## Enabled profiles
|
|
|
|
Once installed and with the rules enabled, you can ensure the rules are loaded
|
|
with:
|
|
```sh
|
|
sudo aa-status
|
|
```
|
|
|
|
It should give something like:
|
|
```
|
|
apparmor module is loaded.
|
|
1441 profiles are loaded.
|
|
112 profiles are in enforce mode.
|
|
...
|
|
0 profiles are in kill mode.
|
|
0 profiles are in unconfined mode.
|
|
155 processes have profiles defined.
|
|
14 processes are in enforce mode.
|
|
...
|
|
141 processes are in complain mode.
|
|
...
|
|
0 processes are unconfined but have a profile defined.
|
|
0 processes are in mixed mode.
|
|
0 processes are in kill mode.
|
|
```
|
|
|
|
You can also list the current processes alongside with their security profile with:
|
|
```sh
|
|
ps auxZ
|
|
```
|
|
|
|
Most of the processes should then be confined:
|
|
```
|
|
unconfined root /usr/lib/systemd/systemd --switched-root --system --deserialize 33
|
|
systemd-udevd (complain) root /usr/lib/systemd/systemd-udevd
|
|

|
|
rngd (complain) root /usr/bin/rngd -f

|
|

|
|

|
|
unconfined user (sd-pam)
|
|
gdm-wayland-session (complain) user /usr/lib/gdm-wayland-session /usr/bin/gnome-session
|
|

|
|
gnome-session-ctl (complain) user /usr/lib/gnome-session-ctl --monitor
|
|

|
|
```
|
|
|
|
??? info "Hide the kernel thread in `ps`"
|
|
|
|
To hide the kernel thread in `ps` use `ps auxZ | grep -v '\[.*\]'`. You can
|
|
add an alias in your shell:
|
|
```sh
|
|
alias p="ps auxZ | grep -v '\[.*\]'"
|
|
```
|
|
|

## AppArmor Log
|
|
|
|
Ensure that `auditd` is installed and running on your system in order to read
|
|
AppArmor log from `/var/log/audit/audit.log`. Then you can see the log with the
|
|
provided command `aa-log` allowing you to review AppArmor generated messages in
|
|
a colorful way.
|
|
|
|
Other AppArmor userspace tools such as `aa-enforce`, `aa-complain`, and `aa-logprof`
|
|
should work as expected.
|
|
|
|
|
|
### Basic use
|
|
|
|
To read the AppArmor log from `/var/log/audit/audit.log`:
|
|
```sh
|
|
aa-log
|
|
```
|
|
|
|
To optionally filter a given profile name: `aa-log <profile-name>` (your shell will autocomplete the profile name):
|
|
```
|
|
aa-log dnsmasq
|
|
DENIED dnsmasq open /proc/sys/kernel/osrelease comm=dnsmasq requested_mask=r denied_mask=r
|
|
DENIED dnsmasq open /proc/1/environ comm=dnsmasq requested_mask=r denied_mask=r
|
|
DENIED dnsmasq open /proc/cmdline comm=dnsmasq requested_mask=r denied_mask=r
|
|
```
|
|
|
|
!!! info
|
|
|
|
Other logs file in `/var/log/audit/` can easily be checked: `aa-log -f 1`
|
|
parses `/var/log/audit/audit.log.1`.
|
|
|
|
|
|
### Help
|
|
|
|
```
|
|
aa-log [-h] [--systemd] [--file file] [profile]
|
|
|
|
Review AppArmor generated messages in a colorful way. Supports logs from
|
|
auditd, systemd, syslog as well as dbus session events.
|
|
|
|
It can be given an optional profile name to filter the output with.
|
|
|
|
Default logs are read from '/var/log/audit/audit.log'. Other files in
|
|
'/var/log/audit/' can easily be checked: 'aa-log -f 1' parses 'audit.log.1'
|
|
|
|
Options:
|
|
-h, --help Show this help message and exit.
|
|
-f, --file FILE Set a logfile or a suffix to the default log file.
|
|
-s, --systemd Parse systemd logs from journalctl.
|
|
```
