Using Virtualization to Secure Mobile Device Designs

Mobile devices are increasingly coming under attack from malicious applications. As more complex operating systems (OS), such as Symbian, Windows Mobile, and Linux are used in handsets, providing security updates and identifying new vulnerabilities has become more complicated. Addition ally, frequent patching and rewriting of code to keep one step ahead of hackers undermines the utility and longevity of legacy software. What developers really need is an environment that is inherently safe from attack and provides the appropriate level of security for all code running in the target device. Secure, segregated areas for critical code must be combined with secure communications in order to provide protection for mobile devices.
