Deriving Zero Trust–Oriented Security Scenarios from Architectural Requirements

This repository presents a systematic method for deriving Zero Trust (ZT)-oriented security quality attribute scenarios from architecturally significant security requirements. The approach identifies relevant quality attributes, decomposes them into Zero Trust-based softgoal trees, and maps them to concrete architectural scenarios. A case study demonstrates that the method promotes traceable reasoning about architectural decisions and supports the incorporation of ZT principles in the early stages of software design.
