Title

JESNEWS rewsources are not protected in accordance with security requirements. (Cat II impact)

Discussion

JES2 spool resources include all SYSOUT, SYSLOG, JESTRACE, and JESNEWS data sets. Failure to properly control JES2 spool resources could result in unauthorized personnel accessing job output, system activity logs, and trace data containing userid and password information. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

NOTE: JES2 is typically the name of the JES2 subsystem. Refer to the SUBSYS report and locate the entry with the description of PRIMARY JOB ENTRY SUBSYSTEM. The SUBSYSTEM NAME of this entry is the name of the JES2 subsystem. 2) Access authorization to the JES2.UPDATE.JESNEWS resource in the OPERCMDS class restricts CONTROL access to the appropriate personnel (i.e., users responsible for maintaining the JES News data set) and all access is logged. c) If both of the items in (b) are true, there is NO FINDING. d) If either item in (b) is untrue, this is a FINDING.
