DNS是網際網路最重要的資訊基礎服務之一,如何提供安全及可靠的服務是一件非常重要的議題。對於系統管理者,非常需要有一套工具來幫忙檢測DNS設定上的問題,減少漏洞及不適當的設定。本論文針對Authoritative DNS相關議題進行探討並了解基本需求,建置一套檢測系統,提供系統管理人員DNS設定參考及安全漏洞的提醒。經由本系統對DNS server的統計分析,可以提供管理單位對DNS安全現況進行全面性的了解。
DNS is one of the most important information infrastructure services on the Internet. How to provide secure and reliable services is a very important issue. For system administrators, a set of tools is needed to help detect problems with DNS settings, reduce vulnerabilities and inappropriate settings. This paper explores the issues related to Authoritative DNS and understands the basic needs, builds a detection system, and provides a reminder of system administrators' DNS settings and security vulnerabilities. The statistical analysis of the DNS server via this system can provide management with a comprehensive understanding of the current state of DNS security.
