<h1 class="topictitle1">Risk: Access to system directories through mapped drives</h1>
|
|||
|
|
<div><p>This topic describes security risks to system directories and provides
|
|||
|
|
recommendations for reducing these risks.</p>
|
|||
|
|
<p>Assume that a PC is connected to your server with an IBM<sup>®</sup> iSeries™ Access
|
|||
|
|
for Windows<sup>®</sup> session.
|
|||
|
|
The session set up mapped drives to link to the system's integrated file system.
|
|||
|
|
For example, the PC’s <span class="filepath">G</span> drive might map to the integrated
|
|||
|
|
file system of the SYSTEM1 server in the network.</p>
|
|||
|
|
<p>Now assume that the same PC user has a browser and can access the Internet.
|
|||
|
|
The user requests a Web page that runs a mischievous <span class="q">"program"</span> such as
|
|||
|
|
a Java™ applet
|
|||
|
|
or an Active-X control. Conceivably, the program could attempt to erase everything
|
|||
|
|
on the PC’s <span class="filepath">G</span> drive.</p>
|
|||
|
|
<div class="p">You have several protections against damage to mapped drives:<ul><li>Your most important protection is resource security on your server. The Java applet
|
|||
|
|
or Active-X control looks to the server like the user who established the
|
|||
|
|
PC session. You need to carefully manage what each PC user is authorized
|
|||
|
|
to do on your server.</li>
|
|||
|
|
<li>Advise your PC users to set their browsers to prevent attempts to access
|
|||
|
|
mapped drives. This works for Java applets but not for Active-X controls.</li>
|
|||
|
|
<li>Educate your users about the dangers of being connected to your server
|
|||
|
|
and the Internet in the same session. Also, make sure your PC users understand
|
|||
|
|
that drives remain mapped even when the iSeries Access session appears to be
|
|||
|
|
ended.</li>
|
|||
|
