ICDCIT 2004 From Vulnerabilities to Losses Growing business losses due to vulnerabilities in distributed systems Identity theft in 2003 – expected loss of $220 bln worldwide ; 300%(!) annual growth rate [csoonline.com, 5/23/03] Computer virus attacks in 2003 – estimated loss of $55 bln worldwide [news.zdnet.com, 1/16/04] Vulnerabilities occur in: Hardware / Networks / Operating Systems / DB systems / Applications Loss chain Dormant vulnerabilities enable threats against systems Potential threats can materialize as (actual) attacks Successful attacks result in security breaches Security breaches cause losses ICDCIT 2004 Vulnerabilities and Threats Vulnerabilities and threats start the loss chain Best to deal with them first Deal with vulnerabilities Gather in metabases and notification systems info on vulnerabilities and security incidents, then disseminate it Example vulnerability and incident metabases CVE (Mitre), ICAT .
