Mobile devices, including smartphones and tablets, enable increasing numbers of employees to work "anywhere, anytime."The security of enterprise data is a key concern, particularly on mobile devices that are easily lost or stolen. The security risk is further heightened by the proliferation of employee-owned mobile devices in many enterprises. Employees will almost always take the path of least resistance in leveraging mobile devices for business purposes, which may lead to unsafe computing practices. A clearly documented and enforceable mobile security policy is critical to reducing the risk of data loss.
