• 91% of attackers were organized crime
• 74% of attacks by malicious outsiders
• 67% of vulnerabilities due to system defects
• 32% implicated business partners

The report must be particularly disturbing to endpoint DLP vendors focused on preventing data loss by trusted insiders on  PCs (  99.6% of data was breached by  attackers attacking servers…. )

My experience with clients in the past 5 years in the data loss/extrusion prevention business has been focused on discovering internal security vulnerabilities and implementing cost-effective security countermeasures.  Our findings (summarized in our Business Threat Modeling white paper) were based on analyzing empirical data of 167 data loss events points a finger at software defects as a key data loss vulnerability. The Verizon business study appears to suggest that the situation has only gotten much worse – i.e. data breachs are rising as software quality is declining.

A conservative estimate in our research showed that 49% of the events exploited software defects as shown in the below table. Theoretically we can mitigate half of the risk by removing software defects in existing applications. The question, which we  answer in the white paper is how.

The Carnegie Mellon Software Engineering Institute (SEI) reports that 90 percent of all software vulnerabilities are due to well-known defect types (for example using a hard coded server password or writing temporary work files with world read privileges). All of the SANS Top 20 Internet Security vulnerabilities are the result of “poor coding, testing and sloppy software engineering
