Sony has invested in a Cyber Security expert with the hope of strengthining its operations to avoid more hacking debacles.

Philip Reitinger has been hired to fill a newly created role overseeing Sony’s security strategy.

In a statement, Sony said Reitinger will “oversee information security, privacy and internet safety across the company, coordinating closely with key headquarters groups and working in partnership with the information security community to bring the best ideas and approaches to Sony.”

The company is looking towards Reitinger’s experience at Homeland security, the US Department of Defense and Microsoft to strengthen its PlayStation Network security after it succumbed to one of the largest scale hacks to date, with the hacking of its PSN network resulting in the information of 77 million accounts being compromised.

“Certainly the network issue was a catalyst for the appointment,” a Sony spokesman told Reuters.

“We are looking to bolster our network security even further.”

Sony’s CEO Howard Stringer has assured the network today is more secure, and has been more successful since the attack with an additional 3 million customers.

“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.”

Reitinger’s appointment is effective immediately.
