Dear Alibaba Cloud users,
To improve the recognition rate of traffic applications for access control policies that are configured on the Internet firewall, Cloud Firewall optimizes the Deep Packet Inspection (DPI) engine for access control policies by updating the Internet Firewall feature. The update task starts on August 1, 2023.
Update schedule
August 1, 2023 to September 30, 2023.
Impacts
Cloud Firewall optimizes the recognition mechanism for traffic over the MySQL, MQTT, and MongoDB protocols.
After the update, the recognition rate of MySQL, MQTT, and MongoDB applications is improved. The recognition results for some traffic may change. If you have configured an access control policy, the traffic hit results of the policy may also change.
Suggestions
If you have enabled the Internet firewall and configured access control policies, you can go to the Traffic Logs tab to view the applications that are recently identified, the traffic hits of access control policies, and the impacts on your business.
If access errors occur, we recommend that you modify the access control policies. For example, if traffic was allowed before the update but is blocked after the update, you can add an access control policy to allow the traffic and specify a higher priority for the new policy.
