Does anyone know the technicality of how Apple has implemented VPN via iPhone (iOS 7). &nbsp;I need to know if my iPhone is leaking information when in standby via 4G/LTE once Wi-Fi goes out (which is typical to save battery life even when Wi-Fi is still strong and active).<br />

Thank you all.

Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.
