Overview Why is ESnet implementing DNSSEC? What is required? UPDATED How will DNSSEC be implemented in ESnet? NIST SP800-81 Implementation recommendations http://csrc.nist.gov/publications/nistpubs/800-81/SP800-81.pdf NIST SP800-53 Rev. 1 FISMA Requirements http://csrc.nist.gov/publications/nistpubs/800-53-Rev1/800-53-rev1-final-clean-sz.pdf
What is Required? OMB mandate in NIST SP800-53 Rev. 1 TSIG for zone transfers Has operational advantages beyond security enhancement Firewall rules may cause issues Required by SC-8 (Not obvious!) Signed data only required by medium and high impact systems Seems silly if it is not a general requirement In SC-20 through SC22
Where is ESnet ? TSIG authentication of all zone transfers Partly implemented Most larger sites are using it Some sites have old software lacking support Some sites have firewall rules which complicate issues Signing of all forward zones Test server is in service and working As expected, key management IS a pain
Status of Implementation TSIG is currently implemented for several sites Mandatory for new sites PGP used for key distribution Signed data Still not running on production servers Will be in a few weeks Our DNS management software does not support DNSSEC today (coming soon!) No implementation problems on BIND systems Still worried about key distribution and roll-over Still targeting full production by mid-2008
Summary Progress has been made Requirements are now known None (for ESnet) Hope for full implementation of TSIG by the end of the year Signed zones by the end of the year (ESnet zones) Still waiting on a final resolution to NSEC issue Almost certainly NSEC3 Will not ask sites to sign zones until resolved That does not mean that you can't sign
