Such caution is also shared by many. Symantec's study indicated that 54% of the respondents from Hong Kong view mobility as somewhat to extremely challenging and 37% identified mobile devices as one of the top three IT risks.

This concern is understandable with various reports indicating malware--particularly mobile malware--continue to grow. Juniper Network's 2011 Mobile Threat Report indicated mobile malware across all device platform, increased by 155% last year. The majority (63%) is spyware, which could be stealing data from corporate smartphones without the users' knowledge.

"To enable security and protection of corporate data, remote lock and wipe capabilities are critical," said Peter Smith, director of Wavelength Consulting, a mobile strategy consulting firm. "Never allow a device to access corporate information without [enabling] remote lock and wipe."

The former CIO of local mobile operator CSL, Smith noted having access to monitor and remotely wipe off data should be a policy that applies to all devices that have access to the corporate internal system, regardless they are corporate-owned or under BYOD policy.
