or are "Cyberspace" and "Cyber Space" the same? Towards better understanding Cybersecurity: or are "Cyberspace" and "Cyber Space" the same? Stuart Madnick1, Nazli Choucri1, Steven Camina1, Wei Lee Woon2 1Massachusetts Institute of Technology; 2Masdar Institute of Science and Technology Many technological and technical challenges affect cybersecurity. However, human actions (or inactions) can sometimes pose the largest risks. One problem: we often don’t “see the world” the same way. For a start, what does “cybersecurity” actually mean? How is it related to “cyberthreat,” “cybercrime,” etc.? Dictionaries, glossaries and other sources tell you what words/phrases are supposed to mean, but may not accurately reflect what they actually mean, or how they are used in practice. Introduction “Cyberspace” “Cyber Space” To demonstrate this point, consider the case of “cyberspace” vs “cyber space” It might be assumed that “cyberspace” and “cyber space” are essentially the same word, with just a minor variation in punctuation. But is this necessarily true? Objectives We have developed techniques for automatically generating taxonomies for selected “seed terms” using large document repositories, such as Compendex and Inspec, based on co-occurrence. These taxonomies reflect relationship amongst terms, and help to elucidate broad usage patterns. We can use this to test the previous assumption - if “cyberspace” and “cyber space” are indeed the same, we expect roughly similar taxonomies. Method Discussion The taxonomies above are very different. Possible reasons: Authors of papers in different fields use different terms Usage of terms vary across geographical regions Different words may have been favored in different time periods Lots of scope for future research, including: Detailed study of reasons behind observed differences (we do know some) Different “seed terms” (e.g., “cyberthreat”) Alternative text databases/source types Different taxonomy generation algorithms “Face validity” via consultation with domain experts Acknowledgements: This work was supported, in part, by the MIT-Harvard “Explorations in Cyber International Relations” (ECIR) Project, which is funded by the Office of Naval Research under award number N00014-09-1-0597.
