DNSSEC与DNS安全防范研究

摘要

DNS has become an important basic service to Internet,but it exists serious security loopholes.It has caused great damage to the Internet due to network attacks aimed at security loopholes in recent years.This paper introduced the principles of DNS and the risks it faces in brief,analysed how to promote DNS Security,and studied a safe solution to DNS security based on DNSSEC。%DNS已成为互联网重要的基础服务,但它存在着严重的安全漏洞,近年来针对这些安全漏洞的DNS网络攻击给互联网带来了巨大的损失。本文介绍了DNS的工作原理,阐述了其面临的安全风险,对提高DNS系统安全性作了分析,并就基于DNSSEC的DNS安全解决方法进行了探讨。
