Every department is managed by Shared Services Canada, so we work hand in glove with Shared Services Canada as well as with the department CIO and Treasury Board to ensure that the necessary measures are in place to protect from denials of service.
That said, a denial of service, as you mentioned, does not automatically mean that data is stolen. However, we do continue to work with everyone to ensure that the necessary measures are in place to add robustness and rigour to the protection.
