Description
MVS data sets provide the configuration, operational, and executable properties of WebSphere MQ. Some data sets are responsible for the security implementation of WebSphere MQ. Failure to properly protect these data sets may lead to unauthorized access. This exposure could compromise the availability, integrity, and confidentiality of system services, applications, and customer data.
