Vulnerability discussion

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 one 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 a migration process or contingency plan activation.

The IAO will ensure that the RESVOL GSO value is set to Volmask(-). Any other setting requires documentation justifying the change. Ensure the GSO RESVOLS record values conform to the following requirements. VOLMASK(-) Example: SET C(GSO) INSERT RESVOLS VOLMASK(-) F ACF2,REFRESH(RESVOLS) NOTE: Local changes will be justified in writing with supporting documentation.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.
