apmd_selinux(8) SELinux Policy documentation for apmd apmd_selinux(8)
NAME apmd_selinux - Security Enhanced Linux Policy for the apmd processes
DESCRIPTION Security-Enhanced Linux secures the apmd processes via flexible manda- tory access control.
The apmd processes execute with the apmd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep apmd_t
ENTRYPOINTS The apmd_t SELinux type can be entered via the "mtrr_device_t,unla- beled_t,proc_type,apmd_exec_t,sysctl_type,filesystem_type,file_type" file types. The default entrypoint paths for the apmd_t domain are the following:"
/dev/cpu/mtrr, /usr/sbin/apmd, /usr/sbin/acpid, /usr/sbin/powersaved, all files on the system
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 apmd policy is very flexible allowing users to setup their apmd pro- cesses in as secure a method as possible.
The following process types are defined for apmd:
Note: semanage permissive -a apmd_t
can be used to make the process type apmd_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 apmd policy is very flexible allowing users to setup their apmd processes in as secure a method as possible.
The following file types are defined for apmd:
- Set files with the apmd_exec_t type, if you want to transition an executable to the apmd_t domain.
- 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
- 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.
- Set files with the apmd_tmp_t type, if you want to store apmd tempo- rary files in the /tmp directories.
- 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 apmd_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.
all files on the system
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.
