XK0-006 Practice Question: A server running Ubuntu 22.04 has AppArmor enabled
A server running Ubuntu 22.04 has AppArmor enabled. After installing a new application, the application is denied access to certain files even though the permissions are correct. The administrator checks the AppArmor profile and finds it is in enforce mode. Which command can be used to temporarily set the profile to complain mode to generate log entries for needed accesses?
⚠ Common exam trap
A common mix-up: candidates confuse `aa-complain` with `aa-enforce` or think that restarting the AppArmor service or reloading the profile will change the mode, when in fact only `aa-complain` or `aa-enforce` directly alter the profile's operational mode.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
aa-complain /usr/bin/application
`aa-complain /usr/bin/application`, is correct because it sets the specified AppArmor profile to complain mode, which logs policy violations without blocking access. This allows the administrator to identify which accesses the application needs by reviewing the generated log entries, typically in `/var/log/syslog` or via `ausearch`, while the application continues to run.
