Security-Enhanced Linux secures the systemd_sleep processes via flexible mandatory access control.
The systemd_sleep processes execute with the systemd_sleep_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep systemd_sleep_t
The systemd_sleep_t SELinux type can be entered via the systemd_sleep_exec_t file type.
The default entrypoint paths for the systemd_sleep_t domain are the following:
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 psbP
Policy governs the access confined processes have to files. SELinux systemd_sleep policy is very flexible allowing users to setup their systemd_sleep processes in as secure a method as possible.
The following process types are defined for systemd_sleep:
Note: semanage permissive -a systemd_sleep_t can be used to make the process type systemd_sleep_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. systemd_sleep policy is extremely flexible and has several booleans that allow you to manipulate the policy and run systemd_sleep with the tightest access possible.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
The SELinux process type systemd_sleep_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
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 lsbP
Policy governs the access confined processes have to these files. SELinux systemd_sleep policy is very flexible allowing users to setup their systemd_sleep processes in as secure a method as possible.
The following file types are defined for systemd_sleep:
- Set files with the systemd_sleep_exec_t type, if you want to transition an executable to the systemd_sleep_t domain.
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.
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 policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
