Document: draft-farrell-perpass-attack-05 Reviewer: Scott Brim Review Date: 2014-02-01 IETF LC End Date: 2013-12-31 IESG Telechat date: 2014-02-06 Summary: This draft is ready for publication as a BCP. Major issues: Minor issues: Nits/editorial comments: Two comments: First, there are good arguments for publication as Informational , but since it incrementally adds to BCP 72, it should be incorporated there, so BCP is slightly better. Second, the only significant difference from -04 was the removal of "and be prepared to justify their decisions". There was a lot of discussion that led to this, and some concern that the statement on architectural considerations is not strongly enough worded without it. However, see the previous paragraph (both paragraphs are below). I believe that these two paragraphs, taken together, do what is desired. Those developing IETF specifications need to be able to describe how they have considered PM, and, if the attack is relevant to the work to be published, be able to justify related design decisions. This does not mean a new "pervasive monitoring considerations" section is needed in IETF documentation. It means that, if asked, there needs to be a good answer to the question "is pervasive monitoring relevant to this work and if so how has it been considered?" In particular, architectural decisions, including which existing technology is re-used, may significantly impact the vulnerability of a protocol to PM. Those developing IETF specifications therefore need to consider mitigating PM when making these architectural decisions. Getting adequate, early review of architectural decisions including whether appropriate mitigation of PM can be made is important. Revisiting these architectural decisions late in the process is very costly. Scott
