“While we are still in the process of an ongoing investigation, we recognize that the information security environment is evolving rapidly,” said Chief Executive Officer Gregg Steinhafel. The new chief information officer will be a key player in the redesigning of Target Corporation (NYSE:TGT)’s information-security and compliance operations, Steinhafel elaborated.
