Learn about the General Data Protection Regulation (GDPR) and where VMware Tanzu Application Service for VMs (TAS for VMs) might store personal data.

GDPR came into effect on May 25, 2018 and affects any company processing the data of EU citizens or residents, even if the company is not EU-based. The GDPR sets forth how companies can handle privacy issues, securely store data, and respond to security breaches.

Process personal data

The GDPR grants data subjects certain rights, such as the right to obtain a copy of their personal data, object to the processing of personal data, and the right to have their personal data erased. Organizations subject to GDPR need to ensure that they can address and respond to requests by data subjects if they are processing their personal data.

Article 4, Section 1 of the GDPR defines personal data as follows:

'personal data' is any information relating to an identified or identifiable natural person ('data subject'); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person;

For more information, see the GDPR text.

Personal data can be collected, stored, and processed in a TAS for VMs deployment. VMware has performed a review of TAS for VMs components and determined that personal data might reside in the areas discussed in the following sections.

Where personal data might reside

The following sections explain how different TAS for VMs components collect personal data.

User Account and Authentication (UAA)

UAA is an open-source Cloud Foundry component that provides identity management features and identity-based security for apps and APIs. For more information, see User Account and Authentication.

Cloud Foundry API

The Cloud Foundry API release contains several components, including the Cloud Controller. For more information, see the Cloud Foundry API release README.

Routing

By default, the Gorouter logs include the X-Forwarded-For header, which might include the originating client IP. Under GDPR, client IP addresses can be considered personal data.

Deactivate client IP logging

In TAS for VMs v2.0 and later and Elastic Runtime v1.12, you can deactivate logging of client IP addresses in the Gorouter.

To deactivate logging of client IP addresses:

  1. Go to the Tanzu Operations Manager Installation Dashboard and click the TAS for VMs or Elastic Runtime tile.

  2. Click Networking.

  3. In Client IP Logging::

    • If the source IP address exposed by your load balancer is its own IP address, select Do not log X-Forwarded-For header.
    • If the source IP address exposed by your load balancer belongs to the downstream client, select Do not log source IP or X-Forwarded-For header.

  4. Click Save.

  5. Return to the Tanzu Operations Manager Installation Dashboard, click Review Pending Changes, and click Apply Changes to redeploy.

Diego

Diego is the container management system for TAS for VMs. For more information, see Diego Components and Architecture.

GDPR Workflow What personal data is collected? When is it collected? Where is it stored? How is it processed? Who has access to it? How can I delete it?
Business Execution Executing apps and tasks No personal data is collected explicitly, but personal data might be encoded in app file contents or runtime metadata such as environment variables or start commands. Runtime metadata is collected when Cloud Controller submits work specification to the Diego BBS API. File contents are collected when Diego schedules an app or a task on a Diego Cell. Runtime metadata is stored in the Diego BBS DB. App file contents are cached on Diego Cells. Runtime metadata is used to start processes inside app instance containers and to configure their environment. App file contents are presented as part of the app instance container filesystem. Platform operators and other developers with access to the Cloud Controller space containing that app can view the data.
  • To delete the runtime metadata stored in the Diego BBS DB, stop the app or cancel the task that includes that data.
  • To delete the app file contents stored in the running app and task containers, stop the app or cancel the task to destroy the containers. To get rid of the app file contents stored in the download cache on the Diego Cells, recreate the Diego Cell VMs.
Reports/Logs SSH proxy logs TAS for VMs user access. UAA user name and ID When the user authenticates for SSH access to an app. The data is stored in a log file collocated with the SSH proxy instance handling the authentication request. This log file can also have its contents forwarded to a remote syslog destination. No processing of the local log file is done automatically. If the log file contents are forwarded to a log aggregation service, they might be parsed and processed arbitrarily. Only platform operators have access to the local log file. Platform operators or auditors have access to these log contents in a downstream log aggregation service. To delete the log lines containing the user ID:
  1. Run bosh recreate on the VMs hosting the SSH proxy processes to remove all the logs on ephemeral disk.
  2. bosh ssh into the VMs hosting the SSH proxy processes and remove specific log lines containing user IDs.
  3. Scrub corresponding log lines from any log aggregation service.

Notifications Service

The Notifications Service allows you to configure components of TAS for VMs to send emails to end users. For more information, see Getting Started with the Notifications Service.
