NAME

sandbox_min_client_selinux - Security Enhanced Linux Policy for the sandbox_min_client processes

DESCRIPTION

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

The sandbox_min_client processes execute with the sandbox_min_client_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep sandbox_min_client_t

ENTRYPOINTS

The sandbox_min_client_t SELinux type can be entered via the sandbox_exec_t file type.

The default entrypoint paths for the sandbox_min_client_t domain are the following:

/usr/share/sandbox/start

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

The following process types are defined for sandbox_min_client:

sandbox_min_client_t

Note: semanage permissive -a sandbox_min_client_t can be used to make the process type sandbox_min_client_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

SELinux policy is customizable based on least access required. sandbox_min_client policy is extremely flexible and has several booleans that allow you to manipulate the policy and run sandbox_min_client with the tightest access possible.

If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Disabled by default.

setsebool -P deny_execmem 1

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

MANAGED FILES

The SELinux process type sandbox_min_client_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.

cifs_t

fusefs_t

/run/user/[0-9]+/gvfs

mozilla_plugin_tmpfs_t

nfs_t

sandbox_file_t

sandbox_min_client_tmpfs_t

security_t

/selinux

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.

semanage boolean can also be used to manipulate the booleans

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