Abstract
<div class="section abstract"><div class="htmlview paragraph">Zero trust (ZT) is an emerging initiative that focuses on securely providing
access to resources based on defined policies. The core tenet of ZT is “never
trust, always verify”, meaning that even within trusted zones of operation,
resource access must be explicitly granted. ZT has proven effective in improving
the security posture in domains such as information technology infrastructure;
however, additional research and development is needed to define and apply zero
trust principles to cyber-physical system domains. To work toward this
objective, we have identified an initial set of ZT architectural patterns
targeted specifically at cyber-physical systems. We created ZT architecture
patterns in the Architecture Analysis and Design Language (AADL), a modeling
language that enables engineers to describe the key elements of embedded system
architectures using a well-defined semantics. The patterns are implemented as a
library of ZT components that can be made available to system engineers.
Utilizing AADL capabilities, engineers can model a system in AADL and apply one
or more of these ZT patterns to improve the system security posture based on
specific system requirements. To demonstrate our approach, we apply the ZT
patterns to an unmanned aerial vehicle surveillance application. The resulting
design provides inherent protection from a variety of attacks affecting system
confidentiality, integrity, and availability.</div></div>
