Cybersecurity is an issue of increasing concern since the events of September 11
Many questions have been raised concerning the security of the Internet and the rest of US’s
information infrastructure. This paper begins to examine the issue by analyzing the Internet’s
autonomous system (AS) map. Using the AS map, malicious infections are simulated and
different defense strategies are considered in a cost benefit framework. The results show that
protecting the most connected nodes provides significant gains in security and that after the small
minority of the most connected nodes are protected there are diminishing returns for further
protection. Although if parts of the small minority of the most connected firm are not protected,
such as non-US firms, protection levels are significantly decrea
