NAME

sandbox_selinux - Security Enhanced Linux Policy for the sandbox processes

DESCRIPTION

SELinux Linux secures sandbox (policy for sandbox) processes via flexible mandatory access control.

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

The following file types are defined for sandbox:

sandbox_devpts_t

- Set files with the sandbox_devpts_t type, if you want to treat the files as sandbox devpts data.

sandbox_exec_t

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

sandbox_file_t

- Set files with the sandbox_file_t type, if you want to treat the files as sandbox content.

sandbox_min_client_tmpfs_t

- Set files with the sandbox_min_client_tmpfs_t type, if you want to store sandbox min client files on a tmpfs file system.

sandbox_net_client_tmpfs_t

- Set files with the sandbox_net_client_tmpfs_t type, if you want to store sandbox net client files on a tmpfs file system.

sandbox_web_client_tmpfs_t

- Set files with the sandbox_web_client_tmpfs_t type, if you want to store sandbox web client files on a tmpfs file system.

sandbox_x_client_tmpfs_t

- Set files with the sandbox_x_client_tmpfs_t type, if you want to store sandbox x client files on a tmpfs file system.

sandbox_xserver_tmpfs_t

- Set files with the sandbox_xserver_tmpfs_t type, if you want to store sandbox xserver 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.

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

The following process types are defined for sandbox:

sandbox_x_client_t, sandbox_net_client_t, sandbox_xserver_t, sandbox_x_t, sandbox_web_client_t, sandbox_min_t, sandbox_net_t, sandbox_web_t, sandbox_min_client_t, sandbox_t

Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

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 policy modules.

system-config-selinux is a GUI tool available to customize SELinux policy settings.
