Even with a qualified SHOULD on the overall set, data segment protection is still a MAY. What it changes is the SHOULDs on the RST and SYN to MUSTs, to say that you shouldn't implement one or the other as desired *if* you decide to implement the set. ... > So, the game plan moving forward is, to generate the AS and revisit the > mitigation strengths.

I know - that was one of the set discussed. OK, so here's what I'm specifically asking: 1) is the AS above reasonable? 2) regarding the RST/SYN/data components: - are the MUST/MUST/MAY above reasonable? - Or should they be SHOULD/SHOULD/MAY? - or something else Joe
