-====== AppArmor - Create an AppArmor Profile ======
-===== Design a test plan =====
-Try to think about how the application should be exercised.  The test plan should be divided into small test cases.  Each test case should have a small description and list the steps to follow.
-Some standard test cases are:
-  * Starting the program.
-  * Stopping the program.
-  * Reloading the program.
-  * Testing all the commands supported by the init script.
-===== Generate the new profile =====
-Use **aa-genprof** to generate a new profile.
-<code bash>
-sudo aa-genprof executable
-</code>
-For example:
-<code bash>
-sudo aa-genprof slapd
-</code>
-To get your new profile included in the **apparmor-profiles** package, file a bug in Launchpad against the [[https://bugs.launchpad.net/ubuntu/+source/apparmor/+filebug|AppArmor]] package:
-  * Include your test plan and test cases.
-  * Attach your new profile to the bug.
-===== Profiles =====
-AppArmor profiles are simple text files located in **/etc/apparmor.d/**.  The files are named after the full path to the executable they profile replacing the "/" with ".".  For example /etc/apparmor.d/bin.ping is the AppArmor profile for the /bin/ping command.
-There are two main type of rules used in profiles:
-  * **Path entries**: which detail which files an application can access in the file system.
-  * **Capability entries**: determine what privileges a confined process is allowed to use.
-As an example take a look at /etc/apparmor.d/bin.ping:
-<file bash /etc/apparmor.d/bin.ping>
-#include <tunables/global>
-/bin/ping flags=(complain) {
-  #include <abstractions/base>
-  #include <abstractions/consoles>
-  #include <abstractions/nameservice>
-  capability net_raw,
-  capability setuid,
-  network inet raw,
-  /bin/ping mixr,
-  /etc/modules.conf r,
-}
-</file>
-  * #include <tunables/global>: include statements from other files. This allows statements pertaining to multiple applications to be placed in a common file.
-  * /bin/ping flags=(complain): path to the profiled program, also setting the mode to complain.
-  * capability net_raw,: allows the application access to the CAP_NET_RAW Posix.1e capability.
-  * /bin/ping mixr,: allows the application read and execute access to the file.
