Managing cyber-security projects of any complexity

The single biggest existential threat that's out there, I think, is cyber. 

Computer hacking really results in financial losses and hassles. The objectives of terrorist groups are more serious. That is not to say that cyber groups can't access a telephone switch in Manhattan on a day like 9/11, shut it down, and therefore cause more casualties. 

An element of virtually every national security threat and crime problem the FBI faces is cyber-based or facilitated. We face sophisticated cyber threats from state-sponsored hackers, hackers for hire, organized cyber syndicates, and terrorists.
