Dear Alibaba Cloud users,
To improve the performance of the Deep Packet Inspection (DPI) engine of Cloud Firewall, Cloud Firewall rolls out an update for the DPI engine starting July 8, 2024.
Update schedule
July 8, 2024 to December 19, 2024
Impacts
Cloud Firewall optimizes the recognition mechanism for traffic over various protocols, including Zabbix, MsSQL-TDS, DNS, PostgreSQL, SMB, SOCKS, IMAPS, POP3, POPS, SMTP, FTP_CONTROL, Memcache, MongoDB, MQTT, MySQL, RDP, Redis, SSH, VNC, HTTP, SSL, HTTPS, SMTPS, Kafka, and Thrift.
After the update, the recognition rate of preceding 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
We recommend that you pay attention to the traffic hits of access control policies configured based on the preceding applications. If errors occur, modify the access control policies in a timely manner.
If you have questions, submit a ticket.
