The Industrial Internet Consortium (IIC) announced the publication of the IIC IoT Security Maturity Model: Description and Intended Use white paper. Building on concepts identified in the IIC Industrial Internet Security Framework, the Security Maturity Model (SMM) defines levels of security maturity for a company to achieve based on its security goals and objectives as well as its appetite for risk. This enables decision makers to invest in only those security mechanisms that meet their specific requirements.
Security Maturity Model Process
Organizations apply the SMM by following a process. First, business stakeholders define security goals and objectives, which are tied to risks. Technical teams within the organization, or third-party assessment vendors, then map these objectives into tangible security techniques and capabilities and identify an appropriate security maturity level. Following this, organizations develop a security maturity target, which includes industry and system-specific considerations, and capture the current security maturity state of the system.
The IIC IoT Security Model: Description and Intended Use white paper is an introduction to the SMM. The IIC Security Maturity Model: Practitioners Guide will be released in the coming months and will contain the technical guidance for assessment and enhancement of security maturity level for appropriate practices.
