Chapter One — 1.1 Background to the Study

Organizations that depend on smart home automation systems are under increasing pressure to modernize, and Zero-Trust Security Architecture has emerged as one of the more promising avenues for doing so, given its demonstrated impact in related domains.

Despite this potential, many existing smart home automation systems were not originally designed with zero-trust security architecture in mind, resulting in persistent gaps in predictive maintenance that limit their overall effectiveness. This study examines how Zero-Trust Security Architecture can be applied to help close that gap.

1.2 Statement of the Problem

Existing approaches to predictive maintenance within smart home automation systems remain largely reactive and fragmented, with little systematic use of zero-trust security architecture despite its demonstrated value elsewhere. This study addresses the resulting gap by designing and evaluating a solution built specifically around zero-trust security architecture.

1.3 Objectives of the Study

1. To design and implement a zero-trust security architecture-based approach to improving predictive maintenance in smart home automation systems.
2. To evaluate the effectiveness of Zero-Trust Security Architecture in enhancing predictive maintenance within smart home automation systems.
3. To identify the key requirements and constraints relevant to deploying zero-trust security architecture in this context.
4. To assess user and stakeholder perception of the resulting system.

1.4 Research Questions

1. How can zero-trust security architecture be applied to improve predictive maintenance in smart home automation systems?
2. How effective is Zero-Trust Security Architecture at enhancing predictive maintenance within smart home automation systems?
3. What requirements and constraints are relevant to deploying zero-trust security architecture in this context?
4. How do users and stakeholders perceive the resulting system?

1.5 Significance of the Study

This study is significant to software developers and system architects seeking practical guidance on applying Zero-Trust Security Architecture within smart home automation systems. It is equally relevant to organizations that rely on these systems, offering a reference point for evaluating whether such an investment is justified, and it adds to the growing body of work on zero-trust security architecture applications in software technology / IT.

1.6 Scope of the Study

As a study of this kind, its scope is confined to designing and evaluating a zero-trust security architecture-based solution for smart home automation systems, focused specifically on predictive maintenance; broader deployment considerations fall outside this scope.
