NAME chrome_selinux - Security Enhanced Linux Policy for the chrome pro- cesses

DESCRIPTION SELinux Linux secures chrome (policy for chrome) 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 ls

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

The following file types are defined for chrome:

chrome_sandbox_exec_t

- Set files with the chrome_sandbox_exec_t type, if you want to transi- tion an executable to the chrome_sandbox_t domain.

Paths: /opt/google/chrome/chrome-sandbox, /usr/lib(64)?/chromium- browser/chrome-sandbox

chrome_sandbox_nacl_exec_t

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

Paths: /opt/google/chrome/nacl_helper_bootstrap, /usr/lib/chromium- browser/nacl_helper_bootstrap

chrome_sandbox_tmp_t

- Set files with the chrome_sandbox_tmp_t type, if you want to store chrome sandbox temporary files in the /tmp directories.

chrome_sandbox_tmpfs_t

- Set files with the chrome_sandbox_tmpfs_t type, if you want to store chrome sandbox 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 ps

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

The following process types are defined for chrome:

chrome_sandbox_t, chrome_sandbox_nacl_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 pol- icy modules.

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