All other users can have read access.
The installing Systems Programmer will identify and document the product data sets and categorize them according to who will have update and alter access and if required that all update and allocate access is logged. He will identify if any additional groups have update 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:

(Note: The resource class, resources, and/or resource prefixes identified below are examples of a possible installation. The actual resource class, resources, and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.)
When SECOPTS.OPERSEC=SAFPW is specified in ZNET0040, this is not applicable. This can be bypassed.
Ensure that all NetView resources and/or generic equivalents are properly protected according to the requirements specified in the NetView Resources table in the z/OS STIG Addendum. Additional details can be obtained in the IBM Tivoli NetView for z/OS Security Reference.
Use the NetView Resources table in the z/OS STIG Addendum. This table lists the resources and access requirements for NetView, ensure the following guidelines are followed:
The TSS resources and/or generic equivalents as designated in the above table are owned or DEFPROT is specified for the resource class.
The TSS resource access authorizations restrict access to the appropriate personnel as designated in the above table.

(Note: The data set identified above is an example of a possible installation. The data set is determined when the product is actually installed on a system through the product’s installation guide and can be site specific.)
SECOPTS.OPERSEC=SAFCHECK|SAFDEF
When SECOPTS.OPERSEC=SAFCHECK is used, it specifies that operator identification and password or password phrase checking is performed using an SAF security product. The operator identifier must also be defined in DSIOPF, and other attributes given to the operator at logon are taken from the specified profile for the operator in DSIPRF.
Security access checks are checked against the authority of the operator that occur when an operator tries to access a data set that is protected in the DATASET class of an SAF product or an MVS system command that is protected in the OPERCMDS class of an SAF product.
When SECOPTS.OPERSEC=SAFDEF is used, it specifies that operator identification and password or password phrase checking is done using an SAF security product. Authority to log on as a NetView operator is controlled through the APPL class. The operator identifier must be authorized to the resource name in the APPL class which represents the NetView program.
The attributes given to the operator at logon are defined in the NETVIEW segment of the user profile for the operator in the SAF product. For more information, refer to IBM Tivoli NetView for z/OS Security Reference.
When SECOPTS.OPERSEC=SAFDEF is specified, any value for SECOPTS.CMDAUTH can be used.
Additional details can be obtained in the IBM Tivoli NetView for z/OS Security Reference.
SECOPTS.CMDAUTH=SAF.FAIL|SAF.table
When SECOPTS.CMDAUTH=SAF.table is used, table specifies the backup table to be used for immediate commands and when the SAF product cannot make a security decision. This can occur when:
___ No resource name is defined in the NETCMDS class which protects or authorizes this command.
___ The NETCMDS class is not active.
___ The security product is not active.
When SECOPTS.CMDAUTH=SAF.FAIL is used, command authority checking will fail if the SAF product can reach no decision.
Additional details can be obtained in the IBM Tivoli NetView for z/OS Administration Reference.Review the member CxxSTYLE in the DSIPARM DD statement concatenation of the NetView CNMPROC STC procedure.
