Security Enhanced Linux Policy for the sysadm_dbusd processes


Security-Enhanced Linux secures the sysadm_dbusd processes via flexible mandatory access control.

The sysadm_dbusd processes execute with the sysadm_dbusd_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 sysadm_dbusd_t


The sysadm_dbusd_t SELinux type can be entered via the dbusd_exec_t file type.

The default entrypoint paths for the sysadm_dbusd_t domain are the following:

/usr/bin/dbus-daemon(-1)?, /bin/dbus-daemon, /usr/bin/dbus-broker, /usr/bin/dbus-broker-launch, /lib/dbus-1/dbus-daemon-launch-helper, /usr/lib/dbus-1/dbus-daemon-launch-helper, /usr/libexec/dbus-1/dbus-daemon-launch-helper

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 psbP

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

The following process types are defined for sysadm_dbusd:


Note: semanage permissive -a sysadm_dbusd_t can be used to make the process type sysadm_dbusd_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.  sysadm_dbusd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sysadm_dbusd 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

Managed Files

The SELinux process type sysadm_dbusd_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.
















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.
