apm_selinux(8) SELinux Policy documentation for apm apm_selinux(8)

NAME apm_selinux - Security Enhanced Linux Policy for the apm processes

DESCRIPTION Security-Enhanced Linux secures the apm processes via flexible manda- tory access control.

The apm processes execute with the apm_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep apm_t

ENTRYPOINTS The apm_t SELinux type can be entered via the "apm_exec_t" file type. The default entrypoint paths for the apm_t domain are the following:"

/usr/bin/apm

PROCESS TYPES SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to ps

Policy governs the access confined processes have to files. SELinux apm policy is very flexible allowing users to setup their apm processes in as secure a method as possible.

The following process types are defined for apm:

apm_t, apmd_t

Note: semanage permissive -a apm_t

can be used to make the process type apm_t permissive. Permissive pro- cess types are not denied access by SELinux. AVC messages will still be generated.

FILE CONTEXTS SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls

Policy governs the access confined processes have to these files. SELinux apm policy is very flexible allowing users to setup their apm processes in as secure a method as possible.

The following file types are defined for apm:

apm_exec_t

- Set files with the apm_exec_t type, if you want to transition an exe- cutable to the apm_t domain.

apmd_exec_t

- Set files with the apmd_exec_t type, if you want to transition an executable to the apmd_t domain.

apmd_lock_t

- Set files with the apmd_lock_t type, if you want to treat the files as apmd lock data, stored under the /var/lock directory

apmd_log_t

- Set files with the apmd_log_t type, if you want to treat the data as apmd log data, usually stored under the /var/log directory.

apmd_tmp_t

- Set files with the apmd_tmp_t type, if you want to store apmd tempo- rary files in the /tmp directories.

apmd_var_run_t

- Set files with the apmd_var_run_t type, if you want to store the apmd files under the /run directory.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.

MANAGED FILES The SELinux process type apm_t can manage files labeled with the fol- lowing file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

tmp_t

/tmp /usr/tmp /var/tmp /var/tmp/vi.recover

COMMANDS semanage fcontext can also be used to manipulate default file context mappings.

semanage permissive can also be used to manipulate whether or not a process type is permissive.

semanage module can also be used to enable/disable/install/remove pol- icy modules.

system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
