NAME

aa-status - display various information about the current AppArmor policy.

SYNOPSIS

aa-status [option]

DESCRIPTION

aa-status will report various aspects of the current state of AppArmor confinement. By default, it displays the same information as if the --verbose argument were given. A sample of what this looks like is:

  apparmor module is loaded.
  110 profiles are loaded.
  102 profiles are in enforce mode.
  8 profiles are in complain mode.
  Out of 129 processes running:
  13 processes have profiles defined.
  8 processes have profiles in enforce mode.
  5 processes have profiles in complain mode.

Other argument options are provided to report individual aspects, to support being used in scripts.

OPTIONS

aa-status accepts only one argument at a time out of:

--enabled: returns error code if AppArmor is not enabled.
--profiled: displays the number of loaded AppArmor policies.
--enforced: displays the number of loaded enforcing AppArmor policies.
--complaining: displays the number of loaded non-enforcing AppArmor policies.
--kill: displays the number of loaded enforcing AppArmor policies that will kill tasks on policy violations.
--prompt: displays the number of loaded enforcing AppArmor policies, with fallback to userspace mediation.
--special-unconfined: displays the number of loaded non-enforcing AppArmor policies that are in the special unconfined mode.
--process-mixed displays the number of processes confined by profile stacks with profiles in different modes.
--verbose: displays multiple data points about loaded AppArmor policy set (the default action if no arguments are given).
--json: displays multiple data points about loaded AppArmor policy set in a JSON format, fit for machine consumption.
--pretty-json: same as --json, formatted to be readable by humans as well as by machines.
--show: what data sets to show information about. Currently processes, profiles, all for both processes and profiles. The default is all.
--count: display only counts for selected information.
--filter.mode=filter: Allows specifying a posix regular expression filter that will be applied against the displayed processess and profiles apparmor profile mode, reducing the output.
--filter.profiles=filter: Allows specifying a posix regular expression filter that will be applied against the displayed processess and profiles confining profile, reducing the output.
--filter.pid=filter: Allows specifying a posix regular expression filter that will be applied against the displayed processes, so that only processes pids matching the expression will be displayed.
--filter.exe=filter: Allows specifying a posix regular expression filter that will be applied against the displayed processes, so that only processes executable name matching the expression will be displayed.
--help: displays a short usage statement.

EXIT STATUS

Upon exiting, aa-status will set its exit status to the following values:

0: if apparmor is enabled and policy is loaded.
1: if apparmor is not enabled/loaded.
2: if apparmor is enabled but no policy is loaded.
3: if the apparmor control files aren't available under /sys/kernel/security/.
4: if the user running the script doesn't have enough privileges to read the apparmor control files.
42: if an internal error occurred.

BUGS

aa-status must be run as root to read the state of the loaded policy from the apparmor module. It uses the /proc filesystem to determine which processes are confined and so is susceptible to race conditions.
