PlayStation Network is more secure than ever, says Sony

Sony CEO Howard Stringer has said that the firm has bounced back from this year's PlayStation Network security breach.

Speaking at the IFA conference in Berlin, the executive claimed that PSN is "better and more secure than ever", CNET reports.

Stringer also announced that the service has gained an additional 3 million subscribers since the hack, and sales figures from the PlayStation Store have increased relative to pre-attack levels.

"I'm pleased to tell you that the PSN is more secure and better than ever," Stringer said. "We are aggressively expanding its content. We have more than 3 million new customers since the network came back online, and sales are exceeding what we had before the cyber attacks."

PlayStation Network went offline in April due to a severe breach that led to personal details and credit card information being stolen. Full access to the service was restored the following month.

Sony president of network entertainment Tim Schaaff described the incident as a "great learning experience", but added that he "would not like to do it again".
