<div><p>This topic describes the purpose of security audits.</p>
|
|
<div class="p">People audit their system security for several reasons: <ul><li>To evaluate whether the security plan is complete.</li>
|
|
<li>To make sure that the planned security controls are in place and working.
|
|
This type of auditing is usually performed by the security officer as part
|
|
of daily security administration. It is also performed, sometimes in greater
|
|
detail, as part of a periodic security review by internal or external auditors.</li>
|
|
<li>To make sure that system security is keeping pace with changes to the
|
|
system environment. Some examples of changes that affect security
|
|
are:<ul><li>New objects created by system users</li>
|
|
<li>New users admitted to the system</li>
|
|
<li>Change of object ownership (authorization not adjusted)</li>
|
|
<li>Change of responsibilities (user group changed)</li>
|
|
<li>Temporary authority (not timely revoked)</li>
|
|
<li>New products installed</li>
|
|
</ul>
|
|
</li>
|
|
<li>To prepare for a future event, such as installing a new application, moving
|
|
to a higher security level, or setting up a communications network.</li>
|
|
</ul>
|
|
</div>
|
|
<p>The techniques described here are appropriate for all these situations.
|
|
Which things you audit and how often depends on the size and security needs
|
|
of your organization.</p>
|
|
<p>Security auditing involves using commands on your system and accessing
|
|
log and journal information. You can create a special profile to be used by
|
|
someone doing a security audit of your system. The auditor profile needs *AUDIT
|
|
special authority to change the audit characteristics of the system. Some
|
|
of the auditing tasks suggested in this chapter require a user profile with
|
|
*ALLOBJ and *SECADM special authority. Set the password for the auditor profile
|
|
to *NONE when the audit period has ended.</p>
|
|
<p>For more details on security auditing, see Chapter 9, <span class="q">"Auditing System
|
|
Security,"</span> in the <cite>iSeries™ Security Reference</cite>.</p>
