On April 22, we celebrate Earth Day, a day intended to reflect appreciation for the Earth's natural environment. You are probably thinking, “How can we apply the concept of ecosystems to the man-made domain of cyberspace?” A recently published Department of Homeland Security (DHS) whitepaper, “Enabling Distributed Security in Cyberspace,” describes the need for a healthy and resilient cyber ecosystem. Similar to natural ecosystems, cyber ecosystems have a variety of diverse participants, including private firms, non-profits, governments, individuals, processes, and cyber devices. These cyber species interact at machine speed and can have a positive and a negative impact on the cyber ecosystem.
