A growing shortage in security staffing and skills is creating a seller's market for security professionals--and could drive new thinking in hiring, experts said at the (ISC)2 World Congress 2012 and ASIS International 2012 in Philadelphia.

Here at the Career Pavilion at the co-resident annual conferences of two of the world's largest security professionals' associations, job hunters are finding a target-rich environment for workers with advanced skills. The industry will need to add nearly 2 million jobs over the next three years in order to keep up with demand, according to industry figures.

The growing gap between supply and demand is creating problems for many enterprises and may cause some to cast a wider net in search of talent, speakers at the event said.
