The response was exemplary. It was immediately on site and connecting into the network and advising people. I had no sense at all there was an inadequate response or that it was unavailable to do it. I really felt it was very professional. It immediately brought in FireEye, the security consultancy from California with which it has an existing relationship. It is the organisation that carried out the capacity review in the first place. It had offers of support from security consultants who are academics, from the Garda and from the Defence Forces. Many people were on site within a short period of time. That day, they were 300 people available to work on it. Really, the key people to carry out the work were the HSE's own IT staff because they are the people who know their own systems. They have been critical to this. They worked through the first few nights and it was day and night work to get the systems back. I am very happy with how it has gone but there will be a review of how the attack happened and how the response went. Once the systems are back online and the patients are getting all their services again that will be the time to carry out an investigation.
