<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">sftpd_selinux
− Security Enhanced Linux Policy for the sftpd
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the sftpd processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The sftpd
processes execute with the sftpd_t SELinux type. You can
check if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |
grep sftpd_t</b></p>
<h2>PROCESS TYPES
<a name="PROCESS TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
process types (domains) for each process running on the
system</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a process using the <b>−Z</b> option to
<b>ps</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to files. SELinux sftpd
policy is very flexible allowing users to setup their sftpd
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for sftpd:</p>
<p style="margin-left:11%; margin-top: 1em"><b>sftpd_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a sftpd_t</b> can be used to make
the process type sftpd_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux
denials) messages are still generated.</p>
<h2>BOOLEANS
<a name="BOOLEANS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. sftpd policy
is extremely flexible and has several booleans that allow
you to manipulate the policy and run sftpd with the tightest
access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled
by default.</p>

<p style="margin-left:11%; margin-top: 1em">If you want to

boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_can_mmap_files 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains write to kmsg_device, while kernel is
executed with systemd.log_target=kmsg parameter, you must
turn on the domain_can_write_kmsg boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_can_write_kmsg 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to

domain_fd_use 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to

turn on the domain_kernel_load_modules boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_kernel_load_modules 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to execute in fips_mode, you must turn on
the fips_mode boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
fips_mode 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
enable reading of urandom for all domains, you must turn on
the global_ssp boolean. Disabled by default.</p>

<p style="margin-left:11%; margin-top: 1em">If you want to
