Example Secure Configuration

This section aggregates all of the security recommendations from the previous sections. Note, again, that some adjustment is likely to be necessary depending on your environment; for example, this set of configuration values presumes that SSL termination is happening in Posit Workbench, that Workbench is the only application running on its domain, and that it is never embedded in another page.

Therefore, use these files as a starting point rather than copying and pasting them into your own system.
