FYI The following message posted to the IETF RPSEC WG mailinglist may also be of interest to this groups. http://www1.ietf.org/mail-archive/working-groups/rpsec/current/msg00220.html It contains <quote original posting> a copy of the report from one of the sub-groups spawned by the US Government's initiative to examine security of the Internet among other information infrastructures. This sub-group worked on ISP BGP and DNS Security and the report is a decent articulation of the of the issues. I can't take either credit or blame for this document. Nothing new or earth-shattering, I think, but of interest.' </qoute> --Olaf
