Security Benefits

Security Benefits: "DNS security threats and mitigations
Because of the open, distributed design of the Domain Name System, and its use of the User Datagram Protocol (UDP), DNS is vulnerable to various forms of attack. Public or 'open' recursive DNS resolvers are especially at risk, since they do not restrict incoming packets to a set of allowable source IP addresses. We are mostly concerned with two common types of attacks:
Spoofing attacks leading to DNS cache poisoning. Various types of DNS spoofing and forgery exploits abound, which aim to redirect users from legitimate sites to malicious websites. These include so-called 'Kaminsky attacks', in which attackers take authoritative control of an entire DNS zone."
