103 732-1
8.3.1 Cryptographic Support (FCS)
A CMD under evaluation may support many cryptographic capabilities to provide the functionality expected by customers of the device. The cryptographic support of the TOE, as a subset of the overall functionality of the device, does not need to include capabilities which do not support the claims being made in the evalu...

103 732-1
8.3.2.1 The Update Policy
The Update Policy defines: • How often the TSF will check whether new app or system software updates are available. • Depending on the update type, the package can update either a single app or portions of the system software. System software updates can also replace the cryptographic data used to determine the validit...

908b1db2923c9d5b9336bc07e544e666
103 732-1
8.3.4 Security Management (FMT)
As the CMD is not a managed device in the enterprise sense, all management is handled locally by the user as opposed to a specific management service as would be the case for an enterprise device. FMT_MSA.1/Permissions Management of security attributes FMT_MSA.1.1/Permissions The TSF shall enforce the [PERMISSIONS POLI...
908b1db2923c9d5b9336bc07e544e666
103 732-1
8.3.5 Privacy (FPR)
To avoid tracking of the unique Device ID of the TOE, the TOE provides aliases of the Device ID for App developers and ad networks. App developers may be able to generate their own aliases on top of ones provided by the TOE itself (these are out of scope) or request the TSF to provide an unique alias for its use. The T...
908b1db2923c9d5b9336bc07e544e666
