The National Institute of Standards and Technology has issued a draft of guidance on mobile security. The guidance defines the fundamental security components and capabilities needed to help mitigate risks involved in using the latest generation of mobile devices.

The guidelines recommend that each mobile device implement three security components that can be employed by the device’s operating system and applications: Root of trust, application programming interface and policy enforcement engine.”]
