Incidents reported
Note: Given the widespread use of automated attack
tools, attacks against Internet-connected systems have become so
commonplace that counts of the number of incidents reported provide
little information with regard to assessing the scope and impact of
attacks. Therefore, as of 2004, we will no longer publish the number
of incidents reported. Instead, we will be working with others in the
community to develop and report on more meaningful metrics, such as
the 2004 E-Crime Watch Survey. We
welcome ideas and proposals for other collaborations in this area.
