域名系统及其安全性 [英] Domain Name System and its Security

问题描述

这里的每个人都知道什么是DNS及其作用.

我想知道与DNS相关的安全问题

使用DNS的威胁如下.
DNS欺骗
DNS缓存中毒
DNS IP黑客攻击

但是，在当今这个高度安全的世界中出现这些事情还是
DNS仍然容易受到这些威胁的影响吗?

如果容易受到攻击，我们可以使用密码技术来避免或减少它们吗?...

Everyone here knows what is DNS and what does it do.

I want to know abour security issues related with DNS

Threats of using DNS are as follows..
DNS Spoofing
DNS Cache poisoning
DNS IP Hacking

But do these things present in today''s much secured world or
is DNS still vulnerable to these threats,

If it vulnerable can we use cryptography techniques to avoid or reduce them...

推荐答案

该主题太大了，无法在简短的答案中进行回顾，我认为，太复杂，无法对此做出简短的判断.但是，简而言之:是的，确实存在威胁，对的，加密方法可以大大降低成功进行DNS相关攻击的可能性.

首先，您是否阅读了下面的文章参考?请参阅:
http://en.wikipedia.org/wiki/DNS_spoofing [ http://en.wikipedia.org/wiki/Pharming [ http://en.wikipedia.org/wiki/DNS_hijacking [

This topic it too big to review it in a short answer and, I think, too complex to give one short judgment on it. However, in a nutshell: yes, the threat does exist and, you are right, cryptographic approach can greatly reduce the probability of successful DNS-related attacks.

To start with, did you read the articles references below? Please see:
