Hi Guillermo.
Not Ben nor Trent here, but I might be able to help, if what I will show you is not known by you already.
First, you will use the Security Editor from the StrataFrame menu at design time and create your Permissions, Restrictions, pre-built Roles, Users if necessary. These all will go to the SF Database.
Now, in your DDT project, you will import the Security tables' structures, as you can see in the figure bellow.
After that, click on Deployment Data and on the toolbar, Create new packages using the Deployment Package Wizard. Have a look at the following picture.
Following the wizard that will open, choose the Role Based Security Data and that will import all your data to be deployed.
That should be it. Your package will create your security structures and deploy the data on your production server.
Hope I got that right to you.
