Password management? User management? How do you maintain who or what has SSH and RDP access? How do you provide secure access to internal websites or even other data sources? How do you know your admins and analysts and end users are accessing them securely? How do you know who has keys sitting in their downloads folder? How do you track any of it?

This post aims to provide readers with a good baseline for a secure G Suite configuration and some recommendations related to preparing for worst case scenario.
