I have a program that generates large amounts of apparmor log messages. I'm happy to enforce restrictions on the program but I really don't want it to fill my log with messages every time it attempts to read a file.
Is there a way to let it enforce restrictions but not log denials?
Since Ubuntu 9.10 I used:
"sudo apt-get install apparmor-profiles
sudo enforce firefox"
However in Lubuntu 11.04 the "sudo enforce firefox" command does no longer work. It looks like the enforce command is no longer recognised.
Is it possible to create a selinux profile for a program like with Apparmor?

View 9 Replies View Relateddepending 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?

I ran and installation and the program opened up automatically but I can't find the program executable.
If I could find a log then I could locate this file.
prohibit execution of any program include shell command, only be profiled program could be executed, can apparmor do that?

View 4 Replies View RelatedAnyone set up an Apparmor profile for Firefox?
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.
View 3 Replies View RelatedI'm trying to understand the Apparmor and would like to get FF profile from Bodhi.zazen [thank you],but I'm kinda new to Linux.Did lots of reading but missing one thing:
1.where is FF profile? I can't see any usr.lib.firefox-3.6.12
2. how do I do copy FF profile from Bodhi.zazen?
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?
Also, I installed the profiles. Is something supposed to happen now or do I need to configure them?
sudo apt-get install apparmor-profiles
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
But when I recently read the manual for AppArmor, it says to use this command for new profiles:
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.
View 2 Replies View RelatedIt seems that AppArmor can't be effectively used to protect read access to files from users (including roots). It is possible to create a profile for, eg, 'cat', but then the users can use 'less'.Is this true? Should use SELinux instead for this?
View 5 Replies View Relatedi was trying to edit my firefox apparmor profile. I used aa-genprof, and accidentally closed the terminal before the program was finished. Firefox wouldn't load properly after that whenever it was enforced. I uninstalled and reinstalled the profiles, but it didn't help.Finally I deleted the files for the profile itself ... now it will not reinstall them..I marked all the apparmor packages for complete removal and then reinstalled them but it will not put the original firefox profile back in.
View 2 Replies View RelatedThis page [URL] shows how to enable apparmor firefox profile. Why isnt apparmor firefox profile enabled by default? I would postulate that this would be because there must be some limitation by having the profile enabled. If so, what would the limitation be?
View 9 Replies View RelatedI've read and re-read everything I can find about AppArmor, to no avail. On the whole, AppArmor isn't for me. However, rather than give up on it completely, I have an idea: create a profile that I could use as a template for any untrusted application, with the aim of 1) blocking it from network access and 2) blocking it from installing other applications. I've got as far as creating an empty profile:
Code:
# Generic AppArmor Profile for UntrustedApplication
#include <tunables/global>
/usr/sbin/UntrustedApplication {
#include <abstractions/base> }
What do I need to add to make this profile 100% permissive, except for the two exceptions stated above?
I use Ubuntu 10.10 with encrypted home. I'm new with apparmor. My firefox-3.6.13 is now in enforce mode - with standard profile. With this profile it should have write access only to:
owner @{HOME}/Downloads/* rw,
But I can save files (with standard downloadmanager of firefox) e.g. in $HOME itself and I can't find any other rule, which could allow that. I have thing, that ecryptfs workaround just affects the eCryptFS "part of things" and limitations of normal filenames/paths (in mounted ecryptfs) are still possible. Why can firefox write elsewhere as in to ${HOME}/Downloads? I get also this in kern.log (but not by saving a file as wrote above):

Why do firefox try to write to it and why do it fail even with #13 workaround?

Why try firefox to access X lock?
Perhaps it is my misinterpretation of AppArmor, how can it be configured to restrict TCP or UDP traffic to/from specific ports?
The profile "abstractions/nameservice", under the section "# TCP/UDP network access", doesn't seem to lock the application to port 53. What am I missing? Restriction to specific ports is something that systrace can do so I'd expect nothing less from AppArmor.
I have quiet splash disabled so I can see what boot processes are run on startup, and I notice that on every time I boot my computer the Firefox profile is skipped. Here's the message: Code: Skipping profile in /etc/ apparmor.d/disable: usr.bin.firefox,I checked /etc/apparmor.d/disable, and see that there is indeed a link to usr.bin.firefox. So I'm wondering how/why it got there. I haven't touched anything in AppArmor since my clean install of Natty.
View 6 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 get the error message in the subject line, followed by a red failed message.
However, once the system is finished booting, I can log in and
Code:

and it starts normally.
But I couldn't find a modified version of it for Swiftfox anywhere, so I decided to modify it myself. But I'm not 100% sure that I did it correctly, so I thought I'd ask here.
Also, will Swiftfox 3.6.4 be able to use this same profile? I thought it might not because of the new "Out of process plugins" feature being added.
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?
