comsat_selinux(8) SELinux Policy documentation for comsat comsat_selinux(8)
NAME comsat_selinux - Security Enhanced Linux Policy for the comsat pro- cesses
DESCRIPTION Security-Enhanced Linux secures the comsat processes via flexible mandatory access control.
The comsat processes execute with the comsat_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep comsat_t
ENTRYPOINTS The comsat_t SELinux type can be entered via the "comsat_exec_t" file type. The default entrypoint paths for the comsat_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 comsat policy is very flexible allowing users to setup their comsat processes in as secure a method as possible.
The following process types are defined for comsat:
Note: semanage permissive -a comsat_t
can be used to make the process type comsat_t permissive. Permissive process 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 comsat policy is very flexible allowing users to setup their comsat processes in as secure a method as possible.
The following file types are defined for comsat:
- Set files with the comsat_exec_t type, if you want to transition an executable to the comsat_t domain.
- Set files with the comsat_tmp_t type, if you want to store comsat temporary files in the /tmp directories.
- Set files with the comsat_var_run_t type, if you want to store the comsat 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 comsat policy is very flexible allowing users to setup their comsat processes in as secure a method as possible.
The following port types are defined for comsat:
Default Defined Ports: udp 512
MANAGED FILES The SELinux process type comsat_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.
/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev
/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.
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.
