Airport IT security budgets are taking off, and airports worldwide are expected to invest some $2 billion in IT and telecommunications projects annually. That's according to the Airport IT Trends Survey conducted by the Airports Council International, Airline Business magazine, and SITA, a European IT company. The study showed that IT infrastructure projects were the top investment priority, followed by security-related solutions and passenger and baggage processing. More than 96 percent of airports will face additional IT-security challenges as they roll out wireless services by 2006 and implement e-commerce and other Web services. @ The full survey costs $245 and is available at the Airline Business Web site.
