Security Bulletin: Data protection rules and policies are not enforced on virtualized objects

Security Bulletin


Summary

This problem is applicable for IBM Cloud Pak for Data 3.0.1 environments that have both Data Virtualization and Watson Knowledge Catalog add-ons. This problem is relevant only when using Data Virtualization configured for Watson Knowledge Catalog data policy enforcement. The "Policy enforcement" setting in "Service settings" is disabled by default. If this has not been changed, then the rest of this note is not applicable. If "Policy enforcement" setting in "Service settings" is enabled and data protection rules in Watson Knowledge Catalog are defined in Watson Knowledge Catalog (WKC), initially the rules will be observed to be enforced in Data Virtualization. However, after a while the rules may stop being enforced in Data Virtualization. This is a known issue that happens when a data asset in a catalog is not modified in any 7-day period, which leads to its expiration from the policy service cache.
