Data storage guide

This guide will help you select the correct solution for storage and processing of information, including research data. The storage guide gives an overview of the storage solutions assessed by NTNU, provides information about designated usage, and tells you how to access the different solutions. In addition, the data collection guide and the storage guide provides information that can be used when creating data management plans.

Information security and classification

NTNU guidelines state that information must be classified in order to determine the value and identify the need for security and protection. The confidentiality classification describes what level of protection that is needed. These assessments must be made for all projects.

Classification of personal data

Research data is usually classified as internal (yellow) or confidential (red), and this also applies to research data containing personal data. Personal data is information and assessments that can be related to individual persons, either directly or indirectly. Examples include names, ID-numbers, e-mail, IP-addresses, photos, videos, interview recordings and transcribed interviews.

Some types of personal information are known as special categories of personal data (often called sensitive data). These types of data require additional protection and will usually fall in the confidential category. The same apples to data regarding criminal offenses or information about vulnerable groups or vulnerable situations.

Transfer of data

Remember that also the transfer of data to the chosen storage solution should be done according to the confidentiality classification. More information can be found in this Norwegian wiki, Sikker sending og mottak av filer og dokumenter. In general it is not recommended to store and transfer data using USB sticks or external hard drives, as these might be lost, can contain viruses and do not have backup. However, in certain this might be necessary, see the section on Physical storage media.
