<h1 class="topictitle1">SSL for secure Telnet access</h1>
|
|
<div><p>You can configure your Telnet server to use the Secure Sockets
|
|
Layer (SSL) to secure Telnet communications sessions. </p>
|
|
<p><img src="./delta.gif" alt="Start of change" />To configure your Telnet server to use SSL, you must use Digital
|
|
Certificate Manager (DCM) to configure the certificate for the
|
|
Telnet server to use. By default the Telnet server handles both secure and
|
|
non-secure connections. However, you can configure Telnet so that it allows
|
|
only secure Telnet sessions. Additionally, you can configure the Telnet server
|
|
to use digital certificates for stronger client authentication.<img src="./deltaend.gif" alt="End of change" /></p>
|
|
<p><img src="./delta.gif" alt="Start of change" />When you choose to use SSL with Telnet, you gain some strong
|
|
security benefits. For Telnet, besides server authentication, the data is
|
|
encrypted before any Telnet protocol data flows. Once the SSL session is established,
|
|
all Telnet protocols including user ID and password exchange, are encrypted.<img src="./deltaend.gif" alt="End of change" /></p>
|
|
<p>The most important factor to consider when using the Telnet server is the
|
|
sensitivity of the information that you use in a client session. If the information
|
|
is sensitive or private, then you may find it beneficial to set up your iSeries™ Telnet
|
|
server using SSL. When you configure a digital certificate for the Telnet
|
|
application, the Telnet server is able to operate with both SSL and non-SSL
|
|
clients. If your security policy requires that you always encrypt your Telnet
|
|
sessions, you can disable all non-SSL Telnet sessions. When there is no need
|
|
for you to use the SSL Telnet server, you can turn off the SSL port. You can
|
|
disable the ports using the ADDTCPPORT command. Once you have turned off the
|
|
port, the server provides non-SSL Telnet for the clients, and the SSL Telnet
|
|
sessions are disabled.</p>
