.SH "NAME"
efsutils_selinux \- Security Enhanced Linux Policy for the efs-utils processes
.SH "DESCRIPTION"

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

The efs-utils processes execute with the efsutils_t SELinux type. You can check if you have these processes running by executing the \fBps\fP command with the \fB\-Z\fP qualifier.

For example:

.B ps -eZ | grep efsutils_t


.SH "ENTRYPOINTS"

The efsutils_t SELinux type can be entered via the \fBefsutils_exec_t\fP file type.

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

/usr/bin/amazon-efs-mount-watchdog
.SH PROCESS TYPES
SELinux defines process types (domains) for each process running on the system
.PP
You can see the context of a process using the \fB\-Z\fP option to \fBps\bP
.PP
Policy governs the access confined processes have to files.
SELinux efs-utils policy is very flexible allowing users to setup their efs-utils processes in as secure a method as possible.
.PP
The following process types are defined for efs-utils:

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

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


.PP
If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

.EX
.B setsebool -P daemons_dontaudit_scheduling 1

.EE

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

.EX
.B setsebool -P fips_mode 1

.EE

.SH "MANAGED FILES"

The SELinux process type efsutils_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.

.SH FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.
.PP
You can see the context of a file using the \fB\-Z\fP option to \fBls\bP
.PP
Policy governs the access confined processes have to these files.
SELinux efs-utils policy is very flexible allowing users to setup their efs-utils processes in as secure a method as possible.
.PP

.PP
.B STANDARD FILE CONTEXT

SELinux defines the file context types for the efs-utils, if you wanted to
store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

.B semanage fcontext -a -t efsutils_exec_t '/srv/efs-utils/content(/.*)?'
.br
.B restorecon -R -v /srv/myefs-utils_content

Note: SELinux often uses regular expressions to specify labels that match multiple files.

.I The following file types are defined for efs-utils:


.EX
.PP
.B efsutils_exec_t
.EE

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


.EX
.PP
.B efsutils_log_t
.EE

- Set files with the efsutils_log_t type, if you want to treat the data as efs-utils log data, usually stored under the /var/log directory.


.EX
.PP
.B efsutils_unit_file_t
.EE

- Set files with the efsutils_unit_file_t type, if you want to treat the files as efs-utils unit content.


.PP
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
.B semanage fcontext
command.  This will modify the SELinux labeling database.  You will need to use
.B restorecon
to apply the labels.

.SH "COMMANDS"
.B semanage fcontext
can also be used to manipulate default file context mappings.
.PP
.B semanage permissive
can also be used to manipulate whether or not a process type is permissive.
.PP
.B semanage module
can also be used to enable/disable/install/remove policy modules.

.B semanage boolean
can also be used to manipulate the booleans

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