After-the-fact supervision of important entities
The powers towards an important entity apply only if the competent authority has evidence, an indication or information of a possible infringement [1].
What the supervisory authority can then do
- carry out or have carried out a security scan, at its own cost [2]
- require you to have an independent expert investigate whether you comply with the act, with the results and the implementation of recommendations within a reasonable period; the cost is as a rule yours [3]
- give a binding instruction [4]
- require you to make parts of an infringement public [8]
The difference with essential entities
For an essential entity that condition is not in the act. There the authority can, among other things, have a security scan carried out on the basis of risk assessment criteria [5] and require an audit [6]. It can also appoint an independent monitoring officer for a certain period, at the cost of the entity [7].
What you can do
Make sure you can show your measures and choices: the policy, the risk analysis and the recorded evaluations. An audit is simpler if those documents are in order.
