NEW YORK — Target Corp. says it has named Brad Maiorino as senior vice president, chief information security officer as the company overhauls its security department in the wake of a massive data pre-Christmas breach.

The nation's third-largest retailer, based in Minneapolis, said Tuesday that Mairorino will join the company Monday and be responsible for the company's information security and technology risk strategy.

He will help ensure the retailer and its customers are protected against internal and external information security threats.

Maiorino, who was General Motors' chief information security and information technology risk officer, will report to Bob DeRodes, who was hired as its new executive vice president and chief information officer in late April.

Before the overhaul, information security functions were split among a variety of executives.
