READ access can be given to auditors.

The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have WRITE and/or greater access and if required that all WRITE and/or greater access is logged.  He will identify if any additional groups have WRITE and/or greater access for specific data sets, and once documented he will work with the IAO to see that they are properly restricted to the ACP (Access Control Program) active on the system.

Data sets to be protected will be: 
SYS2.TDMF.
 SYS3.TDMF.

The following commands are provided as a sample for implementing data set controls: 

ad 'SYS2.TDMF.**' uacc(none) owner(sys2) -
	audit(success(update) failures(read)) -
	data('Transparent Data Migration Facility (TDMF) Install DS')

Verify that the accesses to the Transparent Data Migration Facility (TDMF) installation data sets are properly restricted.  If the following guidance is true, this is not a finding.
 
___	The RACF data set rules for the data sets restricts READ access to all authorized users.

___	The RACF data set rules for the data sets restricts WRITE and/or greater access to systems programming personnel.

___	The RACF data set rules for the data sets specify that all (i.e., failures and successes) WRITE and/or greater access is logged.

___	The RACF data set rules for the data sets specify UACC(NONE) and NOWARNING.</check-content></check></Rule></Group><Group id="V-18014"><title>ZB000040</title><description>&lt;GroupDescription&gt;&lt;/GroupDescription&gt;</description><Rule id="SV-24802r2_rule" severity="medium" weight="10.0"><version>ZTDM0040</version><title>Transparent Data Migration Facility (TDMF) configuration/parameter/option values are not specified properly.</title><description>&lt;VulnDiscussion&gt;Transparent Data Migration Facility (TDMF) configuration/parameter/option settings control the security and operational characteristics of product.

    a)       Check with your IOA or Systems Programming personnel and compile the list of Transparent Data Migration Facility (TDMF) Install                   data sets, Likely:
         1.	hlq.TDMF.**
         2.	From the Administrator Main Menu Choose Option  2;3  (Security Server Commands, Data Sets)
         3.	Type the resource names collected in option a.1 above at the prompt for Enter fully qualified (without quotes) data set or profile                       name:. 
         4.	Hit enter.  
         5.	Enter Y for Display covering profile? Y
         6.	Verify that the UACC is NONE
         7.	Verify that Audit Successes and Failures specifies UPDATE.
         8.	Tab down to Standard Access Permits and place an E next to the phrase and hit ENTER.
         9.	Verify that the data set rules for the product install data sets 
                a.  Permit  READ  access to all authorized users
                b.  Restrict UPDATE or higher access to systems programming personnel.
       10.	Tab down to Conditional Access  Permits line on the screen. If the phrase  *data is present* is found, enter  an E and hit                                 ENTER.
       11.	Verify  that  any additional data set rules for the product install data sets 
                a.  Permit  READ  access only  to authorized users
                b.  Restrict UPDATE or higher access to systems programming personnel
       12.	Repeat steps 2 through 10 for all datasets in option a.1
 
     b)       If  10a, 10b, 12a, and 12b are all true, there is NO FINDING.

     c)       If  10a, 10b, 12a, and 12b  are not true, this is a FINDING.
