How Does the Baidu Messaging System Ensure Its Security? What Types of Security Are Supported?

The Baidu Messaging System (BMS) ensures its security with the following measures:

• Customer authentication: Because the user can access the message center on line, the user needs authentication to obtain the corresponding identity to read and write topics. Currently, the BMS supports the user in obtaining its identity with the X509 Certificate.
• Customer authorization: After the authentication, the identity is granted, and can be bound with different privileges according to its authorization granularity. Currently, read and write strategies, and the privilege of publishing and subscribing all topics under this user account are available.
• Transmission security: To ensure that data is not eavesdropped and tampered with during the transmission process, SSL encryption is used.

How Does the BMS Ensure Data Reliable?

The number of replicas of the BMS is 3 by default, and data is saved for 24 hours.
