With z/OS 2.3 IBM now delivers application transparent,
policy-controlled dataset encryption in IBM z/OS. z/OS V2.3 replaces
application development efforts with transparent, policy-based data set
encryption with an enhanced data protection not only for z/OS, DB2, IMS
data sets and zFS file systems, but also for Coupling Facility
structures to give users the ability to encrypt data without needing to
make costly application program changes. This video explains and gives
the details on how to encrypt Coupling Facility list and cache
structures, and how to encrypt your CF logstream data. The goal is to
encrypt and decrypt CF data as it is sent to and returned from the CF
protecting data in flight, with no application changes.
