recently I am interesting at apparmor, and I have read some docs of it, but I have a question that how to protect apparmor itself? I mean only if gained root privilege then stop apparmor service, all the protection will no longer effect, if I hiding or remove root user then how to remodify profiles if needed that because have not enough privilege.
Is there apparmor maillist? maybe you can email me: <email removed for obvious reasons>
This might sound really stupid, so you'll all have to excuse my lacking knowledge. I read that USB attacks get more and more common, like putting in an USB stick with a malicious autorun script on it, and it's game over. Can AppArmor protect devices and limit their access to the file system?

View 2 Replies View RelatedHere's my problem: Clean OpenSUSE 11.3 64 bit installation using default options into a Virtualbox virtual machine for pre-production testing. I want to check whether AppArmor is enabled, so I enter YaST -> AppArmor Control Panel.
This has a check box named 'Enable AppArmor' which is by default un-checked. I check this box, and then click 'Done'. This takes me back to YaST and I would assume AppArmor has now been enabled. However, when I return to AppArmor Control Panel the check box is deselected again.
depending on reading some apparmor docs, I know that apparmor read logs to determine what profile a program will be, that means a profile only can be built when the program have been exec at least a time, or we already how will be executed of a specific program. but if a hack inserts a bad-program such as a back door or virus what should never be executed any time, and at the same time we don't know what's the consequence will happen due to the behaviors of a bad-program. therefore, how could apparmor do to prevent these situations? Can apparmor confine every thing what under a specific directory by default? because use: aa-autodep /path/to/restrict/* is 'complain' by default and everything are allowed, can apparmor deny everything by default?

View 1 Replies View RelatedIn case this is a thread in the wrong section please move it to the right one. Following situation applies.I am using openSUSE 11.1 with modified kernel. Code:# uname -aLinux linux-2c5j 3.0.4-41-desktop #1 SMP PREEMPT Sun Sep 4 18:51:01 CEST 2011 i686 i686 i386 GNU/Linux The compilation did run flawlessly with the SAKC script.However the module apparmor does not load. Infact:Code:# modprobe apparmorFATAL: Module apparmor not found. I understand that I have to recompile the module, right? There I have the first question: wasn't the apparmor module accepted into the kernel (and therefore should be already compiled and available with the normal kernel compile)? Or is this wrong. How can I recompile the apparmor module for my new kernel.

View 5 Replies View RelatedCurrently the Apparmor program has the notification logs saved to /etc/apparmor/notify.cfg, however, when I try to save the notification after putting my email address in, I get an error saying "Configuration failed for the following operations: Unable to write config changes to /etc/apparmor/notify.cfg"looking inside the folder, I do not see any file named "notify.cfg" BUT I do see so files called reports.conf, logprof.conf, and reports.crontab. I am guessing that the program is asking to save the notification changes to a file that does not exist and in fact one of those three files are the proper ones to use. Well if that is the case then how would I go about fixing this error?
View 4 Replies View RelatedI have just reinstalled OS 11.2 but this time the 64bit system variant. I installed the real-time kernel and saw that the apparmor module reported an error and wasn't loaded. I have never looked into apparmor and only knows it has something to do with security, and thus I wonder if it is important to do something with this issue? I plan to use the kernel-rt and have more or less always used a variant of this kernel flavour, often self built. Though I can not recall having seen that error before and I have not used a 64bit system before

Is that too obvious?

View 9 Replies View RelatedInspite i have read through the sticky link but i have a query.
Example,
If you have your firefox under enforce mode in apparmor,are you still able to install an update / addon to it to a newer version.
If not,how to disable the apparmor in firefox.Is it as below?
Code:
So I activated the Firefox profile:
Code:
And restarted Firefox (even rebooted), but it doesn't seem to be working. When I open Firefox I am able to perform a "Save Page As" in locations I shouldn't be able to, like my Desktop or Pictures folder.
The following command says the Firefox process is in enforce mode:
Code:
Of the following lines, the only directory which is "rw" is /Downloads, why am I still able to write to other places?
Code:
OS: Ubuntu 10.10
Can someone with an active Firefox profile do this simple test for me? Click File -> Save As and try to save somewhere the Apparmor profile shouldn't let you, and let me know the results.
Tried the apparmor profile for Firefox. how to turn it off. No matter what I do, it still shows up as being on in apparmor status.

I followed this thread:[URL]...When I get to this part:sudo genprof firefox it does not work in the terminal. Is this still supported for Ubuntu 11?

Where is some good documentation with concrete examples on the best practices for how to update AppArmor profiles?
View 2 Replies View RelatedWhen I enable a new AppArmor profile that is not in the kernel, I've used this command:
Code:
apparmor_parser -r /path/to/profile

Code:
apparmor_parser -a /path/to/profile
Have I done something wrong by using -r instead of -a?
I am trying to use apparmor to restrict my file browser, which is Thunar to only let me view the files that are in the home directory and also removable media.I tried following the apparmor sticky with no success.I created the profile and tried editing it and it either started and let me do pretty much everything or did not start at all. Would it be possible for someone to help me step by step to set up a profile for thunar that would only show the home directory and removable media.
