City lights: Securing critical infrastructure

George V. Hulme | March 5, 2013
During the 2007 housing crisis, Columbus, Ohio--like most municipalities--faced significant tax shortfalls and revenue constraints.

Another strategy helped consolidate security efforts and shift costs so it was easier to fund convergence efforts, Calero said. By outsourcing operational IT security functions to a services provider, annual costs were cut from $380,000 to $95,000, and the relationship established the foundation for adding physical security information management (PSIM) to the current security information event management capabilities.

"Encompassing both IT and physical security event correlation will lead to increased situational awareness," Calero said.

While the city has come a long way, Calero said, he also believes there is much more to be done, including further integrating video and access systems, adding more facilities, and exploring industrial control systems monitoring with the outsourced security service provider.

"We are not finished yet. Not by a long shot. But we are moving forward and leveraging wins both big and small."
