<div><p> You might need to know how to set up your anonymous File Transfer
|
||
|
|
Protocol (FTP) and ensure the security of your FTP.</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Skill requirements</h4><p>To set up anonymous FTP, you
|
||
|
|
need the following skills:</p>
|
||
|
|
<ul><li>Familiarity with the iSeries™ character-based interface and commands with
|
||
|
|
multiple parameters and keywords.</li>
|
||
|
|
<li>Ability to create libraries, members, and source physical files on your iSeries (you
|
||
|
|
should have at least *SECOFR authority).</li>
|
||
|
|
<li>Ability to assign authorities to libraries, files, members, and programs.</li>
|
||
|
|
<li>Ability to write, change, compile, and test programs on your iSeries server.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Security considerations</h4><p>The first step in implementing
|
||
|
|
anonymous FTP is to define your anonymous FTP server site policy. This plan
|
||
|
|
defines the FTP site security and determines how to code your exit programs.
|
||
|
|
Because the FTP server will allow anyone to access your data, you must carefully
|
||
|
|
consider how you want it to be used, and what data must be protected.</p>
|
||
|
|
<p>Review the following guidelines for your FTP site policy plan:</p>
|
||
|
|
<ul><li>Use a firewall between your iSeries server and the Internet.</li>
|
||
|
|
<li>Use a non-production iSeries for your FTP server.</li>
|
||
|
|
<li>Do not attach the FTP server to the rest of your company's LANs or WANs.</li>
|
||
|
|
<li>Use FTP exit programs to secure access to the FTP server.</li>
|
||
|
|
<li>Test FTP exit programs to ensure that they do not contain security loopholes.</li>
|
||
|
|
<li>Do not allow anonymous FTP users to have read and write access to the
|
||
|
|
same directory. This permits the anonymous user to be untraceable on the Internet.</li>
|
||
|
|
<li>Allow ANONYMOUS access only. Do not allow any other userids and do not
|
||
|
|
authenticate passwords.</li>
|
||
|
|
<li>Restrict ANONYMOUS access to one public library or directory only. (Where
|
||
|
|
will it be? What will you call it?)</li>
|
||
|
|
<li>Place only public access files in the public library or directory.</li>
|
||
|
|
<li>Restrict ANONYMOUS users to 'view' and 'retrieve' subcommands only (get,
|
||
|
|
mget). <span class="uicontrol">Do not under any circumstances allow ANONYMOUS users to
|
||
|
|
use CL commands.</span></li>
|
||
|
|
<li>Log all access to your iSeries FTP server.</li>
|
||
|
|
<li>Review FTP server logs daily or weekly for possible attacks.</li>
|
||
|
|
<li>Verify that the FTP server registers the correct exit programs once a
|
||
|
|
month.</li>
|
||
|
|
<li>Test the FTP server for security holes once a month.</li>
