How MTA-STS Can Help Secure Exchange Online
As more organizations move to the cloud, they are increasingly looking to secure their data, resources, and applications to protect their users and corporate data. With the rise of cloud-based services, security solutions have become more sophisticated and more critical. In this article, we will explore MTA-STS, a new security feature for Exchange Online that can help organizations protect their Exchange Online environment.
What is MTA-STS?
MTA-STS (Mail Transfer Agent-Security Token Service) is a new security feature for Exchange Online that helps secure email messages transmitted between two different email systems. It provides an additional layer of security by validating the sender’s certificate and verifying the sender’s identity. This helps ensure that messages sent from Exchange Online are not intercepted or tampered with.
How Does MTA-STS Work?
MTA-STS works by using a combination of digital certificates and encryption. When two email systems communicate, MTA-STS will validate the sender’s certificate and verify the sender’s identity. It then uses encryption to protect the message and make sure it is not tampered with. The receiver of the message can then decrypt the message and verify that the sender is who they claim to be.
What Are the Benefits of MTA-STS?
The main benefit of MTA-STS is that it helps protect your Exchange Online environment by ensuring that messages sent from Exchange Online are not intercepted or tampered with. It also helps protect your organization from phishing attacks, as it can help verify the identity of the sender. Finally, MTA-STS helps protect your users’ data by encrypting messages sent from Exchange Online.
How Do I Enable MTA-STS for Exchange Online?
Enabling MTA-STS for Exchange Online is easy and can be done through the Exchange Admin Center (EAC). To enable MTA-STS, log into the EAC, go to the Organization Security & Compliance tab, and then select ‘Enable MTA-STS’. Once you have enabled MTA-STS, you will need to configure the settings for your organization. This includes setting up the certificate, setting up the policy, and configuring the rules for sending messages.
MTA-STS is a powerful security feature for Exchange Online that helps protect your environment from phishing attacks and encrypts messages sent from Exchange Online. It is easy to enable and configure and can help ensure that your organization is secure and compliant with industry standards. By using MTA-STS, you can help ensure that your Exchange Online environment is secure and that your users’ data is safe.
