There are LOGONIDs associated with started tasks that have the MUSASS requirement but do not have both the MUSASS and NO-SMC specified in corresponding LOGONID records.

Associated with IA controls: DCCS-1, DCCS-2

SV-162r1_rule There are LOGONIDs associated with started tasks that have the MUSASS requirement but do not have both the MUSASS and NO-SMC specified in corresponding LOGONID records.

Vulnerability discussion

If the LOGONID does not have the MUSASS attribute specified, there is no individual accountability within the associated address space.If NO-SMC is not specified the potential for VSAM data set corruption exists.

a) Refer to the following reports produced by the ACF2 Data Collection: - ACF2CMDS.RPT(ATTSTC) - ACF2CMDS.RPT(ATTMUASS) Automated Analysis Refer to the following report produced by the ACF2 Data Collection Checklist: - PDI(ACF0610) b) Identify the started tasks that have a Multi-User Single Address Space System (MUSASS) requirement. c) If every logonid associated with a started task that has the MUSASS requirement has the MUSASS and NO-SMC attributes, there is NO FINDING. d) If any logonid associated with a started task that has the MUSASS requirement does not have the MUSASS and NO-SMC attributes, this is a FINDING.

Fix text

The IAO will ensure that if the STC is a Multi User Single Address Space System (MUSASS), the STC logonid has the MUSASS and NO-SMC attributes. If the started task (STC) is a Multi User Single Address Space System (MUSASS), the STC logonid will also have the following attributes: MUSASS NO-SMC Example: SET LID INSERT logonid STC MUSASS NO-SMC
