In modern application workloads, organizations are often required to integrate their application with other parties such as Software-as-a-Service (SaaS) providers, customers applications, and business partners. These integrations may vary from granting one-time read access to ongoing static data consumption, to exposure of APIs or application components to a 3rd party provider. 

The purpose of this document is to provide a framework for securely connecting external entities such as customers or third parties. The document provides a usable list of security considerations in order to estimate the risk involved with the specific connectivity (first part of the document) and a technical checklist for the implementation of security controls (second part of the document).
