Description

Failure to use a robust ACP to control a product could potentially compromise the integrity and availability of the MVS operating system and user data.

ℹ️ Check

Refer to the following report produced by the ACP Data Collection: - TSSCMDS.RPT(#RDT). If the ROSCOE Resource Class(es) is (are) defined in the Resource Definition Table (RDT) as follows, this is not a finding. RESOURCE CLASS = ROSRES RESOURCE CODE = X'hex code' ATTRIBUTE = MASK|NOMASK,MAXOWN(08),MAXPERMIT(044),ACCESS,DEFPROT ACCESS = NONE(0000),CONTROL(0400),UPDATE(6000),READ(4000) ACCESS = WRITE(2000),ALL(FFFF) DEFACC = READ

✔️ Fix

The ISSO will ensure the Product resource class(es) is (are) defined in the TSS RDT. The ISSO will issue one of the following commands to define the Product resource class(es): TSS REPLACE(RDT) RESCLASS(ROSRES) - MAXLEN(044) - ATTR(MASK|NOMASK,DEFPROT) - ACLST(NONE(0000),CONTROL(0400),UPDATE(6000),READ(4000),WRITE(2000),ALL(FFFF)) - DEFACC(READ) TSS ADDTO(RDT) RESCLASS(ROSRES) - RESCODE(hex-code) - ATTR(MASK|NOMASK,DEFPROT) - ACLST(NONE(0000),CONTROL(0400),UPDATE(6000),READ(4000),WRITE(2000),ALL(FFFF)) - DEFACC(READ)
