introduction
Introduction
  • Standard DNS
  • Security Concerns
  • DNSSEC
  • Management Implications
  • Impact to Embedded Systems
  • Conclusions
security concerns
Security Concerns
  • UDP
  • Query ID only 16 bits
    • Small search space
  • Well known ports
dnssec
DNSSEC
  • Public Key Infrastructure, e.g. SSL
  • Chain of Authority
  • Validation of DNS records
management implications
Management Implications
  • Who manages keys?
    • Root keys
    • Key rotation
    • Clock synchronization
  • Requires wide spread adoption
  • Few production implementations
impact to embedded systems
Impact to Embedded Systems
  • Embedding Challenges
    • Limited memory & storage
    • Limited CPU resources
    • Limited power
    • Expensive secure storage
  • Linux and BIND9 installed, and DNS configured. Currently configuring for DNSSEC
conclusions
Conclusions
  • DNS has security concerns
  • DNSSEC offers solutions
  • Solutions introduce new problems
