IBM has released a report outlining new risks to people, cargo, and worldwide flows of information, finance and transportation, the Armonk-based technology giant said today.

Based on research and interviews with more than 200 former and current government officials and policy experts, the report highlights the complexity and vulnerability of these systems and provides recommendations for the future, IBM said.

They include developing security systems that do more than just prevent attacks, but also isolate disruptions and provide quick recovery.

Another recommendation is to build technological systems that provide the right information to employees when they need it to help them do their jobs better and protect their organizations.

“Our findings indicate that a better understanding of emerging risks makes it possible to improve security and resilience without harming commercial interests,” said W. Scott Gould, vice president of public sector strategy at IBM’s Global Business Services unit, in a written statement.
