Fix Recommendation

Review the data set access authorizations defined to the ACP for the Base TCP/IP component. Configure these data sets to be protected in accordance with the following rules:

WRITE and ALLOCATE access to product data sets is restricted to systems programming personnel (i.e., SMP/E distribution data sets with the prefix SYS1.TCPIP.AEZA and target data sets with the prefix SYS1.TCPIP. SEZA).

WRITE and ALLOCATE access to the data set(s) containing the Data and Profile configuration files is restricted to systems programming personnel.

Note: If any INCLUDE statements are specified in the Profile configuration file, the named MVS data sets have the same access authorization requirements.

WRITE and ALLOCATE access to the data set(s) containing the Data and Profile configuration files is logged.

Note: If any INCLUDE statements are specified in the Profile configuration file, the named MVS data sets have the same logging requirements.

WRITE and ALLOCATE access to the data set(s) containing the configuration files shared by TCP/IP applications is restricted to systems programming personnel.
