  1. RASD Rapid Adaptive Secure DNS Matthew Weaver Jeremy Witmer Dr. Chow, Advising CS 622 – Fall 2007

  2. Overview • We designed and implemented a system to secure DNS traffic on a local network RASD - Weaver/Witmer - CS622

  3. System Design Goals • Create trusted channels for name record information exchange • Rapid server-side push updates to cached name records RASD - Weaver/Witmer - CS622

  4. Data Exchange Format • DNS traffic is UDP • Keep UDP on the client • Client/Server communication is XML over SSL RASD - Weaver/Witmer - CS622

  5. Client Software • Listen and respond to local DNS queries, with caching • Listen for server-pushed name record updates RASD - Weaver/Witmer - CS622

  6. Server Software • Listen for client DNS queries and respond, with caching • Wait for name record updates, and push to registered clients RASD - Weaver/Witmer - CS622

  7. Prototype Results • <to be added, we’re not quite there yet> RASD - Weaver/Witmer - CS622

  8. Further Research • Extended DNS handling • RASD Server discovery • Automatic Client Installation • SCOLD Environment testing • Standardized entry caching RASD - Weaver/Witmer - CS622
