16 critical sectors but we're moving towards a look at essential functions which might cross sectors. so what is the function that is truly critical and how can we partner with the private sector to not only give them information on known threats but to help them anticipate threats before they get there? in terms of network defenders we need to continue to connect them as we see these threats propagate across the world. as we saw with this one the patching is very important. the reason we did not have as many effects in the united states as we did in other places of the world was due to the good work of dhs and jeanette's folks in terms of making sure they communicated quickly with the private sector and the appropriate patching was taken. it is information sharing, making sure we're sharing in the right way. it is helping them with vulnerability assessments and overall it's agreeing together what is critical and what is the best way we can protect it together.
