<h1 class="topictitle1">Avoid default passwords</h1>
|
||
|
|
<div><p>When you create a new user profile, the default is to make the
|
||
|
|
password the same as the user profile name.</p>
|
||
|
|
<p>Default passwords provide an opportunity for someone to enter your system,
|
||
|
|
if someone knows your policy for assigning profile names and knows that a
|
||
|
|
new person is joining your organization.</p>
|
||
|
|
<p>When you create new user profiles, consider assigning a unique, non-trivial
|
||
|
|
password instead of using the default password. Tell the new user the password
|
||
|
|
confidentially, such as in a “Welcome to the System” letter that outlines
|
||
|
|
your security policies. Require the user to change the password the first
|
||
|
|
time that the user signs on by setting the user profile to <span class="cmdname">PWDEXP(*YES)</span>.</p>
|
||
|
|
<div class="p">You can use the <span class="cmdname">Analyze Default Passwords (ANZDFTPWD)</span> command
|
||
|
|
to check all the user profiles on your system for default passwords. When
|
||
|
|
you print the report, you have the option of specifying that the system should
|
||
|
|
take action (such as disabling the user profile) if the password is the same
|
||
|
|
as the user profile name. The <span class="cmdname">ANZDFTPWD</span> command prints
|
||
|
|
a list of the profiles that it found and any action that it took.<div class="note"><span class="notetitle">Note:</span> Passwords
|
||
|
|
are stored on your system in one-way encrypted form. They cannot be decrypted.
|
||
|
|
The system encrypts the specified password and compares it to the stored password
|
||
|
|
just as it would check a password when you sign on to the system.
|
||
|
|
If you are auditing authority failures (*AUTFAIL), the system will write a
|
||
|
|
PW audit journal entry for each user profile that does not have a default
|
||
|
|
password (for systems running V4R1 or earlier releases). Beginning with V4R2,
|
||
|
|
the system does not write PW audit journal entries when you run the <span class="cmdname">ANZDFTPWD</span> command.</div>
