<h2 id="rzahjsec">APPC, APPN, and HPR security</h2>
|
||
|
|
<p>The following are some aspects of security for iSeries systems communicating
|
||
|
|
with each other using APPC, APPN, and HPR: </p>
|
||
|
|
<ul>
|
||
|
|
<li><span class="bold">General security considerations:</span>
|
||
|
|
<p>Consider the
|
||
|
|
following measures when securing your network:</p>
|
||
|
|
<a name="wq95"></a>
|
||
|
|
<div class="notetitle" id="wq95">Note:</div>
|
||
|
|
<div class="notebody">The following
|
||
|
|
password considerations only apply if password protection is not active.</div>
|
||
|
|
<ol type="1">
|
||
|
|
<li>When application program security is used, specify SECURELOC(*VFYENCPWD).
|
||
|
|
This means that you only get to log on if BOTH your user profile name AND
|
||
|
|
password are the same on both systems.</li>
|
||
|
|
<li>The person responsible for network security ensures that each user has
|
||
|
|
a unique user ID throughout the network.</li>
|
||
|
|
<li>Have your system administrator set a limit on the number of consecutive
|
||
|
|
password attempts that are not valid for a given display device. When this
|
||
|
|
limit is reached, the device is then varied off. Set the limit with the system
|
||
|
|
value QMAXSIGN. This is only true for Display devices, not for APPC devices.</li>
|
||
|
|
<li>Users can sign on to more than one iSeries system with the same profile.
|
||
|
|
To limit the user profile to one sign-on, Set the system value (*SYSVAL) for
|
||
|
|
LMTDEVSSN parameter on either the Create User Profile (CRTUSRPRF) or Change
|
||
|
|
User Profile (CHGUSRPRF) command.</li></ol></li>
|
||
|
|
<li><span class="bold">Physical security considerations:</span>
|
||
|
|
<p>You are responsible
|
||
|
|
for the physical security of your system when you specify *NONE for the location
|
||
|
|
password (LOCPWD) parameter during APPC configuration. In this case, the iSeries system
|
||
|
|
does not validate the identity of a remote system when a session is being
|
||
|
|
established. However, you can still use application-level security if the
|
||
|
|
remote system supports it. For example, if the remote system is an iSeries system
|
||
|
|
with security level 20 or above. Security needs to be consistent across all
|
||
|
|
the systems in a network if intersystem access is to be controlled and yet
|
||
|
|
not unnecessarily restricted.</p></li></ul>
