What the act requires
Policy and procedures for cryptography and, where appropriate, encryption are point h [1]. The NIS2 directive names the same topic [2].
How the Cyberbeveiligingsbesluit elaborates this
The Cbb requires established, written policy with processes on cryptography. It states at least in which cases you use cryptography, which types of encryption you use, and who is responsible for implementation and key management [3].
What you record in practice
- where you use encryption: connections with on-board computers, customer portals, laptops, backups
- which types of encryption and how you apply them
- who manages the keys and certificates
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.
