TOKYO — Sony has hired former U.S. Homeland Security deputy undersecretary Philip Reitinger as its security chief.

The position was newly created by the company after a series of security hacks starting last April exposed the data of nearly 100 million subscribers to its online game and music services.

In addition to serving as chief information security officer, Reitinger will be senior vice president, reporting to executive veep Nicole Seligman.

At Homeland Security Reitinger was deputy secretary for the National Protection and Programs Directorate and director of the National Cybersecurity Center, charged with orchestrating government cyber security efforts, though he also worked with Sony in investigating the April hacks. Prior to his government appointment, he was Microsoft’s top security exec from 2003 to 2009.

Following the hacks, Sony’s PlayStation Network and Qriocity music services went off-line but service has since been fully restored in all territories. Sony topper Howard Stringer has said PlayStation Network has added 3 million new users since the breaches.
