Secure Communication Channels in Various Email Services

Securing communication channels in various email services, especially Exchange Server, is a mechanism that organizations try to provide for their network environment. Therefore, the OTP Server platform has provided reliable protection for email services with a forward-looking vision. OTP Server Authentication providers allow you to provide users with MFA access to servers on operating systems such as Linux, Mac, and Windows.



OTP-Exchange is an authentication system for email users to confirm the identity of people and employees of organizations in other ways than having a username and password.



OTP Server offers advanced methods, including online authentication and token compression. For instance, you can expand your Outlook login processes with strong authentication according to your organization’s risk level, which can be implemented in cooperation with Exchange and OTP Server.

According to the active directory structure in organizations, users who are effective in the network can be provided with an environment where they can move their data with a secure connection. Nowadays, the structure of exchange and sending and receiving email is very welcome in sensitive organizations, and network managers are trying to guarantee the security of this sector in the best way. One of the best ways to secure Exchange Server is to use a onetime password structure.


How OTP-Exchange works?

In general, the OTP Server can guarantee the security of Exchange Server in two modes: Outlook Web Access and Outlook software. To gain access, users must first enter the username and password registered in the network and then pass the validation process correctly with the help of OTP. The modular and flexible design enables the OTP Server to adapt and scale with the future scenarios of the organization and grow as the organization expands.

In this structure, the Exchange Server communicates with the OTP Server and sends a message to the user’s mobile phone through the PNP proxy (push token provided) provided by the OTP Server. When a message is sent to the user, Exchange also transmits the confirmation to the OTP Server. Finally, the OTP Server checks the result and determines whether the login is allowed.

The tokens received from the OTP server are usually in different modes, including Time Base and HMAC. When the token is issued after a particular time in the time base mode, its validity ends, and it must be requested from the OTP Server again. In HMAC mode, however, a series of tokens are provided to the user from the OTP server, for which there is no time to be invalidated, and each token becomes invalid once it is used.

In the HMAC structure, the order of the tokens available to the user is important. Token usage makes the previous tokens invalid, so the security reaches its highest level.

Ryan Nik Tajhiz Company provides users with OTPs sent and synchronized with the Exchange server in various forms like SMS, Mobile Authenticator, Push Token, and so on through the OTP Server structure. With this method, you do not have to worry about your passwords being stolen.
