All information processing activities have an owner, the process owner.

All processing activities need to be registered and maintained, this is the responsibility of the process owner.

All processing activities need to be classified to determine the potential impact to the organization.

The CISO Office will publish and maintain a classification procedure.

Classifications are updated every 2 years or when major changes to the processing activity warrant re-classification.


Technical specification:
On this page (internal) it is explained how to add processing activities to the processing registry. Classification is a part of that process.

Last updated: 30-10-2020

All processing activities (with and without PII) need to be registered and maintained, this is the responsibility of the process owner.

The registration contains at least the classification of the processing activity, the process owner and a description of the IT services used for the activity.


Technical specification:
On this page (internal) it is explained how to add processing activities to the processing registry. Classification is a part of that process.

Last updated: 30-10-2020

IT services used in the processing activity are considered suitable according to their communicated IT Security Capability level.

Operating procedures for correct and secure usage of the IT services, delivered by the service, are followed.

The IT service offers appropriate functionality for uptime (Recovery Time Objective) and backups (Recovery Point Objective) for the data processing activity.


Technical specification:
When processing information, you normally make use of 1 or more IT services. For example, you could receive information in your email, store it locally on your managed laptop, modify it in an application and upload it to SharePoint. Each of the services you use needs to be appropriate for use.

What is appropriate is determined by the classification of the processing activity and the Security Level of the services you are using. UU services should be offered with a specific Security Level.

Last updated: 30-10-2020

Data processing activities should be processed and stored exclusively on organisationally managed (either contracted or governed by the organisation) hard-and software.


Technical specification:
Use only official UU managed hardware and supplied facilities to process Critical information.

Last updated: 08-09-2022

Users should adhere to internal best practices regarding email to avoid causing data breaches, to limit the impact in case data breaches happen. and to support forensics and impact if a data breach does happen.


Technical specification:

Last updated: 30-10-2020

Before processing sensitive data, individuals working with the data must agree to non-disclosure agreements that limit the legal room for distributing the data during and for a period after the activities take place. NDA’s also specify consequences of breaches of the agreement and are signed by the individuals.


Technical specification:
UU contracted employees adhere to the Code of Conduct that states they will treat information with the appropriate care and keep it secret. So if you only work with UU colleagues, you do not need NDA’s. If you work with external parties though, make sure they are contractually obligated to keep sensitive information secret.

Contact HRservicedesk@uu.nl for help with NDA’s for contractors.

Teams plan to have sufficient capacity to execute important tasks, also during holidays. There is monitoring on the capacity of the team and structural understaffing gets flagged and addressed. There are procedures in case of unplanned absence of team-members to continue with important processes.


Technical specification:

Last updated: 30-10-2020

Individuals in teams that are the only ones capable of performing specific tasks need to be identified as Single Points of Failure. Team leaders are responsible for identifying these individuals and transferring this knowledge to other employees and procedures. If this knowledge is non-transferable, more capable staff or a retainer with a supplier that can provide this expertise needs to be arranged.


Technical specification:

Data stored on portable storage devices is stored encrypted according to modern standards.


Technical specification:
Encryption of portable storage must follow the Dutch NCSC advice for bulk data encryption as described in the guideline on TLS, which can be found here: https://www.ncsc.nl/documenten?trefwoord=TLS%20versleuteling .

UU offers tools that are considered suitable, when used right, for the encryption of data on portable storage devices. See this page for an overview of services (encrypted USB/HDD, winzip with right settings, BoxCryptor, Bitlocker, ….). See this intranet page for more on encrypting your information: https://intranet.uu.nl/informatiebeveiliging-hoe-ga-ik-om-met-externe-harddisks-en-usb-sticks .

For the processing of data other than the primary process for which this data is collected, Terms of Use and agreements are available that detail how the data can and must be treated, also for internal processes. These Terms of Use have to be agreed to before the processing of data and the data owner remains responsible for the data and monitoring that the Terms of Use are adhered to.


Technical specification:
Data-owners are responsible for the data and remain so, even after granting access to others. This can be the case for developing new software or for research purposes. It is important that there are clear agreements on how data is handled when data classified as Critical on C-I-or -A is shared with others outside the process itself.

These agreements should look a lot like a Data Processing Agreement and contain many of the same clauses, such as how the information is secured and how incidents are treated.

Last updated: 5-6-2020

The identity of receiving and originating party is verified using (digital) signatures.


Technical specification:
Digital signatures must use cryptographic standards and public/private keypairs to sign documents, so they cannot be repudiated or tampered with.
S/MIME may be used for digital signing/verification. Contact secops@uu.nl for help with setting up your data transport in a secure manner.

Last updated: 30-10-2020

Suppliers are contractually obligated to adhere to the information security policies of the UU. All agreements made with the supplier apply to sub-contractors equally and are under the responsibility of the supplier.

Agreements with partners (including external researchers) include appropriate data management and security controls for the classification of the processing activity.


Technical specification:

Last updated: 30-10-2020

Before new suppliers of Information Technology products or services are contracted or engaged for the purpose of supporting processing activities with this classification or higher, official advice must be requested on the Information Security risks as seen by the CISO Office.

Last updated: 30-10-2020

Data can only be moved to hardcopy with express permission of the data owner.

Information Security policy and controls are equally applicable to hardcopy data.


Technical specification:
Do not print critically sensitive information, unless you have explicit permission to do so. You need to treat printed information as secure as digital information.

Last updated: 30-10-2020

In performance reviews, secure behaviour is discussed and part of the evaluation.


Technical specification:
Managers should make sure that working securely and attentively is something that is monitored and part of feedback. Reporting of (potential) risks and incidents should never be punished but rewarded and motivated, and are part of a positive review. Demonstrating the behaviours listed in DS.2.002 should be actively encouraged.

Last updated: 30-10-2020

Information is only distributed to people that have a legitimate need for it. Authentication details and tokens are never shared (not to colleagues or secretarial staff). Only the minimum amount of information that is needed for a purpose is shared, through channels appropriate for the level of data classification.


Technical specification:
Do not share credentials, logins or unnecessary information from your applications with anyone. This includes colleagues that may have to perform certain tasks or favours for you, use appropriate ways to achieve those goals.

Last updated: 30-10-2020

The organization has a social media policy. The CISO Office is consulted for the policy to address security aspects.

The Social Media policy distinguishes between acceptable and representative uses of Social Media for private use, and how Social Media representing the organization must be managed.

Social Media software is subject to the Information Security policies.

All individuals are informed of and adhere to the Social Media Policy.


Technical specification:
Remember when using Social Media that you are considered a representative of the organization. When in doubt whether statements may be considered offensive, local communication experts can always be consulted.

Scraping Social Media is a data processing activity that should not be performed without following the necessary steps listed in DS.1.002 and having performed the necessary Privacy checks.

Last updated: 30-10-2020

Where there are repeated security incidents, lessons will be drawn and the source of (repeated) incidents addressed in a structural manner, changing processes and supporting IT where appropriate.


Technical specification:
It can always happen that something goes wrong by accident, but if a process goes wrong in the same way multiple times, that is a good reason to critically evaluate if there are other ways to perform this process. If assistance is desired in seeing if there are more secure (and often more efficient) ways to perform a process, please consult informatiebeveiliging@uu.nl

Before commencement of processing activities all individuals working with data and systems have been identified using a nationally issued Identification Document.


Technical specification:
All contracted UU employees and contractors have had their identities validated before accounts have been provisioned. So if you work with UU colleagues, this has already been taken care of. However, if you work with people from outside our organisation, make sure their identities have been sufficiently validated before you exchange information.

Last updated: 5-6-2020

Before commencement of processing activities all individuals working with sensitive data and systems have basic background checks performed to determine integrity, suitability for the tasks and secure behaviour.


Technical specification:
At least 2 references are confirmed and contacted before the start of employment to attest to the integrity and qualities of the candidate.

Personnel is required to deliver a VOG (Dutch for: Verklaring Omtrent Gedrag, Declaration about Behaviour) covering relevant criminal history to this processing activity, or an international equivalent from local law enforcement.

A new VOG is required every 5 years. If a VOG cannot be obtained, the processing activities need to be ceased and the access of the individual revoked at first opportunity.

Last updated: 30-10-2020

Background verification is performed through a trusted third party that involves extensive screening for financial, national, criminal and other relevant factors that could influence the integrity and reliability of personnel before processing activities start. Background screening needs to be repeated every 10 years. If a screening finds issues, processing activities and access need to be revoked immediately and treated as a potential incident.


Technical specification:
We need to ensure that the integrity of people working in Critical roles is appropriate for their critical access. Contact HR and informatiebeveiliging@uu.nl to determine the appropriate level of screening.

Only the minimal amount of authorisations are given to individuals for their role and purpose in the processing activities.

Authorisations are only given for the minimum necessary duration the activities will take place.

Preferably these are given based on a role and not attached to individuals.


Technical specification:
This control is for data-owners. Make sure that only people that need access to data to perform their work activities have been granted that access. Do not give people additional access that is not needed. For example: share files with users from your SharePoint with read-only access if these users only need to read and comment.

If you can set roles, make sure that the roles have the minimal amount of privileges necessary for the tasks these people have to perform. A person can be assigned multiple roles, but make sure that there are no conflicting privileges in these roles.

Last updated: 30-10-2020

At least yearly a list of all users in the system is generated along with associated permissions. The data owner should have defined who should be allowed to have access (preferably based on roles) and all access rights should be reviewed by appropriate data owners. Actions taken based on the review are recorded and stored for 2 years.


Technical specification:
At least once every year, check who have permissions to view and modify data for which you are responsible. This includes network storage directories, online cloud storage, permissions in Office365 (Teams and SharePoint), etc… When in doubt if someone still needs access, confirm whether this is the case and remove all authorisations that are no longer needed.

Last updated: 30-10-2020

At least quarterly a list of all users in the system is generated along with associated permissions. The data owner should have defined who should be allowed to have access (preferably based on roles) and all access rights should be reviewed by appropriate data owners. A documented procedure is available for how the review is performed. Actions taken based on the review are recorded and stored for 2 years. If the authorisations are given based on role, the authorisations within the roles are part of the review as well.


Technical specification:
