ethereal_selinux(8)SELinux Policy documentation for ethereaethereal_selinux(8)

NAME ethereal_selinux - Security Enhanced Linux Policy for the ethereal pro- cesses

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

The ethereal processes execute with the ethereal_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 ethereal_t

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

/usr/sbin/ethereal.*

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

The following process types are defined for ethereal:

ethereal_t

Note: semanage permissive -a ethereal_t

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

The following file types are defined for ethereal:

ethereal_exec_t

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

ethereal_home_t

- Set files with the ethereal_home_t type, if you want to store ethe- real files in the users home directory.

ethereal_tmp_t

- Set files with the ethereal_tmp_t type, if you want to store ethereal temporary files in the /tmp directories.

ethereal_tmpfs_t

- Set files with the ethereal_tmpfs_t type, if you want to store ethe- real files on a tmpfs file system.

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 ethereal_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.

ethereal_home_t

/home/[^/]*/.ethereal(/.*)?

ethereal_tmp_t

ethereal_tmpfs_t

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

nfs_t

tmp_t

/tmp /usr/tmp /var/tmp /var/tmp/vi.recover

user_fonts_cache_t

/home/[^/]*/.fonts/auto(/.*)? /home/[^/]*/.fontconfig(/.*)? /home/[^/]*/.fonts.cache-.*

user_home_t

/home/[^/]*/.+

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.
