There is an increasing interest in embedding the security in the design of digital enterprise architecture (EA) modeling platform to secure the digital assets.Access control management (ACM) is one of the key aspects of a secure digital enterprise architecture modeling platform design. Typical enterprise architecture modeling approaches mainly focus on the modeling of business, information, and technology elements. This draws our attention to this important question: how to model ACM for a secure digital EA modeling platform to ensure secure access to digital assets? This article aims to address this important research question in collaboration with our industry partner and developed an ontology-based ACM metamodel that can be used by enterprises to model their ACM for a particular situation. This research has been conducted using the well-known action-design research (ADR) method to develop and evaluate the ACM metamodel for the secure digital EA modeling platform.
