Zero-Trust Architecture Adoption in Resource-Constrained Universities

Abstract	Universities operate unusually complex digital ecosystems containing student information systems, learning-management platforms, research infrastructure, cloud services, administrative applications, personally owned devices, Internet of Things endpoints, laboratories, guest networks, remote users, and geographically distributed institutional resources. Conventional perimeter-oriented security becomes increasingly difficult to sustain in such environments because legitimate users and protected resources routinely operate outside a single trusted network boundary. The National Institute of Standards and Technology defines zero trust as a cybersecurity paradigm that removes implicit trust based solely on network location and places protection around users, assets, and resources through continuous and context-sensitive authorization. Although Zero-Trust Architecture offers a compelling security model for universities, institutions with limited cybersecurity staffing, aging infrastructure, decentralized administration, and restricted technology budgets cannot realistically replace their entire security stack simultaneously. This study develops a phased, resource-sensitive framework for Zero-Trust Architecture adoption in universities operating under financial and technical constraints. The proposed approach integrates identity and access management, multifactor authentication, device posture, data classification, application-level authorization, network segmentation, visibility, analytics, governance, and legacy-system accommodation. The methodological framework is informed by NIST SP 800-207, NIST's finalized SP 1800-35 implementation guide, CISA's Zero Trust Maturity Model Version 2.0, and higher-education-specific implementation experience. NIST's 2025 implementation guide demonstrates that organizations can migrate incrementally toward zero trust while integrating legacy and cloud environments rather than requiring complete infrastructure replacement at the outset. A transparent simulation prioritizes six adoption domains for a resource-constrained university, with identity and access management receiving the highest illustrative implementation priority score of 94, followed by data protection at 89 and device security at 84. The numerical values are methodological simulations rather than observations from actual institutions. The study concludes that financially constrained universities should approach zero trust as a maturity journey rather than a single procurement project, beginning with high-value identity, data, and device controls before progressing toward finer network segmentation, application-level policy enforcement, advanced analytics, automation, and continuous authorization.
