Protecting critical business functions

December 22, 2022  //  FOUND IN: Updates & Resources,

In support of our mission and institutional driver for ransomware readiness, Michigan Medicine’s Information Assurance is partnering with critical business units to create a transparent and comprehensive inventory of Digital Critical Assets (DCA). 


IA will begin its work by reaching out to a business owner and subject matter experts (SME).

This effort will include both identification of initial inventory and an operational process to facilitate the ongoing identification, collection and management of digital critical assets to ensure accuracy and completeness. 

Maintaining an accurate inventory of DCAs supporting these systems and functions supports the strategic direction of proactively managing risks to our mission-critical services. An accurate inventory also allows for the prioritization and remediation of risk that may impact continuity of operations.
