Security Guidelines for Android-based Native Teams Devices
AudioCodes' Android-based Native Teams devices are purpose-built and customized for
Microsoft Teams calling and meeting. Customers might perceive Android-based products as vul-
nerable to security issues but security is
less
of an issue on devices purpose-built and cus-
tomized for Microsoft Teams calling and meeting. Security is in fact
enhanced
on these devices
as part of their default use
.
When analyzing device security, two levels must be addressed:
■
Authentication and security with respect to Teams connectivity and use
■
Android level / system of the device
AudioCodes recommends the following:
■
Use the sign-in mode
Sign-in with other device option
. In this mode, users do not type the
password on the device but instead obtain a code on their PC / laptop to be used to sign-in;
the phone 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 sign-in security.
■
Reduce the expiration time of the sign-in for devices which are connected remotely
(outside the organization's network) versus devices inside the organization's premises.
AudioCodes recommends visiting Microsoft's technical pages for more security guidelines and
policies for Microsoft Teams adoption:
