Secure services
BR/EDR
BLE
Applications use Bluetooth services to exchange information between paired devices. Because all data must be treated as untrusted, applications must implement appropriate controls to ensure that both incoming and outgoing data are properly validated and handled securely.
Description
To verify that Bluetooth services used by applications are implemented securely, the following recommendations can be employed:
- Source Code Review: Provides a comprehensive view of the implementation and allows validation of whether it’s a secure implementation.
- Fuzzing: Allows for the creation of data flows that are not as expected by the application, and in the event of validation issues in their content, it can reveal faults in a device.
- Reverse Engineering: If the source code is not available, reverse engineering can be used to evaluate the mechanisms handling data for implementation issues.
The ultimate goal of this control is to ensure that in the face of random data inputs, the application can maintain its integrity and functionality.
