本文主要研究內容,在於設計並實作完成一套以DNS 本體為基礎,嘗試發展出一套結合網域名稱系統(DNS)查詢分析以及IEEE 802.1x認證系統為本的網路異常偵測與根除入侵者的網路管理輔助系統。 In this paper, we design and implement a DNS-based network anomalous detection and intrusion eradication scheme, combining the DNS-based anomaly detection and IEEE 802.1x-based authentication scheme for supporting the intrusion eradicating process.
