Questions tagged [mobile]

Security in mobile devices. Issues concerning regular cellphones, smartphones, tablet computers and other portable information devices all fit into this category. If your question is specific to one of the following, use it instead: [phone], [smartphone], [iphone], [ios], [windows-phone], [android].

Security in mobile devices - smartphones, netbooks, laptops, blackberries and other computing or communication devices not typically classified as desktop or server.

The rise of mobile devices brings novel risks: the traditional view of a company's computers being inside some privileged boundary with everyone else being outside the same perimeter can no longer be applied. Questions relating to understanding the threat model of mobile devices, configuring security features of particular mobile platforms and addressing mobile-specific security issues all belong in the tag.
