NAME cups_pdf_selinux - Security Enhanced Linux Policy for the cups_pdf pro- cesses

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

The cups_pdf processes execute with the cups_pdf_t SELinux type. You can check if you have these processes running by executing the ps com- mand with the -Z qualifier.

For example:

ps -eZ | grep cups_pdf_t

ENTRYPOINTS The cups_pdf_t SELinux type can be entered via the "cups_pdf_exec_t" file type. The default entrypoint paths for the cups_pdf_t domain are the following:"

/usr/lib/cups/backend/cups-pdf, /usr/lib64/cups/backend/cups-pdf

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 cups_pdf policy is very flexible allowing users to setup their cups_pdf processes in as secure a method as possible.

The following process types are defined for cups_pdf:

cups_pdf_t

Note: semanage permissive -a cups_pdf_t

can be used to make the process type cups_pdf_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 cups_pdf policy is very flexible allowing users to setup their cups_pdf processes in as secure a method as possible.

The following file types are defined for cups_pdf:

cups_pdf_exec_t

- Set files with the cups_pdf_exec_t type, if you want to transition an executable to the cups_pdf_t domain.

cups_pdf_tmp_t

- Set files with the cups_pdf_tmp_t type, if you want to store cups pdf temporary files in the /tmp directories.

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 cups_pdf_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.

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.
