Controls and Procedures#

Media Disposal Process#

IT and Security is responsible to ensure media containing critical / sensitive data is disposed securely in the following manner:

  • The methods of destruction, disposal, and reuse are reassessed periodically, based on current technology, accepted practices, and availability of timely and cost-effective destruction, disposal, and reuse technologies and services. This may include

    • Secure wipe;
    • Physical destruction;
    • Destruction of encryption keys (if the data on the media is encrypted using a strong algorithm such as AES-256).

  • If the records have been requested in the course of a judicial or administrative hearing, a qualified protective order will be obtained to ensure that the records are returned to the organization or properly destroyed/disposed of by the requesting party.

  • All Tuna Subcontractors provide that, upon termination of the contract, they will return or destroy/dispose of all patient health information. In cases where the return or destruction/disposal is not feasible, the contract limits the use and disclosure of the information to the purposes that prevent its return or destruction/disposal.

  • In the cases of a Tuna Customer terminating a contract with Tuna and no longer utilize Tuna Services, data will be returned or disposed per contract agreement or Tuna Platform use terms and conditions. In all cases it is solely the responsibility of the Tuna Customer to maintain the safeguards required of laws and regulations once the data is transmitted out of Tuna environments.
