The goal of NCSS is to produce reliable national and industry-level estimates of the prevalence of computer security incidents (such as denial of service attacks, fraud, or theft of information) against businesses and the resulting losses incurred by businesses. The first national survey of thousands of businesses is being conducted in 2006. It is cosponsored by the Bureau of Justice Statistics and the National Cyber Security Division (NCSD) of the U.S. Department of Homeland Security. The RAND Corporation is the data collection agent. The NCSS collects data on - - the nature and extent of computer security incidents - monetary costs and other consequences of these incidents - incident details such as types of offenders and reporting to authorities - computer security measures used by companies.
