Serious data breaches take months to spot, analysis finds

More than six out of ten organisations hit by data breaches take longer than three months to notice what has happened with a few not uncovering attacks for years, a comprehensive analysis of global incidents by security firm Trustwave has found.

During 2012, this meant that the average time to discover a data breach for the 450 attacks looked at was 210 days, 35 more than for 2011, the company reported in its 2013 Global Security Report (publically released on 20 February).
