A Smart Proactive Forensic Meta-Model for Smart Homes in Saudi Arabia Using Metamodeling Approaches

The increasing adoption of smart home technologies introduces significant cybersecurity and forensic challenges. This necessitates a shift from traditional reactive digital forensics to a more proactive approach to safeguarding these environments. This research is situated within Saudi Arabia’s ambitious digital transformation, as outlined in Vision 2030, which promotes the development of smart cities and homes. The unique technological landscape and national initiatives in Saudi Arabia require tailored cybersecurity solutions. Existing models are often too theoretical, generic, or overly specialized, lacking practical validation and comprehensive integration for modern IoT ecosystems. There is a pronounced lack of a scalable, validated framework designed explicitly for proactive digital forensic readiness in smart homes. The study employs a mixed-methodology approach, combining a PRISMA systematic literature review with Design Science Research (DSR) to develop and validate the Smart Proactive Forensic Metamodel for Smart Homes (SPFMSH). The developed SPFMSH was tested against realistic cyberattack scenarios, including unauthorized access and intrusion, data exfiltration, and device hijacking by ransomware. In each scenario, the model demonstrated its capability to proactively detect threats, automatically preserve forensic evidence, and provide structured investigative timelines. This validation proved its effectiveness in transforming security incidents into forensically sound investigations within the Saudi smart home context. SPFMSH delivers a practical, holistic framework that addresses the limitations of previous models, moving beyond theory to offer an implementable solution. Its development is a significant step towards enhancing national cybersecurity resilience and supporting the secure adoption of smart home technologies in alignment with Saudi Vision 2030.
