In an attempt to bolster the security of its online infrastructure following the theft of information on over 70 million PSN accounts, Sony has appointed ex-Homeland Security official Philip Reitinger to oversee network operations.

Reitinger previously served as director of the U.S. National Cyber Security Center. Prior to that he held positions at Microsoft and the U.S. Department of Defense.

He will assume the role of senior vice president in Sony’s security division, which has been on the ropes as of late, reporting directly to general counsel Nicole Seligman. Presumably, the move will bring long-term changes in organization and approach.

“Certainly the network issue was a catalyst for the appointment,” a Sony spokesperson told Reuters. “We are looking to bolster our network security even further.”
