Constraints and Limitations

Supported Server Types

Elastic Cloud Server (ECS)
Bare Metal Server (BMS)
Huawei Cloud Workspace
Third-party cloud server
On-premises server

Currently, only some regions support access to non-Huawei Cloud servers. For details about the regions, see Where Is HSS Available?

Supported OSs

HSS uses the agent to monitor security risks and defend against external intrusions. To protect a server with HSS, ensure the agent is up and running on the server. For more information, see Supported OSs.

The agent is probably incompatible with the Linux or Windows versions that have reached end of life. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
If a piece of third-party security software, such as McAfee, has been installed on your server, stop the protection function on the software before installing an HSS agent. After you install the agent, you can re-enable the protection function on the software.
CentOS 6.x is no longer updated or maintained on the Linux official website, and HSS no longer supports CentOS 6.x or earlier.
