Strengthening Cybersecurity for Critical Infrastructure Through Zero-Trust Security Models
Keywords:
Zero-Trust Security, cybersecurity, critical infrastructure, access control, insider threats, network securityAbstract
Critical infrastructure sectors such as energy, transportation, and healthcare are increasingly targeted by sophisticated cyber threats. Traditional security paradigms, reliant on perimeter-based defenses, have proven inadequate in mitigating modern cybersecurity challenges. Zero-Trust Security (ZTS) has emerged as a transformative paradigm, emphasizing the principle of "never trust, always verify." This paper explores the role of ZTS in reinforcing cybersecurity protocols for critical infrastructure, analyzing its fundamental principles, implementation challenges, and benefits. A review of recent literature highlights the efficacy of ZTS in preventing unauthorized access, minimizing insider threats, and enhancing overall security resilience. Quantitative data and case studies substantiate the paradigm's capacity to adapt to evolving threat landscapes.
