Response plan

  • Your data breach response starts with a high-level and detailed plan of your entity’s strategy for containing, assessing, and managing the incident from start to finish.


Why do you need a data breach response plan?

  • A data breach response plan enables entity’s to respond quickly to a data breach.
  • A quick response can reduce the likelihood of affected individuals suffering harm. It can also lessen financial or reputational damage to the entity that experienced the breach.
  • Preserve and build public trust

An effective data breach response can support consumer and public confidence in an entity’s respect for individual privacy, and the entity’s ability to manage personal information in accordance with community expectations.

What is a data breach response plan?

  • A data breach response plan sets out the steps, roles and responsibilities involved in managing a data breach.
  • It is important for staff to be aware of where they can physically access the data breach response plan on short notice and in writing.
  • How regularly you test your plan will depend on your circumstances, including the size of your entity, the nature of your operations, the possible adverse consequences to an individual if a breach occurs, and the amount and sensitivity of the information you hold. It may be appropriate in some instances that a review of the plan coincides with the introduction of new products, services, system enhancements, or such other events which involve the handling of personal information.
