Vulnerability discussion

(RACF0300: CAT II) The ERASE ALL specifies that data management is to erase all scratched data sets including temporary data sets. NOERASE specifies that no DASD data sets are erased when deleted.The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during migration process or contingency plan activation.

The IAO will ensure that ERASE SETROPTS value is set to ERASE()on unclassified systems. On classified systems it is set to ERASE(ALL) this allows DASD datasets to be erased when deleted. Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified in the example below: The RACF Command SETR LIST will show the status of RACF Controls including the status of the ERASE options. (1) For Classified systems, issue the command SETR ERASE(ALL) to enable Erase On Scratch for all datasets. (2) For Unclassified systems, the site can choose between SETR ERASE(ALL) to enable Erase On Scratch for all datasets or SETR ERASE() to enable Erase On Scratch and allow activation in individual dataset profiles via the command ALD '' ERASE.
