<h1 class="topictitle1">Plan physical workstation security</h1>
|
|
<div><p>This topic describes the security risks and recommendations for
|
|
workstations.</p>
|
|
<p>You might want all users to be able to sign on at any available workstation
|
|
and perform all authorized functions. However, if you have workstations that
|
|
are either very public or very private, you might want to ensure that unauthorized
|
|
users do not access functions on those workstations.</p>
|
|
<div class="p"><strong>Risks associated with workstations</strong><dl><dt class="dlterm">Using a workstation in a public location for unauthorized purposes</dt>
|
|
<dd>If people outside your company can easily access locations, they could
|
|
potentially see confidential information. If a system user leaves a workstation
|
|
signed on, someone from outside the company might be able to walk up and access
|
|
confidential information. </dd>
|
|
<dt class="dlterm">Using a workstation in a private location for unauthorized purposes</dt>
|
|
<dd>A workstation located in a private location gives an intruder the opportunity
|
|
to spend long hours trying to circumvent your security without being observed.</dd>
|
|
<dt class="dlterm">Using the playback function or a PC signon program on a display station
|
|
to circumvent security measures</dt>
|
|
<dd>Many display stations have a record and playback function, that allows
|
|
users to store frequently used keystrokes and repeat them by pressing a single
|
|
key. When you use a personal computer as a workstation on the system, you
|
|
can write a program to automate the signon process. Because users frequently
|
|
use the signon process , they might decide to store their user IDs and passwords,
|
|
rather than typing them every time they sign on.</dd>

|
<p><strong>What to do to keep your workstation secure</strong></p>
|
|
<p>You need to identify which workstations might pose a security risk. The
|
|
following information suggests ways to keep your workstation secure. Record
|
|
your choices on the Workstations and Printers section of the <a href="rzamvphysecplanworksheet.htm#physecplanworksheet">Physical
|
|
Security Planning worksheet</a>. Also see <a href="#planphystationsec__workstation_example">Example: Physical security planning form—workstations and printers</a>.</p>
|
|
<div class="p"><ul><li>Avoid placing workstations in very public or private locations.</li>
|
|
<li>Remind users that recording a password in a display station or in a PC
|
|
program violates system security.</li>
|
|
<li>Require users to sign off before leaving a workstation.</li>
|
|
<li>Take measures, such as using the inactive timer system values (WINACTITV
|
|
and QINACTMSCQ), to prevent users from leaving workstations in public locations
|
|
without signing off the system.</li>
|
|
<li>Restrict access to vulnerable workstations: <ul><li>Permit only user profiles with limited function.</li>
|
|
<li>Prevent people with security officer or service authority from signing
|
|
on at every workstation using the QLMTSECOFR system value.</li>
|
|
<li>Restrict users from signing on at more than one workstation at the same
|
|
time using the QLMTDEVSSN system value.</li>
|
|
</ul>
|
|
</li>
|
|
<li>Restrict *CHANGE authority to printers and other devices.</li>
|
|
</ul>
