Speaking to The New York Times in an interview on Tuesday, Sony’s CEO Howard Stringer discussed the company’s recent security breach, and what his firm is doing to make sure such a large scale attack doesn’t happen again. Stringer argued that Sony reported the breach quickly, despite waiting nearly a week to notify its customers that hackers had stolen personal information, including credit card numbers. “We still have a lot of investigation to do to find out how this happened, but we’re not there yet,” Stringer explained. Sony’s corporate executive officer and executive vice president, Kazuo Hirai, said also noted that Sony is working to examine security on “every level of the company … from televisions to eBooks, and onwards.” Sony will create new security positions within the company, and the security employees with be tasked with setting up a “system to avoid this type of event again — putting a new system in place,” Hirai explained. Sony began restoring its PlayStation Network services in the United States last weekend after issuing a firmware update for the PlayStation 3.
