Tiivistelmä
This research examines the effectiveness of Software-Defined Networking (SDN)-based Network Access Control (NAC) solutions in enhancing network security, performance, scalability, and adaptability. Combining qualitative and quantitative approaches, the study involves an extensive literature review, the design of an experimental network environment, and data collection through both real-world simulations and expert interviews.
Key performance indicators such as latency, throughput, and threat detection rates are analyzed using statistical methods, while thematic analysis is applied to the qualitative data. The findings are validated through simulation and real-world case studies, ensuring the reliability and generalizability of the results. The research identifies significant advantages of SDN-based NAC, including dynamic policy enforcement, centralized control, and improved visibility, while also addressing potential challenges such as performance overhead and scalability. The study concludes with recommendations for optimizing SDN-based NAC implementations, contributing valuable insights for enhancing network security in diverse and evolving network environments.
