Dave Dittrich has been involved in investigating and countering computer crimes going back to the late 1990s, first in a support role, then network security operations, consulting, and applied computer security research. He coined the term "Active Response Continuum" in 2005 to describe the socio-technical hurdles defenders must overcome and to guide researchers and security operators in bridging the gaps between skill levels of responders and between private actors and law enforcement, all the while acting in ways that maintain the trust and confidence of the general public. Dave has a long list of publications and has presented extensively at invited talks, panels, and conferences around the globe.
