Security Hardening

<h2>Changing the default web server port</h2>

<p>If you would like to change the default port used for web traffic you can edit the ><span<span class="keyword">WWWServerPort</span> Registry key.</p>

<table class="confluenceTable">
    <tbody>
        <tr>
            <th class="confluenceTh" width=216>Registry String data value</th>
            <th class="confluenceTh">Description</th>
        </tr>
        <tr>
            <td class="confluenceTd"><span class="keyword">WWWServerPort  = port number</span></td>
            <td class="confluenceTd">Port address for webserver to listen on (Default is 80, unless changed during setup)</td>
        </tr>
    </tbody>
</table>

<h2>Enabling High Security mode</h2>

<p>To enable High Security mode, add the following Registry String value:-</p>

<div class="panelMacro"><table class="noteMacro"><colgroup><col width="24"><col></colgroup><tbody><tr><td valign="top"><img width="16" height="16" border="0" align="absmiddle" alt="" src="/images/icons/emoticons/warning.png"></td><td><p><strong>NOTE:</strong> <strong>The value of <span class="keyword">PasswordComplexity</span> must always be 8 characters, otherwise the policy will not be implemented.</strong> The order of each Type pair (Type character and amount character) is not important.</p></td></tr></tbody></table></div>

<h2>Automatic expiry of Web user passwords</h2>

<p>You can force Web users to change the password after a predetermined age has been set. Note that this is a system wide setting.</p>

<p>The server running TIM Enterprise will email the web user advising 
that a password change is required. The web user must have an email 
address configured for notification to take place.</p>

<p>If the password is not changed by the expiry date then the account is automatically disabled.</p>

<table class="confluenceTable">
	<tbody>
		<tr>
			<th class="confluenceTh" width=166>Registry String data value</th>
			<th class="confluenceTh">Description</th>
		</tr>
  		<tr>
    		<td class="confluenceTd"><span class="keyword">PasswordExpiryTimeUnits</span></td>
    		<td class="confluenceTd">Determines the time units that the related expiry entries (below) will use.&nbsp; Valid values are "minutes", "hours", "days", "weekdays"</td>
  		</tr>
  		<tr>
    		<td class="confluenceTd"><span class="keyword">PasswordExpiryReminder</span></td>
    		<td class="confluenceTd">A value, in the units described by the ><span<span class="keyword">PasswordExpiryTimeUnits</span> entry, after which an email is sent to the web user to remind them to change their password.</td>
  		</tr>
 		 <tr>
    		<td class="confluenceTd"><span class="keyword">PasswordExpiryDisable</span></td>
    		<td class="confluenceTd">A value, in the units described by the ><span<span class="keyword">PasswordExpiryTimeUnits</span> entry, which specifies how long after the reminder email (above) is sent, that a web user's account will be disabled if it hasn't been updated.</td>
  		</tr>
	</tbody>
</table>

<p>Default values for the above settings are as follows:-</p>

<ul>
  <li><span class="keyword">PasswordExpiryTimeUnits</span> = "days"</li>
  <li><span class="keyword">PasswordExpiryReminder</span> = "7"</li>
  <li><span class="keyword">PasswordExpiryDisable</span> = "7"</li> 
</ul>

<p>Therefore, using the default settings, a web user will receive an 
email reminder after 7 days. The account will be disabled after 14 days 
(7 plus 7).</p>

<p>If the ><span<span class="keyword">PasswordExpiryReminder</span> value is zero then password 
reminder functionality is disabled and neither a reminder email will be 
sent, nor will a web user's account be disabled. Since this value has a 
default of "7", this value must be explicitly set to zero to disable 
password reminder functionality.</p>

<p>If the ><span<span class="keyword">PasswordExpiryDisable</span> value is explicitly set to zero, the disabling of a web user's account is skipped.</p>
