User's & Administrator's Manual 1. Introduction
Version 1.13 11 RXV80 Standalone Video Collaboration Bar
1.3 Security Guidelines
The RXV80 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
1.3.1 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
1.3.2 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.
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.
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).

RXV80 Standalone Video Collaboration Bar
User's & Administrator's Manual 12 Document #: LTRT-18173
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.
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.
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.
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.
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.
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.
AudioCodes Device Manager Validation
The IP phone validates the AudioCodes Device Manager identity using known root CA:
The device is shipped with known Root CAs installed. See AudioCodes Root CA Certificate.
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 phone
and re-establish the connection leveraging any private root CA.

User's & Administrator's Manual 1. Introduction
Version 1.13 13 RXV80 Standalone Video Collaboration Bar
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.
Keystore
With AudioCodes Native Teams devices, the certificate keys are encrypted on the device file
system.
Device Certificate
AudioCodes Native Teams devices are shipped with a unique certificate which is signed by
AudioCodes Root CA.
Data Protection
AudioCodes Native Teams devices run Android which has integral procedures for protecting and
securing user data.
Device File System
The device file system is encrypted on the RXV80 device – customers may enforce a policy of
device encryption via Microsoft Intune.
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.
1.3.3 Android Security Updates
In addition to all the above, AudioCodes regularly adopts and integrates the Android security
updates. For reference see https://source.android.com/security/bulletin/2019-10-01 ).
