Virtualization as a way to increase DNS protection against cyber threats

Abstract
Domain Name System (DNS) serves as a vital Internet component, which converts friendly domain names into their corresponding computer language IP addresses. Network service availability suffers from several cyber threats in DNS systems because Distributed Denial of Service (DDoS) attacks, spoofing, and cache poisoning expose data to unauthorized access and reduce service availability. The research examines virtualization technology, which serves as a DNS security enhancement solution to increase system resilience capacity. This work implements DNS security enhancements through virtualization elements that include threat isolation with service segmentation as well as automated recovery services with dynamic resource allocation to protect DNS systems against vulnerabilities. The framework demonstrated improvements through real-world deployment with case studies and simulations because it provided 98% improved service accessibility during DDoS attacks and decreased disaster recovery time by 60% at the same time as decreasing operational costs by 30%. The study displays extensive proof demonstrating that virtualization functions as a fundamental delivery method for fault tolerance as well as enables superior protection against preventing complex security threats and scalability features. The research findings demonstrate that DNS component protection together with fast disaster recovery capability receives vital security features from virtualization implementation. Security-conscious organizations plagued by evolving threats should adopt virtualization-based DNS service maintenance because it offers scalable and price-efficient delivery capabilities. Virtualization in DNS demonstrates itself as a strategic forward-thinking approach to create sustainable yet flexible protected online structures.
