chrome_selinux(8) chrome SELinux Policy documentation chrome_selinux(8)NAMEchrome_selinux - Security Enhanced Linux Policy for the chrome pro‐
cesses
DESCRIPTION
Security-Enhanced Linux secures the chrome processes via flexible
mandatory access control.
BOOLEANS
SELinux policy is customizable based on least access required. chrome
policy is extremely flexible and has several booleans that allow you to
manipulate the policy and run chrome with the tightest access possible.
If you want to allow unconfined users to transition to the chrome sand‐
box domains when running chrome-sandbo, you must turn on the uncon‐
fined_chrome_sandbox_transition boolean.
setsebool -P unconfined_chrome_sandbox_transition 1
NSSWITCH DOMAINFILE 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:
/usr/lib/chromium-browser/chrome-sandbox,
/opt/google/chrome/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 permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. 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.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
