PP-MDF-333250
Group -
Google Android 15 must be configured to not allow backup of [all applications, configuration data] to remote systems.
Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the mobile operating system (MOS). Where the r...Rule Medium Severity -
PP-MDF-333260
Group -
Google Android 15 must be configured to enable authentication of personal hotspot connections to the device using a preshared key.
If no authentication is required to establish personal hotspot connections (Wi-Fi and Bluetooth), an adversary may be able to use that device to perform attacks on other devices or networks without...Rule Medium Severity -
