[nicjar]

Link to the page of interest
https://rdmkit.elixir-europe.org/human_data#processing-and-analysing-human-research-data

Describe what you would change to the page

Check if there is any redundant information to be removed regarding Information Security that is now available on https://rdmkit.elixir-europe.org/data_protection (to be renamed to Data Security).

Dependent on #1264 being merged before making any changes

@vildead could you have a look at this while you are restructuring these pages? Thanks!

@nicjar can this issue be closed?

[vildead]

The overlap with 'Data security' page is still there. But #1264 is already merged so we can work on this one.
