BlackBerry Ltd has named David Kleidermacher as its chief security officer.

Kleidermacher was previously chief technology officer at embedded software maker Green Hills Software, where he spent more than two decades, reported Fox Business. Green Hills' technologies power systems as diverse as medical devices and aircraft made by the likes of Boeing Co, Airbus Group NV and Lockheed Martin Corp.

At Blackberry, he replaces Scott Totzke, who left the company last summer and is now the senior vice president of device and enterprise security at Chinese telecom equipment company Huawei Technologies Co., said Fox Business. 

According to the Fox Business report, Kleidermacher will oversee a number of key initiatives, including security-specific research and product development, and the company's product certification and approval program.

"David's knowledge of securing the Internet of Things and embedded systems will be invaluable as we execute on our strategy," BlackBerry Chief Executive Officer John Chen said in a statement.
