Examples – Security in Practice From CSI/FBI Report 2002 90% detected computer security breaches within the last year 80% acknowledged financial losses 44% were willing and/or able to quantify their financial losses. These 223 respondents reported $455M in financial losses. The most serious financial losses occurred through theft of proprietary information and financial fraud: 26 respondents: $170M 25 respondents: $115M For the fifth year in a row, more respondents (74%) cited their Internet connection as a frequent point of attack than cited their internal systems as a frequent point of attack (33%). 34% reported the intrusions to law enforcement. (In 1996, only 16% acknowledged reporting intrusions to law enforcement.) Barbara Edicott-Popovsky and Deborah Frincke, CSSE592/492, U. Washington] More from CSI/FBI 2002 40% detected external penetration 40% detected denial of service attacks. 78% detected employee .
