<h1 class="topictitle1">Monitor sign-on and password activity</h1>
|
|
<div><p>If you are concerned about unauthorized attempts to enter your
|
|
system, you can use the <span class="cmdname">PRTUSRPRF</span> command to help you monitor
|
|
sign-on and password activity.</p>
|
|
<div class="p">Here are several suggestions for using this report: <ul><li>Determine whether the password expiration interval for some user profiles
|
|
is longer than the system value and whether the longer expiration interval
|
|
is justified. For example, in the report, USERY has a password expiration
|
|
interval of 120 days. </li>
|
|
<li>Run this report regularly to monitor unsuccessful signon attempts. Someone
|
|
who is trying to break into your system may be aware that your system takes
|
|
action after a certain number of unsuccessful attempts. Each night, the would-be
|
|
intruder might try fewer times than your QMAXSIGN value to avoid alerting
|
|
you to the attempts. However, if you run this report early each morning and
|
|
notice that certain profiles often have unsuccessful signon attempts, you
|
|
might suspect that you have a problem.</li>
|
|
<li>Identify user profiles that have not been used for a long time or whose
|
|
passwords have not been changed for a long time.</li>
|
|
</ul>
