dccm_selinux(8) SELinux Policy documentation for dccm dccm_selinux(8)
NAME dccm_selinux - Security Enhanced Linux Policy for the dccm processes
DESCRIPTION Security-Enhanced Linux secures the dccm processes via flexible manda- tory access control.
The dccm processes execute with the dccm_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep dccm_t
ENTRYPOINTS The dccm_t SELinux type can be entered via the "dccm_exec_t" file type. The default entrypoint paths for the dccm_t domain are the following:"
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 dccm policy is very flexible allowing users to setup their dccm pro- cesses in as secure a method as possible.
The following process types are defined for dccm:
Note: semanage permissive -a dccm_t
can be used to make the process type dccm_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 dccm policy is very flexible allowing users to setup their dccm processes in as secure a method as possible.
The following file types are defined for dccm:
- Set files with the dccm_exec_t type, if you want to transition an executable to the dccm_t domain.
- Set files with the dccm_tmp_t type, if you want to store dccm tempo- rary files in the /tmp directories.
- Set files with the dccm_var_run_t type, if you want to store the dccm 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.
PORT TYPES SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux dccm policy is very flexible allowing users to setup their dccm processes in as secure a method as possible.
The following port types are defined for dccm:
Default Defined Ports: tcp 5679 udp 5679
MANAGED FILES The SELinux process type dccm_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.

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.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol- icy settings.
