The research area at AAU is constantly evolving, and in recent years, the university's researchers have gained new opportunities to work with data that is of a socially important or critical nature (e.g. defence and military data).

The old data classification model with levels 0-3 was primarily based on personal data and did not include the appropriate measures for handling data of an even more critical nature.

Therefore, a major effort was initiated to develop a new data classification model at Aalborg University that could accommodate the exciting opportunities that the research area in particular attracts.

Please take a look at the new data classification model and use the tools to easily reclassify your data. In most cases, the level will remain the same.

If you are unsure about where your data fits in, please feel free to ask your questions via the Service Portal.

For systems that have been assigned a data classification level according to the old model, use can continue unchanged as a starting point. However, in case of doubt, it would be beneficial for the system owner to contact IT Security for a reassessment of the system.

Broadly speaking, the old four-stage model has been boiled down to the new levels, which are called 1-3, and a whole new level 4 has been added.

This means that many existing classifications will remain the same:

Classification 0 in the old model is now level 1. 

Classification 1 remains either 1 or moves up to 2.

Classification 2 remains either 2 or moves up to 3.

Classification 3 will remain level 3 in most cases.

Previously, there was no classification level that could accommodate the new level 4. Therefore, there is no direct correlation with the old data classification model at this level.
