Academics have been hard at work studying information security. Most fields aren't as replete with hackers as information security, though, and their contributions are felt much more strongly in the private sector than in academia. The differing motives and professional cultures of the two groups act as barriers to direct collaboration, noted CypherCon presenter Anita Nikolich.

The expanding world of Internet commerce likely will generate a corresponding expansion of data breaches, resulting in more e-commerce businesses becoming the targets of consumer class action lawsuits. Breach litigation has become more prevalent as a result of a perceptible legal trend favoring consumers. Courts have tended to allow lawsuits based on a lower threshold for establishing injury.

A significant percentage of IT systems are cloud-based, according to a recent survey. The cloud is a key enabler for emerging technology, suggests the CompTIA poll, which was conducted last month.
