What the act requires
Point j requires, when appropriate, multi-factor or continuous authentication and secure communication [1]. The NIS2 directive names the same topic [2].
How the Cyberbeveiligingsbesluit elaborates this
The Cbb has no separate article on multi-factor authentication; the access policy of Cbb Article 15 is where you record which access is secured with which means. For secure emergency communication, the crisis plan of Cbb Article 9(5) names the available emergency provisions [3]. The ministerial regulation for your sector does require strong identification, authentication and authorisation procedures for privileged accounts and system administrator accounts [7]; for transport and chemicals that is the Cyberbeveiligingsregeling IenW [5], for, among others, postal and courier services and food an equivalent regulation [6].
What you record in practice
- for which access you use multi-factor authentication, and why not where you do not
- strong authentication for administrator accounts, and a decision for remote access
- how your organisation communicates if email or telephony fails
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.
