Hardening or system hardening in the context of S2C can be seen as the collection of tools, techniques, and best practices in place to reduce vulnerability related to S2C. The goal of systems hardening is to reduce security risk by eliminating potential attack vectors and condensing the system's attack surface.

The different modules of S2C are running on cloud infrastructure hosted via two hosting providers, Microsoft Azure and Amazon Web Services. This page describes the hardening measures in place for both providers. See page XXX for details on which modules are hosted through which provider.

Microsoft Azure

The following hardening measures are in place for the S2C modules hosted on Microsoft Azure:
