AudioCodes Private Key The system software on AudioCodes devices is signed with AudioCodes' private key. Users can replace the complete software only with new software that is also signed by AudioCodes' private key. This prevents users from replacing the complete over-the-air (OTA) package of the device with any new system software, unless the software is fully signed by AudioCodes. Android Debug Bridge (ADB) The device does not allow access to ADB.
Device Manager, the user can replace the Root CA on the Device Manager and on the phone, and re-establish the connection leveraging any Private Root CA. Sandboxing AudioCodes devices use Android Application Sandbox so that each application can access its own data and is isolated from other applications. This prevents a malicious app from accessing the code or the data of other applications in the system. Device File System The AudioCodes device's file system is encrypted on C450HD-DBW devices. Customers may enforce a policy of device encryption via Microsoft's cloud-based Intune service. Keystore With AudioCodes devices, the certificate keys are encrypted on the device file system.
