That is the finding of a new biannual report from the SANS Institute, a training organization for computer security professionals, whose senior staff weighed two sets of data that have not been rigorously compared to date: data on the most common attacks hitting corporate networks and data on which vulnerabilities are most prevalent on company networks.  Read the full story [nytimes.com]   Read the full report [sans.org]
