What must be periodic
- evaluate the effectiveness of your measures and record the result [1]
- verify backups and test the procedures, the business continuity plan, the recovery plan and the crisis plan [2]
- check whether your direct suppliers meet your security requirements [3]
- check identities, authentication means and authorisations [4]
- evaluate the designation of people with security roles [5]
How often is periodic?
According to the explanatory memorandum, you determine and justify yourself, depending on your risks, which period is appropriate [6]. Transport companies also record in their management system which measures they monitor and measure, and when they measure and analyse and evaluate the results [12]. Record that choice; a period without justification is hard to defend in supervision.
Also in between
If you are specifically warned about a relevant vulnerability or threat, you assess immediately whether your measures must change and record that [7]. Transport companies also carry out periodic vulnerability scans where appropriate and record the results [8].
Cloud and IT service providers: at least annually
These articles do not apply to the digital providers referred to in Article 4 of the decree [9]. The European implementing regulation asks of them that the management body evaluates the security policy at least annually, and also after significant incidents or changes [10], and that they evaluate the risk assessment at least once a year [11].
