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

Security Bulletin


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.

*The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score. Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin.


According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
