We live today in the Cyber Era. Each individual one sees on the street carries more computing and communications power than entire cities had in the past. Everything is faster, more accurate, and more flexible. Simultaneously, we have faced numerous malware intrusions, seen nations attacked, and our own infrastructure assaulted. Given this plethora of threats, how do we properly plan? The military and security communities have for years used a paradigm to determine against which of a large number of possible threats they should plan. They determine the most dangerous and most likely threats, which are seldom the same. A similar process can help us thoughtfully address cyber issues.
We face a scenario that fits the part of the most dangerous threat; we must also face and prepare for a most likely scenario that is unique. This threat will involve the merger of the growing cyber-crime capability with the terrorists' realization that the cyber realm is theirs for exploitation and that joining with cyber criminals will be the path to their goal. This second threat falls into the realm of homeland security.
