<p style="margin-left:11%; margin-top: 1em">antivirus_selinux
− Security Enhanced Linux Policy for the antivirus
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the antivirus processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The antivirus
processes execute with the antivirus_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 antivirus_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The antivirus_t
SELinux type can be entered via the <b>antivirus_exec_t</b>
file type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the antivirus_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/amavisd.*,
/usr/sbin/amavi, /usr/sbin/clamd, /usr/bin/clamscan,
/usr/bin/clamdscan, /usr/bin/freshclam,
/usr/sbin/clamav-milter, /usr/lib/AntiVir/antivir</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
antivirus policy is very flexible allowing users to setup
their antivirus processes in as secure a method as
possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for antivirus:</p>
<p style="margin-left:11%; margin-top: 1em"><b>antivirus_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a antivirus_t</b> can be used to
make the process type antivirus_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. antivirus
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run antivirus with
the tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether antivirus programs can use JIT compiler,
you must turn on the antivirus_use_jit boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
antivirus_use_jit 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
dontaudit all daemons scheduling requests (setsched,
sys_nice), you must turn on the daemons_dontaudit_scheduling
boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
daemons_dontaudit_scheduling 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
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
nis_enabled 1</b></p>
<h2>NSSWITCH DOMAIN
<a name="NSSWITCH DOMAIN"></a>
</h2>
<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 for the antivirus_t,
you must turn on the authlogin_nsswitch_use_ldap
boolean.</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
allow confined applications to run with kerberos for the
antivirus_t, you must turn on the kerberos_enabled
boolean.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
kerberos_enabled 1</b></p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type antivirus_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>
