The accelerated pace of the cyberspace evolution over the last 20 years has introduced a national as well as a global reliance on a manmade infrastructure for economic prosperity, military power, and societal communications all of which affect the United States' Strategic Culture. Cyberspace crosses state boundaries, globally connecting societies, critical infrastructures and commerce, thus enabling unprecedented freedom of communication and access to information and trade. There is now an insatiable appetite for convenience of communication with the ease of use and desire for global reach. This increasing demand creates an environment vulnerable to exploitation and attacks. While both the government and the private sector recognize the threats posed through cyberspace and the risk of doing nothing, the current U.S. strategic culture does not align well to affect required change to secure U.S. interests in cyberspace. To effectively develop and implement a holistic cyberspace strategy, one must understand the cyberspace evolution’s impact on the strategic culture. This paper will analyze the current U.S. strategic culture, the impact of the cyberspace evolution on the strategic culture and provide cyberspace security policy and strategy recommendations.
