Lucrative opportunities emerge in data security

With increasingly frequent reports of big companies just as Google, DuPont, GE, and Johnson & Johnson being targeted by hackers, the "infosec" career field is growing "as fast as online computing is expanding," said Weaver, 33.

As new technologies spread, so do the security threats, said David Foote, CEO and co-founder of Foote Partners L.L.C., in Vero Beach, Fla., which conducts independent technology on information innovation jobs.

In 2007, spending on security as a percentage of operational IT spending by businesses was 7.2 percent, Foote said. By 2010, it had increased to 13.5 percent.
