Target CFO Says Retailer Increasing Cybersecurity After Breach

(Washington, DC) -- Target chief financial officer John Mulligan says the retail giant is making steps to protect its computer system after last year's massive data breach. Mulligan testified Wednesday before a U.S. Senate committee looking into the breach. Senator Richard Blumenthal of Connecticut cited a report showing Target missed Amultiple warningsA that could have prevented the issue. Mulligan said Target has separated key parts of its computer network, increased investments in malware protection and added another layer of authentication for those accessing the computers.
