What the act requires
Security in acquiring, developing and maintaining, with vulnerabilities, is point e [1]. The NIS2 directive names the same topic [2].
How the Cyberbeveiligingsbesluit elaborates this
The Cbb requires policy for acquiring software, hardware and services, processes for secure development if you develop yourself, and processes for maintenance with at least configuration and change management [3]. If you receive a targeted warning about a vulnerability, you assess whether your measures must change and you record that [4].
Patches and scans under the sector regulation
The Cbb has no separate patch article, the ministerial regulation for your sector does. For transport and chemicals that is the Cyberbeveiligingsregeling IenW [6]; for, among others, postal and courier services and food, equivalent regulations apply [7]. You apply security patches within a reasonable period after they become available, where appropriate after checking origin and integrity and after a test, unless the disadvantages of applying them outweigh the advantages; in that case you record with reasons why a patch is applied later or not at all [8]. Where appropriate you carry out periodic vulnerability scans and record the results, and you remedy vulnerabilities that pose a risk without delay or record with reasons why that does not happen or happens later [9].
What you record in practice
- security requirements when purchasing software, equipment and services
- which sources you follow for vulnerabilities in your systems
- patch records, and the justification with the weighing of disadvantages and advantages if a patch is not applied or applied later
- the results of vulnerability scans and what you did with them
- the recorded assessment after a targeted warning
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 [5] and Implementing Regulation (EU) 2024/2690 elaborates this measure. The obligation under Cbw Article 21 remains.
