 RX-PAD runs the main client and MTR processing (audio, video, sharing)

 The main unit (RXV81 | RXV200) can run as a standalone (using remote / keyboard /

mouse) or paired with the controller

 Both RX-PAD and RXV81 | RXV200 share the same MTR license and account

 The user signs in on both RX-PAD and RXV81 | RXV200, to the same account

 Configuration is ‘shared’ between the Room Controller and the main unit

1.4 Managing RX-PAD

Admins can use AudioCodes Device Manager to manage RX-PAD. Management includes (but is not limited to):

 Monitoring

 Firmware management / upgrade

 Alarm management

Note: For more information, see the Device Manager User & Admin Manual.

User’s and Administrator’s Manual 8 Document #: LTRT-18321

User’s and Administrator’s Manual 1. Introduction

1.5 Security Guidelines

The RX-PAD is an AudioCodes Native Teams Android-based device purpose-built and customized for Teams calling and meeting and designed to enhance security as part of the default use.

Though customers might see Android-based systems as prone to security issues, security is much less a concern on devices that are purpose-built for Teams meeting and calling.

When analyzing the security of the device there are two levels that should be addressed:

 Authentication and security with regards to Teams connectivity and use

 Android level / system of the device

1.5.1 Microsoft Teams Security Guidelines

 Following are AudioCodes’ recommendations with regards to device security:

• Use “sign-in with other device option” – using this mode the user does not type the

password on the device, instead obtains a code to be used to sign-in on his PC/laptop; the device obtains a private token that enables it to access Teams cloud; this token, unlike a password, allows only that device which obtained it to reuse it. The token is stored on the secured file system.

• Leverage Multi-Factor-authentication (MFA) to improve the security of the sign in.

• IT can consider reducing the expiration time of the sign in for devices which are

connected remotely (outside the organization network) vs devices in the organization premise.

 Visit Microsoft technical pages and learn more on security guidelines and policies for

Microsoft Teams adoption:

• Overview of security and compliance - Microsoft Teams | Microsoft Docs

• Identity models and authentication for Microsoft Teams - Microsoft Teams | Microsoft Docs

• Sign in to Microsoft Teams - Microsoft Teams | Microsoft Docs

1.5.2 Android Level Security Hardening

This section describes the major changes performed on the system/Android level that were incorporated into the device to improve its security.

1.5.2.1 Google Play Services

Goggle Play services were removed from the device software – no access is allowed to any Google store or Play services.

 The device update of the Android software and application is done via special software

components that either connect into Teams Admin Center or to AudioCodes Device Manager over secured channel.

1.5.2.2 Running Android in Kiosk Mode

Android Kiosk Lockdown software is the software that locks down the Android devices to just allow the essential apps by disabling access to the Home/Launcher. Using Android Kiosk Lockdown software, the Android devices can be converted into public kiosk terminals or secured work devices.

 Only specific Microsoft apps and AudioCodes signed apps that were certified and approved

in the certification process can run under the Kiosk mode; even if a malicious user managed to install a new un-authorized app on the file system – the launcher on the device will only run those specific approved apps and this cannot be changed in run time (only with new software code that is provided by AudioCodes).

Version 2.2 9 RX-PAD Meeting Room Controller

Page 10

RX-PAD Meeting Room Controller

1.5.2.3 Screen Lock

AudioCodes Native Teams devices use a screen lock mechanism to prevent any malicious user/users from gaining access to Calendar information and / or Active Directory list of employees and / or triggering unauthorized Teams calls from the device. After enabling screen lock, the device automatically locks after a preconfigured period; a code is required to unlock the device and resume full operation.

1.5.2.4 AudioCodes Private Key

The system software on the device is signed with AudioCodes private key – users can replace the complete software only with new software that is also signed by the AudioCodes private key. This prevents the user from replacing the complete OTA package of the device with any new system software unless this software has been fully signed by AudioCodes.

1.5.2.5 Android Debug Bridge (ADB)

AudioCodes disables the Android Debug Bridge (ADB) application and keeps the Teams app running in the front all the time, which means there is no way to install other Apps from unknown sources and sideloading.

1.5.2.6 App Signing

Android requires that all apps are digitally-signed with a developer key before installation; currently the device verifies that the apps are signed by Microsoft. App signing prevents malicious user/users from replacing a Microsoft-signed app with an app that "pretends" to be Microsoft but which lacks the private key that is known only to Microsoft.

1.5.2.7 Web Browser

The device does not include a Web browser – users cannot browse to the public internet or internal intranet– all Web services are customized to connect to O365 services and AudioCodes managed services such as One Voice Operations Center (OVOC).

Without a web browser, malicious user/users will not be able to access the device and browse from it as a trusted device into the customer network.

1.5.2.8 Remote Configuration Management

The Native Teams device does not have an embedded WEB server – configuration and management is performed using one of the following remote interfaces:

 Microsoft Teams Admin Center (for Native Teams devices) over HTTPS protocols – this is

enabled after successful sign-in authentication process.

 AudioCodes Device Manager (part of AudioCodes OVOC suite) over HTTPS.

 Debugging interface over SSH. Note that SSH MUST be disabled by default and enabled

only per specific case for debugging-purposes only.

1.5.2.9 AudioCodes Device Manager Validation

The device validates the AudioCodes Device Manager identity using known root CA:

 The device is shipped with known Root CAs installed. See here.

 For the initial connection phase, the AudioCodes Device Manager should access the device

using a known CA.

 Once a successful secured connection has been established between the device and the

Device Manager, the user can replace the root CA on the Device Manager and on the device and re-establish the connection leveraging any private root CA.

User’s and Administrator’s Manual 10 Document #: LTRT-18321

Page 11

User’s and Administrator’s Manual 1. Introduction

1.5.2.10 Sandboxing

AudioCodes Native Teams 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.

1.5.2.11 Keystore

With AudioCodes Native Teams devices, the certificate keys are encrypted on the device file system.

1.5.2.12 Device Certificate

AudioCodes Native Teams devices are shipped with a unique certificate which is signed by AudioCodes Root CA.

1.5.2.13 Data Protection

AudioCodes Native Teams devices run Android which has integral procedures for protecting and securing user data.

1.5.2.14 Device File System

The device file system is encrypted on the device – customers may enforce a policy of device encryption via Microsoft Intune.

1.5.2.15 Debugging Interface

 The device leverages SSH as a debugging interface.

 AudioCodes recommends that customers disable SSH on the device – this can be done via

the AudioCodes Device Manager (OVOC).

 AudioCodes recommends changing the Admin password from the default, which can be

done via Teams Admin Center or AudioCodes Device Manager (OVOC).

 When debugging of a specific device is required, the user can enable SSH on specific

device/s, access SSH with the new Admin password for debugging phase and disable SSH once debugging has been completed.

1.5.3 Android Security Updates

In addition to all the above, AudioCodes regularly adopts and integrates the Android security updates. For reference see here

5.12 Screen Capture

By default, this setting is enabled. If disabled, the device won't allow its screens to be captured.

5.13 Performing Recovery Operations

While RX-PAD is powering up, admin can perform recovery operations by inserting a sharp pointed object, for example, a paper clip or pin, into the pinhole button shown below and pressing for the length of time shown in the table below.

When pressing the pinhole button, the device’s main LED changes color after every n seconds; each color is aligned with a recovery operation option.

Note:

• Besides manual recovery options, Android devices also feature an independent, automatic

problem detection and recovery attempt capability that can culminate in recovery mode or in switching image slots.

• Android devices also feature a ‘hardware watchdog’. This feature resets the device if

Android is stacked and doesn’t respond (though Android stacking is unlikely); there’s no recovery process; the device is only reset.

Use this table as reference as to how to use the pinhole button to perform recovery operations.

6 Updating Microsoft Teams Devices Remotely

For instructions on how to update Microsoft Teams devices remotely, see here.

Note: Before an update is pushed to a device, the firmware detects whether the user is using

the device or not. If they are, the user is notified and given an option to delay the update or apply it, nonetheless. The feature avoids disrupting users’ ongoing activities on their devices, such as calls.
