Mobile phone calls as a business risk

Mobile phone technology is under attack, leaving users and businesses vulnerable. Much has been written on the data risk to businesses from mobile phones but it's only recently that the risk of voice call interception has hit the headlines. Now businesses have to face up to the challenge of securing corporate information without unduly restricting the use of this essential business tool. Traditionally, the role of network security has focused largely on protecting data, computers and the perimeter of an organisation's IT infrastructure, with the security of voice calls being under-resourced, overlooked or assumed safe. Now, with GSM security broken, and more people than ever before using mobiles to discuss confidential and sensitive information, suffering a major data breach due to mobile phone interception is a risk no CIO can afford to ignore, says Simon Bransfield-Garth of Cellcrypt.
