<p style="margin-left:11%; margin-top: 1em">prewikka_script_selinux
− Security Enhanced Linux Policy for the
prewikka_script processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the prewikka_script processes via flexible
mandatory access control.</p>
<p style="margin-left:11%; margin-top: 1em">The
prewikka_script processes execute with the prewikka_script_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 prewikka_script_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
prewikka_script_t SELinux type can be entered via the
<b>prewikka_script_exec_t, shell_exec_t,
prewikka_script_exec_t</b> file types.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the prewikka_script_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/share/prewikka/cgi-bin(/.*)?,
/bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash,

<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
prewikka_script policy is very flexible allowing users to
setup their prewikka_script processes in as secure a method
as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for prewikka_script:</p>
<p style="margin-left:11%; margin-top: 1em"><b>prewikka_script_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a prewikka_script_t</b> can be used
to make the process type prewikka_script_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.
prewikka_script policy is extremely flexible and has several
booleans that allow you to manipulate the policy and run
prewikka_script with the tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow users to resolve user passwd entries directly from
ldap rather then using a sssd server, you must turn on the
authlogin_nsswitch_use_ldap boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
authlogin_nsswitch_use_ldap 1</b></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"><b>setsebool -P
deny_ptrace 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow any process to mmap any file on system with attribute
file_type, you must turn on the domain_can_mmap_files
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
allow all domains to use other domains file descriptors, you
must turn on the domain_fd_use boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_fd_use 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to

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

<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

<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
global_ssp 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow httpd cgi support, you must turn on the
httpd_enable_cgi boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
httpd_enable_cgi 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow confined applications to run with kerberos, you must
turn on the kerberos_enabled boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
kerberos_enabled 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P

must turn on the nscd_use_shm boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nscd_use_shm 1</b></p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type prewikka_script_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.</p>
<p style="margin-left:11%; margin-top: 1em"><b>prewikka_rw_content_t</b></p>
<h2>FILE CONTEXTS
<a name="FILE CONTEXTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux
requires files to have an extended attribute to define the
file type.</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a file using the <b>−Z</b> option to
<b>ls</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to these files. SELinux
prewikka_script policy is very flexible allowing users to
setup their prewikka_script processes in as secure a method
as possible.</p>
<p style="margin-left:11%; margin-top: 1em"><i>The
following file types are defined for
prewikka_script:</i></p>
<p style="margin-left:11%; margin-top: 1em"><b>prewikka_script_exec_t</b></p>
<p style="margin-left:11%; margin-top: 1em">- Set files
with the prewikka_script_exec_t type, if you want to
transition an executable to the prewikka_script_t
domain.</p>
<p style="margin-left:11%; margin-top: 1em">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</b> command. This will
modify the SELinux labeling database. You will need to use
<b>restorecon</b> to apply the labels.</p>
<h2>COMMANDS
<a name="COMMANDS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
fcontext</b> can also be used to manipulate default file
context mappings.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
permissive</b> can also be used to manipulate whether or not
a process type is permissive.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
module</b> can also be used to enable/disable/install/remove
policy modules.</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
boolean</b> can also be used to manipulate the booleans</p>
<p style="margin-left:11%; margin-top: 1em"><b>system-config-selinux</b>
is a GUI tool available to customize SELinux policy
settings.</p>
