Ensure that LNKAUTH=APFTAB is specified in the IEASYSxx members currently active parmlib data sets

ÉlevéeNiveau 1Revue manuelleibm-z

Description

Specifying LINKAUTH=APFTAB in the IEASYSxx member(s) currently active PARMLIB data set(s) allows libraries other than those designated as APF to contain authorized modules by adding to this list all libraries in the LNKLST concatenation when accessed as part of the linklist concatenation. Failure to specify LINKAUTH=APFTAB allows libraries other than those designated as APF to contain authorized modules which could bypass security and violate the integrity of the operating system environment.
