IT teams are confident in finding attacks in real time, but nearly half of the organizations that experienced a breach in the last year said it took days or weeks to detect, according to a new survey released by McAfee. The survey, conducted by research firm Vanson Bourne, consisted of 500 senior IT decision maker in January 2013, including 200 in the U.S. and 100 each in the U.K., Germany and Australia. The survey findings mirror the Verizon Data Breach Investigations report, which also found most breaches took weeks or months before they were discovered. Data was often taken in seconds or minutes. McAfee said its survey suggests that IT teams are disconnected from security professionals in the organization who are struggling to keep pace with increasingly sophisticated attacks. Here's a look at the top reasons behind the slow rate of data breach detection.
