<div><p>You can prevent intentional and unintentional access to the data
|
|
resources of a system by the DDM user.</p>
|
|
<div class="section"><p>Access to data in the DDM environment can be limited—or prevented
|
|
altogether—by a server-level network attribute, the DDMACC parameter on the <span class="cmdname">Change
|
|
Network Attributes (CHGNETA)</span> command on the server. This attribute
|
|
allows the server (as a target server) to prevent all remote access; or it
|
|
allows the server to control file access by using standard authority to files
|
|
and, further, by using an optional user exit program to restrict the types
|
|
of operations allowed on the files for particular users.</p>
|
|
</div>
|
|
<div class="section"><p>To provide adequate security, you might need to set
|
|
up additional user profiles on the target server, one for each source server
|
|
user who can have access to one or more target server files. Or, a default
|
|
user profile should be provided for multiple source server users. The default
|
|
user profile is determined by the communications entry used in the subserver
|
|
in which the target jobs are run.</p>
