<h1 class="topictitle1">Restrict save and restore capability</h1>
|
||
|
|
<div><p>Part of your security system should be controlling users' save
|
||
|
|
and restore capabilities.</p>
|
||
|
|
<p>Most users do not need to save and restore objects on your system. The
|
||
|
|
save commands provide the possibility of copying important assets of your
|
||
|
|
organization to media or to another system. Most save commands support save
|
||
|
|
files that can be sent to another system (by using the SNDNETF file command)
|
||
|
|
without having access to media or a save/restore device. </p>
|
||
|
|
<p>Restore commands provide the opportunity to restore unauthorized objects,
|
||
|
|
such as programs, commands, and files, to your system. You can also restore
|
||
|
|
information without access to media or to a save/restore device by using save
|
||
|
|
files. Save files can be sent from another system by using the SNDNETF command
|
||
|
|
or by using the FTP function. </p>
|
||
|
|
<div class="p">Following are suggestions for restricting save and restore operations on
|
||
|
|
your system: <ul><li>Control which users have *SAVSYS special authority. *SAVSYS special authority
|
||
|
|
allows the user to save and restore objects even when the user does not have
|
||
|
|
the necessary authority to the objects.</li>
|
||
|
|
<li>Control physical access to save and restore devices.</li>
|
||
|
|
<li>Restrict access to the save and restore commands. When you install i5/OS™ licensed
|
||
|
|
programs, the public authority for the RSTxxx commands is *EXCLUDE. Public
|
||
|
|
authority for the SAVxxx commands is *USE. Consider changing the public authority
|
||
|
|
for SAVxxx commands to *EXCLUDE. Carefully limit the users that you authorize
|
||
|
|
to the RSTxxx commands.</li>
|
||
|
|
<li>Use the QALWOBJRST system value to restrict restoration of system-state
|
||
|
|
programs, programs that adopt authority, and objects that have validation
|
||
|
|
errors.</li>
|
||
|
|
<li>Use the QVFYOBJRST system value to control restoring signed objects on
|
||
|
|
your system.</li>
|
||
|
|
<li>Use the QFRCCVNRST system value to control the recreation of certain objects
|
||
|
|
being restored on your system.</li>
|
||
|
|
<li>Use security auditing to monitor restore operations. Include *SAVRST in
|
||
|
|
the QAUDLVL system value, and periodically print audit records that are created
|
||
|
|
by restore operations. </li>
|
||
|
|
</ul>
