The mobile enterprise faces unique legal, security, ethical and technical risks as well as concerns that also apply to traditional businesses. This paper reviews the impact of warchalking and wardriving in a legal and security context with a view to formulating technical and legal policy suggestions for technologists, scientists, managers and government policy makers. To assist in addressing these problems, the researchers have developed a preliminary Mobile Enterprise Security and Legal (MELS) Framework. It is adapted from the Network Security Wheel and the Confidentiality, Integrity and Availability (CIA) Security model. This paper outlines the types of threats that impact on the mobile enterprise and illustrates the reactions from international and national legal communities.
