Are Your DNS Servers Vulnerable to Cache Poisoning Attacks?

Denise Dubie writes on NetworkWorld:

More than half of Internet name servers today allow requests that leave networks vulnerable to cache poisoning and distributed denial of service attacks -- a fact that has not improved over the past year.

The finding is part of the third annual survey of the Internet’s domain name servers released this week by The Measurement Factory, which conducted the survey for DNS management appliance maker Infoblox. The survey is based on a sample that included 5% of the IPv4 address space -- nearly 80 million devices -- and works to reveal configuration errors that compromise network security and availability.
