DNS Cache Poisoning: Definition and Prevention

The Internet would grind to a halt ? would not be possible ? without a Domain Name System (DNS). As you?ll see in this paper, the proper operation of DNS is fundamental to the maintenance and distribution of the addresses for the vast number of nodes around the globe. So it would be too much to hope for crackers (malicious hackers) to ignore DNS as they continuously look for new ways to circumvent your security.

There are several facets to DNS security. In this paper we focus on one of the most dangerous types of attack ? DNS cache poisoning. To provide a complete picture of this threat, we?ll explore how DNS works, two ways crackers facilitate cache poisoning, what impact this type of attack can have on your organization, and steps you can take to protect your information assets.
