Earlier this year, a cyber attack resulted in a 23-day outage of the PSN and the theft of personal details from over 77 million accounts. Sony is strengthening its online network and stepping up its security.
Sony created a new chief information security officer post, reported Reuters, and selected former US Department of Homeland Security officer Philip Reitinger for the position, who will be based in Washington.
"Certainly the network issue was a catalyst for the appointment," a Sony spokesman said. "We are looking to bolster our network security even further."
Since the security breach, Sony has added over three million new PSN users.
