<h1 class="title">Security in Fuseki2</h1>
<p>Fuseki2 webapp provides security by using <a href="http://shiro.apache.org/">Apache Shiro</a>.
This is controlled by the configuration file <code>shiro.ini</code> located at
<code>$FUSEKI_BASE/shiro.ini</code>. If not found, the server initializes with a default
configuration. This can then be replaced or edited as required. An existing file
is never overwritten by the server.</p>
<p>In its default configuration, SPARQL endpoints are open to the public but
administrative functions are limited to <code>localhost</code>. One can access it via
<code>http://localhost:.../...</code>. Or the according IPv4 or IPv6 address, for example
<code>127.0.0.1</code> (IPv4), or <code>[::1]</code> (IPv6). Access from an external machine is not
considered as localhost and thus restricted.</p>
<p>Once Shiro has been configured to perform user authentication it provides a
good foundation on which the <a href="../permissions/">Jena Permissions</a> layer can be
configured. There is an <a href="../permissions/example.html">example implementation</a>
documented in the Jena Permissions section. The Jena Permissions layer can be
used to restrict access to specific graphs or triples within graphs.</p>
<p>A simple example to enable basic user/password authentication is shown in the
default <code>shiro.ini</code> configuration. The default admin user is <code>admin</code> and the
password is <code>pw</code>. This can be changed directly in the INI file. Note that this
setup is not recommended for production for various reasons (no TLS, passwords
in plain text etc.), consult the <a href="https://shiro.apache.org/configuration.html#Configuration-INISections">Shiro
INI</a>
documentation for best practices.</p>
<p>As mentioned above, the default setup only restricts access to the admin pages
of Fuseki. To avoid clashes with dataset names, the namespace of the admin
interface starts with &lsquo;/$/', consult the <a href="../fuseki2/fuseki-server-protocol.html">Fuseki HTTP Administration Protocol
</a> documentation for more details.</p>
<p>If access to SPARQL endpoints should be restricted, additional <a href="https://shiro.apache.org/web.html#Web-WebINIconfiguration">Shiro
ACLs</a> are necessary.
This is done in the <code>[urls]</code> section of the configuration. As an example,
restricting access to the <code>../query</code> SPARQL endpoint for all datasets on Fuseki
could be done with this wildcard pattern:</p>
<p><code>/**/query = authcBasic,user[admin]</code></p>
<p>Anonymous SPARQL queries would no longer be possible in this example.</p>
<p>Again, please consult the <a href="https://shiro.apache.org/">Apache Shiro</a> website for
details and more sophisticated setups. The default configuration of Fuseki is
kept simple but is <em>not</em> recommended for setups where sensitive data is
provided.</p>
<p>Changing the security setup requires a server restart.</p>
<p>Contributions of more examples are very welcome.</p>
<h2 id="examples">Examples</h2>
<p>The shipped <code>shiro.ini</code> has additional comments.</p>
<h3 id="the-default-configuration">The default configuration.</h3>
<p>This is a minimal configuration for the default configuration.</p>
<pre><code>[main]
localhost=org.apache.jena.fuseki.authz.LocalhostFilter
[urls]
## Control functions open to anyone
/$/server = anon
/$/ping = anon
## and the rest are restricted to localhost.
## See above for 'localhost'
/$/** = localhost
/**=anon
</code></pre>
<h3 id="simple-userpassword">Simple user/password</h3>
<p>This extract shows the simple user/password setup.</p>
<p>It adds a <code>[users]</code> section and changes the <code>/$/**</code> line in <code>[urls]</code></p>
<pre><code>[users]
admin=pw
[urls]
## Control functions open to anyone
/$/status = anon
/$/ping = anon
/$/** = authcBasic,user[admin]
# Everything else
/**=anon
</code></pre>
