“Secure Your Exchange Online with Throttling and Blocking of Persistently Vulnerable Servers”
Throttling and Blocking Email from Persistently Vulnerable Exchange Servers to Exchange Online
Introduction
As cloud adoption continues to increase, it is important to consider the security of your cloud environment. In particular, it is critical to prevent malicious actors from gaining access to your cloud resources. Microsoft Exchange Online is a cloud-based communication platform that provides the features and services to help organizations stay productive and connected. To protect the security of your Exchange Online environment, Microsoft has implemented a throttling and blocking mechanism to mitigate vulnerabilities in Exchange Servers.
What is Throttling and Blocking?
Throttling and blocking is a mechanism used to limit the amount of resources that Exchange Online can use when communicating with a vulnerable Exchange Server. When Exchange Online detects that a vulnerable Exchange Server is sending traffic, it will throttle the traffic and eventually block the connection. This prevents malicious actors from using the vulnerable Exchange Server to gain access to the Exchange Online environment.
How Does Exchange Online Throttle and Block Traffic?
Exchange Online uses a combination of technologies to detect and throttle vulnerable Exchange Servers. When a connection is detected from a vulnerable Exchange Server, Exchange Online will begin to throttle the connection. This throttling process is designed to limit the amount of data that can be sent from the Exchange Server to Exchange Online. After a certain amount of time, Exchange Online will block the connection and prevent any further communication from the Exchange Server.
What are the Benefits of Throttling and Blocking?
Throttling and blocking provide an additional layer of security to help protect your Exchange Online environment. By throttling and blocking traffic from vulnerable Exchange Servers, you can prevent malicious actors from using the vulnerable Exchange Server to gain access to your Exchange Online environment.
Conclusion
Throttling and blocking is an important security mechanism that helps protect your Exchange Online environment. By throttling and blocking traffic from vulnerable Exchange Servers, you can prevent malicious actors from using the vulnerable Exchange Server to gain access to your Exchange Online environment. Although this security mechanism is important, it is also important to ensure that your Exchange Server is properly configured and secure to protect against vulnerabilities.
