Commitment to system integrity

System Integrity State-
ment and subsequent statements for OS/390
®
and z/OS
stand as a symbol of IBM’s confi dence and commitment to
the z/OS operating system. Today, IBM reaffi rms its com-
mitment to z/OS system integrity.
IBM’s commitment includes designs and development
practices intended to prevent unauthorized application
programs, subsystems, and users from bypassing z/OS
security—that is, to prevent them from gaining access,
circumventing, disabling, altering, or obtaining control of
key z/OS system processes and resources unless allowed
by the installation. Specifi cally, z/OS “System Integrity” is
defi ned as the inability of any program not authorized by
a mechanism under the installation’s control to circumvent
or disable store or fetch protection, access a resource pro-
tected by the z/OS Security Server (RACF), or obtain con-
trol in an authorized state; that is, in supervisor state, with
a protection key less than eight (8), or Authorized Program
Facility (APF) authorized. In the event that an IBM System
Integrity problem is reported, IBM will always take action to
resolve it.
IBM’s long-term commitment to System Integrity is unique
in the industry, and forms the basis of the z/OS industry
leadership in system security. z/OS is designed to help you
protect your system, data, transactions, and applications
from accidental or malicious modifi cation. This is one of
the many reasons System z remains the industry’s premier
data server for mission-critical workloads.
