What the act requires
Incident handling is the second mandatory topic of the duty of care [1]. The NIS2 directive names the same topic [2].
How the Cyberbeveiligingsbesluit elaborates this
The Cbb requires policy, fixed roles and processes for the whole cycle: detecting in time, analysing and assessing, responding and recovering, documenting, reporting and learning. Relevant events are logged; you set the retention period yourself in advance [3].
What you record in practice
- an established policy for incident handling
- who does what in an incident, also outside office hours and in planning
- which systems you log, how long you keep log files and how you protect them
- how an incident flows into the 24-hour reporting duty
Does this also apply to cloud and IT service providers?
If your company falls under Cbb Article 4 (among others cloud, data centres and managed (security) services), Cbb Articles 6 to 18 do not apply [4] and Implementing Regulation (EU) 2024/2690 elaborates this measure. The obligation under Cbw Article 21 remains.
