Cybersecurity in Library Systems Protecting Patron Data and Digital Collections from Cyber Threats and Breaches

This paper examines cybersecurity challenges in contemporary library systems and proposes strategies to safeguard patron data and digital collections. Through qualitative analysis of recent literature, standards, and documented cyber incidents, it identifies prevailing threats such as ransomware, phishing, denial-of-service attacks, insider misuse, and third-party vulnerabilities. The study evaluates weaknesses in Library Information Systems, highlights the ethical imperative of patron privacy, and reviews frameworks including NIST-CSF and ISO/IEC 27001. It further explores emerging solutions—AI-based anomaly detection, blockchain-secured access, and privacy-by-design models—offering a comprehensive framework to strengthen resilience in academic and public libraries and inform policy, training, and technology investment decisions nationally.
