This is a brief blog posting on how to secure models in Odoo 14.  In your custom addon folder there is a folder called security.  Inside that folder you will edit the ir.model.access.csv.  The first row of this file list the following comma separated fields: id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink. 

  In this example, on the second row I typed the following: access_intake_form_intake_form,intake_form.intake_form,model_intake_form_intake_form,base.group_user,1,1,1,1 

  Notice the permission at the end of the entry.  The number one enables permissions.  The image below shows the visual representation of those permissions on the model.
