"Web site hacks are on the rise and pose a greater threat than the broad-based network attacks that have been giving IT departments fits. Whereas attacks against networks disrupt Internet service and negatively impact companies trying to do business over the Web or private networks, attacks against Web applications threaten to steal critical customer, employee, and business partner information stored in applications and databases linked to the Web.
Web hacking attacks numbered 58 in 2005, up from 16 in 2004 and 9 in 2003, according to the Web Application Security Consortium. Another 20 attacks have been reported this year against sites including open-source repository Sourceforge.net and social network MySpace.com, putting 2006 on pace to be the worst year yet.
