<h1 class="topictitle1">Save file security</h1>
|
||
|
|
<div><p>The authority you grant for a save file is the same as for any file. Be
|
||
|
|
careful when granting authority for save files. The authority you grant to
|
||
|
|
the save file allows access to objects in the save file. For example, the
|
||
|
|
same file can be read from and written to by a high-level language program.
|
||
|
|
The authority you grant for a particular save file should depend on what objects
|
||
|
|
are in the file.</p>
|
||
|
|
<p>Consider the following factors when granting authorities to save files: </p>
|
||
|
|
<ul><li>A user with use (*USE) authority can read records and restore objects
|
||
|
|
from the save file. This user can save the contents of the save file to tape
|
||
|
|
or optical media.</li>
|
||
|
|
<li>A user with use (*USE) and add (*ADD) authority can write records and
|
||
|
|
save objects in a save file.</li>
|
||
|
|
<li>A user with object operational (*OBJOPR) and object management (*OBJMGT)
|
||
|
|
authority can clear the contents of a save file using the CLRSAVF command.
|
||
|
|
The clear operation is required first when replacing existing records in a
|
||
|
|
save file.</li>
|
||
|
|
<li>A user with either save system (*SAVSYS) special authority or object existence
|
||
|
|
(*OBJEXIST) authority for the file can save the description and contents.</li>
|
||
|
|
</ul>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Digital signature for a save file</h4><p>The system verifies
|
||
|
|
any digital signatures present on the save file each time you display the
|
||
|
|
save file or use the save file in a restore operation. If the signature is
|
||
|
|
not valid you cannot display or use the save file in a restore operation.
|
||
|
|
The Verify Object on Restore (QVFYOBJRST) system value does not affect the
|
||
|
|
verification of save files. Therefore, the system verifies the signature every
|
||
|
|
time you display the save file or use the save file in a restore operation.</p>
