around 2 hours now, no issues at all, works perfectly fine after reboot, doesn't appear to slow down phone or have any performance impact.
This should be included in Android by default!
Running it on HTC Inspire 4G with CM7.0.3
Great app. my first impression is good. looks like you've did a good job .. Thx happy
First look is great. Thank you. It is exactly what I am looking for

The "low-level firewall" does not filter packets, instead it removes network related supplemental groups of certain process. Without such supplemental groups, socket syscall will fail with EPERM, so the application will not be able to access network.
This solution neither require netfilter kernel module / iptables binaries, nor filter packets, it's faster. but it can't distinguish 3G and WIFI connections.
I love this idea! I haven't updated "att Mark the Spot" in months because they requested access to everything. The first thing was trust my root apps, sms, gmail & voice apps, then I blocked my phone ID from ALL apps. (would've been nice to have a "reject all" option there.) My question is, are there any legitimate reasons for an app to request my IMEI? Are there any potential negatives to blocking my IMEI from ALL apps?
Edit: I also experienced the force close on reboot, but LBE started right back up on its own. Atrix 4.1.83
eoc, are you planning to release the source code?
Hi guys,
I am a little confused by this app. Can it allow me to stop the imei sending to my carrier when I connect to the network? They are trying to reduce the amount of data included in my plan if im not using an phone!

No., It will only block apps and not the communication between your device and the carrier which is impossible on GSM networks.
Is anybody experiencing problems with blocked apps? Like fc or anything similar.

The latest Camera360 update demands a strange and dangerous permission - "Change WiFi State". This is defined as follows:
"Allows the app to connect to and disconnect from Wi-Fi access points, and to make changes to configured Wi-Fi networks."
The apps already has internet access. But change WiFi state means it can not only turn your WiFi on and off, but it can add or delete to your access points, and read/change other information like encrypted passwords.
I emailed the developer (in China) and they just keep emailing me back asking what version I am using. He obviously doesn't want to answer the question!
I've noticed this "permission creep" in many other apps. The latest Firefox Android app wants access to global system setting, address book, and accounts. The latest YouTube app can take pictures and videos without your knowledge.
There are a few apps that I no longer update. I also use DroidWall to block cameras and other apps from internet access.
Stay Away from Camera360!
I use droidwall as well, actually extensively. I block everything but the necessities.

Now that look at it, some of the permissions that Camera360's Chinese developers want are pretty scary:
https://play.google.com/store/apps/details?id=vStudio.Android.Camera360
Here are the most dangerous as of today:
NETWORK COMMUNICATION
FULL INTERNET ACCESS
Allows the app to create network sockets.
YOUR PERSONAL INFORMATION
READ SENSITIVE LOG DATA
Allows the app to read from the system's various log files. This allows it to discover general information about what you are doing with the tablet, potentially including personal or private information. Allows the app to read from the system's various log files. This allows it to discover general information about what you are doing with the phone, potentially including personal or private information.
PHONE CALLS
READ PHONE STATE AND IDENTITY
Allows the app to access the phone features of the device. An app with this permission can determine the phone number and serial number of this phone, whether a call is active, the number that call is connected to and the like.
SYSTEM TOOLS
RETRIEVE RUNNING APPS
Allows the app to retrieve information about currently and recently running tasks. Malicious apps may discover private information about other apps.
CHANGE WI-FI STATE
Allows the app to connect to and disconnect from Wi-Fi access points, and to make changes to configured Wi-Fi networks.
Camera 360 Browser Popups!
The Chinese developers that made Camera 360 removed the draconian permissions. But now, it has a more evil behavior. When you start your phone, Camera 360 starts a background process that displays popup ads on some websites with the default Android browser!
Thread on it here:
http://forum.xda-developers.com/showthread.php?p=33130018
Uninstall Camera 360 and watch your phone and your browser run faster!
Uninstalled :good:
Shouldn't this thread be a sticky, and, posted somewhere owners of all different models of phones will see?
Also, surely there must be some kind of app which lets you install apps without actually granting them those permissions? Some kind of permission stripper?
I'm not sure of any apps that control permissions directly but the is one called DroidWall which can block apps from communication over WiFi and/or your mobile network. Needs superuser/root access.

I have DroidWall, and Camera360 is blocked internet access. But it is still able to hook into the Android browser and show popups.
Not sure how that happens. You can try downloading AdAway from the market and see if that gets red of it.

Hey folks,
I recently installed NoRoot Firewall and found it really interesting to dis/allow network traffic without root. The app uses a local VPN to tunnel traffic and selective adjust the access. It needs permission for startup and networkaccess, the dev says it only needs this for rooting issues (see in-app explanation). The funny thing is, the app runs perfectly even without the INTERNET permission.
Unfortunately, the app isn't open source, the dev is a ghost and it hasn't been audited for security flaws. Although on a German blog, a security specialist has partly audited it for 30 minutes using Wireshark and network analysis. This resulted in no unusual traffic and no manipulations (instead of Mobiwol firewall).
My concern is: Is the app able to manipulate the traffic, that's rooted through itself, to point it or copy it to another destination? I ask, because it even works without internet and wasn't manipulating traffic in the test I read. And if really sensitive data is routed through the app and it's possible to ship this data cloned to another place, it's really disturbing.
I hope someone is able to clarify the technical background.

Doesn't answer my question, but it's open source in contrast to NoRoot Firewall.
I use XPrivacy and it works OK without any additional bakdoors.
It has even more functions (blocking permissions for apps) for privacy protection.
Very good question OP.
This is a extremely useful app but I also would like to know about the possible risks involved.
One would assume that removing the internet access permission (thanks for that suggestion) would render the app harmless but I can't be sure...
EDIT: After removing the app's internet permission with APK Permission Remover I found that the app does run without any error message but it won't allow any app to connect to the internet whatsoever. Which I guess is totally logical since all connections are routed through NoRoot Firewall...

Xprivacy cannot block Android system internet access, as that breaks your internet connection. Another limitation is that it cannot restrict android native apps. So, you need a real firewall to deal with that.
Noroot firewall is a horrible concept: your internet traffic is routed through some unknown server. Whatever you send though the internet is totally exposed to any kind of attacks/exploits. Plus, the issue of open source vs. close is totally irrelevant as applied to servers: so what if they open source their server? You will never know whether that server was built out of that open source.
The only solution is a real firewall.
Please stop listening to dopes who tell you not to root your device. They have an agenda: most of them are either advertisers, spooks or Google employees. The argument that a user doesn't know what he/she is doing and therefore should not have root is false: every known operating system on Earth (windows, mac, linux et al) provides root access/administrative rights to a user. So, how is that the same PC/MAC/Linux user all of a sudden becomes a dummy when it comes to a smart phone? The answer is he does not. But when he gets root, he can restrict advertising, spooking and spying by Google, carriers, advertisers and others.

From what I understand, the concept of NoRoot Firewall isn't routing your traffic through an external server but using a local or virtual VPN as a firewall. The Android VPN service is only used to provide control over your connections. This was explained on their web page which now seems to have disappeared. The problem is that one shouldn't just take their word on this and that's why it is relevant that this program is not open source.
There's an interesting discussion on the subject here.

If that were so, then why would users complain that NoRoot Firewall is increasingly being blocked by various services? That surely indicates a unique IP address, which is different from your mobile/wifi IPs. Android local vpn won't create a separate external IP address. I bet if you go to what's my ip, you will find a curious IP address.
I am always amused by people saying I am looking for a no root app when it comes to security. You just can't secure a system without administrative rights. This is like saying I need protection for my car, which has a habit of swerving around, but do it without using a steering wheel.

I don't know where you read that 'NoRoot Firewall is increasingly being blocked by various services' but maybe it had to do with the fact that you can't use a VPN service while using NoRoot Firewall because it already uses the Android VPN functionality as a firewall.
I also verified my IP adress online and it does not change when I use NoRoot Firewall.
BTW, I am rooted because I like to have full control over my Android but I haven't come across a root firewall app with granular control like NoRoot Firewall. Do you have any suggestions?
I attached a screenshot of the app explaining itself and its permission.

NetGuard is open source and very easily audited or checked - no Internet access itself.
It isn't as granular as other firewalls, but it has no battery drain, since the VPN service is only used for sinkholing traffic. So for now it's an all or nothing way to block an individual app from network access. There's more details in the thread, and the source is quite readable too.
Its using Vpn so its a power consuming app
Can anyone suggest best root app for restricting internet traffic to apps over wifi/mobile data. And also works as a VPN. The same option is there is noroot firewall. but from somehow from the above discussion, it is not 100% secure.

Some of us are just stuck with phones that are locked up tight and can't root to begin with. So I to am looking for a no-root solution. Before this phone I had all the others rooted, when it was an option. I came across this in a search because I just got a gopro, and the app creates a wifi connection between the gopro and the phone. Soooo, if I'm driving with the gopro, the phone, and all other apps think it's on wifi. So while I'm controlling the camera, other apps like Pandora, Amazon Music, and the sort search and search for a connection on that wifi network that's only between phone and camera, and won't resort to mobile data as long as that connection exists. Anyway, calm down.... not everyone has an agenda. Rooting is indeed relatively simple, but it's also equally simple for someone who missed one detail to ruin their phone. Anyone that ever asked me about it, I'd help them and give them a good "what you need to know" before I show them how to make sure they understand how important it is to read read read. If I get the impression they're a little impatient, or this kind of thing goes over their head, I discourage them from rooting. Just because I care and would hate for them to ruin an expensive device.
Hey folks,
I recently signed up in this forum, and I'm aware of it's professionalism. First, I was a simple observer because I wanted to try to understand the basics and it wasn't not a long time I discovered Android.
I installed NoRoot Firewall. My smartphone is rooted and I also installed LightningWall.
I blocked (with LightningWall) outgoing and inbound access concerning "NoRoot Firewall", and NoRoot Firewall is running fine.
Is it the good action to be sure that NoRoot Firewall doesn't export my data to an external server ?
Or it's not the good action because NoRoot Firewall uses a VPN ?
Sorry if my first post is too basic.
I hope someone is able to answer me.
Due to my recent installation of app Network Log, I have examined the I/O on the Net made by NoRoot FireWall.
It appears (by examining the log) that NoRoot FireWall is making I/O on the Net, but unfortunately I can't determine if those I/O are on behalf of applications crossing NoRoot FireWall (through Android VPN functionality), or for app NoRoot FireWall itself.
I don't know how to determine it.
If anybody has an idea.

I also blocked Noroot Firewall with LightningWall (input and output).
And I observed I/O made by Noroot Firewall in Internet, by using app NetworkLog (examining its log file).
I can't determine if I/O made by Noroot Firewall are really made by Noroot Firewall by itself, or for allowed app crossing Android VPN used by Noroot Firewall.
Is there a tool to determine it ?

Hello. Please excuse the necro.
A few questions please:
I'm not a networking expert. I do not understand the difference between the pre- and post- filters. Does it need to be redundant, ie mirror the rules on both filters?
How do you know if it's incoming or outgoing?
Also, why is it that even if there is a rule blocking a domain, such as *.domain.comort, I still see a connection being requested?

Install another FW dosen't make sense, because all traffic through NoRoot. The another FW can't recognize the network access by apps.

Hello everybody, i am using Graphene OS and only FOSS apps and i have a question. Recently i see some Foss apps also have "trackers" like Duckduckgo browser for example. I want to choose which apps i can block the internet connection for + the communication wich each other + VPN. I tried to use a "firewall" like netguard to block internet connection from the apps whoem don't need it + trackercontrol to block the trackers from all the apps and OpenVPN to hide my IP adress. But i can't use these 3 apps at once because the phone recognize them all as an VPN. Does anyone have the solution for this for me?

When you are on the Internet, data such as IIP address, browser type, operating system, etc.pp, are inevitably transported with. Even a VPN service - what is superior to a Proxy - get this data transmitted. And you never will really know what the VPN service is doing with these data - at least VPN services that are free-of-charge - and whether they themselves run Man in the Middle Attacks or not.
BTW: A Firewall protects a network’s resources from intrusion by users on another network such as the Internet. All networked and online Android users should implement a Firewall solution, IMO. If you have a rooted Android smartphone, you can use AFWall+ to control your device’s Internet activities. AFWall+ also allows users to control Internet access on a per-app basis.

Thabk you very much for youre great advice. So if i understand it good it is VPN connection is not a top priority right? Is it also true that GrapheneOs creates every day another imei number? Is the firewall solution of AFWall+ not the same as Netguard? If no can you please tell me what the difference is. AFWall+ gives in Fdroid that it has antifunctions, also for a lot of other apps. Does that have also influence on privacy and security?
I don't
1. make use of VPNs
2. know anything about GraphenOS. Changing IMEI and/or Wi-Fi Mac Address on a per daily basis makes no sense for me
3. use NetGuard, never tried it
