Description
Wi-Fi Sharing is an optional configuration of Wi-Fi Tethering/Mobile Hotspot, which allows the device to share its Wi-Fi connection with other wirelessly connected devices instead of its mobile (cellular) connection. Wi-Fi Sharing grants the "other" device access to a corporate Wi-Fi network and may possibly bypass the network access control mechanisms. This risk can be partially mitigated by requiring the use of a preshared key for personal hotspots. SFR ID: FMT_SMF_EXT.1.1 / WLAN #3
