I don't think it's too long and I don't think it's too short. I don't
think that 5 steps is right either and I don't think that details like
this belong in policy.

I do think that ARIN should consult a recognized security expert for
advice on this. Someone with the stature of Steve Bellovin or Bruce
Schneier for instance or someone who has credentials from IETF
security-related working groups.

99% or more of the people on this list, including me, are not qualified
to give expert opinions on this even if we have implemented security
systems in the past.
