AE6 - Auditing z/OS to Generally Accepted Security Practices (GASP) - Version 1 - Unlike professional accountants who can rely on the long- standing rubric of Generally Accepted Accounting Practices (GAAP) as a basis to measure their actions and client processes, there is no such a standard for z/OS Security professionals to follow. The z Exchange seeks to resolve this void and address the z/OS skills challenge head on by opening up to our community a conversation that we hope will culminate in a first ever statement of Generally Accepted Security Practices (GASP) for z/OS.
