A Multi-Layered Cybersecurity Model for ERP Systems Supporting National Critical Infrastructure: Threats, Challenges, and Solutions
Chandrasekhar Atakari · International Journal of Emerging Trends in Computer Science and Information Technology · 2024
Enterprise resources Planning (ERP) systems have become essential infrastructural pillars of transactions in both governmental and commercial industries, but particularly among components of the national critical infrastructure (NCI), which entail energy, defence, transportation, and healthcare. ERP digitalization and its combination with the IoT, cloud, and AI technology have only increased their exposure to advanced cyber threats. The following paper would suggest a multi-tier cybersecurity framework in NCI domains, which would target ERP-based systems. The model also combines preventive, detective, and corrective controls at the physical, network, application, and data layers. Due to the comprehensive analysis, it categorizes the threat vectors, looks at the legacy ERP security challenges, and gives the solutions utilizing Zero Trust Architecture, anomaly detection using AI, blockchain integrity to ensure access security, and role-based access controls. We test the model within simulated environments of attacks and represent the results, showing noticeable advancements in threat mitigation. The paper concludes by stating that there should be constant surveillance and security measures that are dynamically modified. This multilayered strategy will guarantee the system and business sustainability, operational resilience, and international cybersecurity regulations
