I assume you'll be publishing this to Tableau Server? If so, each tab in the workbook will publish as a "View" and you should be able to set different security on each view. See Set Permissions on Individual Content Resources
thanks for your reply

access to users

Setting permissions for a user to see only one tab in a dashboard is a functionality that is not built into Tableau Server.
