Sony appoints ex-Homeland Security chief
Philip Reitinger hired in wake of hacking attacks
Sony has hired Philip Reitinger, who was previously the director of the U.S. National Cyber Security Center, as chief information security officer.
"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."
Reitinger's career history also includes work with Microsoft and the U.S. Department of Defense.
The measure should help prevent hacker attacks like the one experienced by the company in April. Hackers accessed the data of over 77 million user accounts, while Sony Online Entertainment's website was also breaches and customer data lost.
Sony CEO Howard Stringer recently revealed that as well as being more secure, the PSN service was also more successful since the attacks.
"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."
