mr. greenfield, we all had mixed feelings., i work very closely in munich about the my grandfather. i know how perfect these guys were with things like that. of course, i can understand mr. greenfield as a survivor of a second generation that they have fear that it spreads hate and cruelty, again, on all planet. "mein kampf" was published until the war every year in several countries including america, including sweden. so it is not -- the germans made a secret out of it, and i agree as well with mr. greenfield. it is not the time if we do it yet, or half a year ago or next month. but i think for the growing youths and they have more distance to what happens in the second world war or in the holocaust at all. i think for these young people, it's important to know how a book can destroy human beings in such a way, while it was a manual for crimes, for extermination people in the world. >> mr. hess, if i may answer. i think that it is important to teach what a book can do. i don't think it is necessary to publish that book again

greenfield infrastructure when the driver is strictly security related. thank you very much for the opportunity to testify today, and i look forward to answering the committee's questions. >> thank you. now we'll hear from mr. snyder. >> gentlewoman comstock, chairman loudermilk, ranking members lipinski and beyer, thank you for the opportunity to testify today. cyber -- >> i don't think your microphone is on. sorry. >> sorry about that. chairwoman comstock, chairman lawedermilk, chairman smith, ranking members lipinski and beyer, thank you for the opportunity to testify today. the focus of today's hearing is right on point. cyber security is a shared responsibility in the public and private sectors must work together closely to counter ever evolving threats. many of the recent headlines about cyber attacks have focused on data breaches both in government and across the spectrum of industries but cyber attacks do much more than that and the incidents we see today range from basic confidence schemes to massive denial of service attacks to sophisticated and destructive intrusions into critical infrastructure systems. the attackers run the gamut and include highly crippminal enterprises, disgruntled employees
