Abstract

While cooperative DNS resolver systems, such as CoDNS, have demonstrated improved
reliability and performance over standard approaches, their security has been weaker,
since any corruption or misbehavior of a single resolver can easily propagate throughout
the system.

We address this weakness in a new system called ConfiDNS, which augments the cooperative
lookup process with configurable policies that utilize multi-site agreement and per-site
lookup histories.  Not only does ConfiDNS provide better security than cooperative
approaches, but for up to 99.8% of unique lookups, ConfiDNS exceeds the security of
standard DNS resolvers. ConfiDNS provides these benefits while retaining the other
benefits of CoDNS, such as incremental deployability, higher reliability, and improved
performance, in some cases faster than CoDNS.  We discuss the implementation of ConfiDNS
and the challenges of running a distributed agreement protocol in an environment where
DNS-based redirection is is used to facilitate load-balancing and localized content
distribution.
