Access Management In Smart Ecosystems: Pathways To Achieving Environmental Sustainability And Green SDGS

Abstract

Smart Connected Ecosystems (SCEs), fusing large-scale IoT implementations with cloud and edge centers, do offer a very large and moving attack surface and swiftly changing cross-domain access requests. Therefore, these real-time requirements, as well as the advancement of Green SDGs, are not satisfied by the conventional discretionary, mandatory, static role models. This article systematically benchmarks thirteen traditional and hybrid paradigms; DAC, MAC, RBAC, ABAC, RAdAC, RABAC, FBAC, TBAC, and task-centric schemesagainst a set of seven operational metrics: flexibility, scalability, administrative complexity, decision latency, reliability, dynamicity, and quality of service. The results found with composite frameworks-in which RBAC deterministic hierarchies are combined with ABAC contextual attributes and RAdAC continuous-risk scoring-offer the best balance in terms of security–sustainability trade-off by reducing unnecessary activations and overhead in the cloud, energy consumption, and e-waste. The study concludes that adaptive, sustainability‑aware access control must underpin future SCEs; emerging risk‑ and fuzzy‑logic models should be refined toward attribute minimisation and federated policy orchestration to secure low‑carbon, resilient digital infrastructure.
