Ranking network security breaches
IN a 2004 CSI/FBI Computer Crime and Security Survey, security practitioners from major US corporations, financial, medical institutions and government agencies participated in a recent CSI/FBI Computer Crime and Security Survey. The declining trend year-on-year of total loss is a good sign of cyber security awareness in the US.
For 2004, in terms of cost to business, the denial-of-service attack has taken over theft of proprietary company information from the prior survey. Virus-related breaches rank the most costly. Here’s a quick rundown of the 2004 survey result, in terms of dollar amount of losses (cost to business per year) by security breach type:
- Viruses — 55 million dollars
- Denial-of-service attacks — 26 million dollars
- Data theft — 11.5 million dollars
- Insider Net abuse — 10.6 million dollars
- Abuse of wireless network — 10.2 million dollars
