This document, the “IoT Security Maturity Model: Description and Intended Use” (SMM) is the first of two documents covering the SMM and provides an introduction to the SMM. The second document “IoT Security Maturity Model: Practitioners Guide” will provide the details on the SMM. Deciding where to focus limited security resources is a challenge for most organizations given the complexity of a constantly changing security landscape. The Goal of the SMM is to provide a path for providers of Industrial Internet of Things products and services, to assist in evaluating the need to invest in security mechanisms that meet necessary requirements without over-investing in unnecessary security mechanisms. The SMM seeks to help organizations identify the appropriate approach for effective enhancement of these practices where needed.
