WSEC DNS


WSEC DNS is a novel query algorithm devised to protect recursive DNS (RDNS) resolvers from cache poisoning attacks, including Kaminsky's attack.

  • Implementation of WSEC DNS based on PowerDNS v3.1.7 [download]
    • NOTE : our implementation of WSEC DNS is only a proof-of-concept. The secure cache update policies for root and TLD name servers are not implemented (see Section 3.5 of our DSN-DCCS paper). Also, not all the policies for handling configuration corner cases are implemented.
