How retailers can boost security through information sharing

Antone Gonsalves | May 16, 2014
Major U.S. retailers that have formed a group for sharing cyberthreat information will have to overcome a number of hurdles before security can be improved within the participating companies, experts say.

The kind of intelligence that would be most useful to share include actual attack scenarios, hacker techniques and methods for getting useful intelligence from the terabytes of log data collected from network computers and security systems, Patrick Harbauer, senior security consultant for Neohapsis, said.

In addition, the companies should conduct exercises in responding to a breach, Harbauer said.

"If they can get the technical people that are actually defending their systems talking to each other, then I think there would be a ton of value in that," he said.

Finally, the retailers will need to build a central repository for all the collected information, so the companies, law enforcement and federal agencies, such as the Department of Homeland Security, can access it. Some form of analytics to provide actionable intelligence from the data would also be helpful, experts say.
