Agent Overview

What Is an Agent?

The HSS agent is a piece of software installed on cloud servers to exchange data between the servers and HSS, implementing security detection and protection. If no agent is installed, the HSS is unavailable.

Scans all servers at 00:00 every day; monitors the security and monitors status of servers; and reports the collected server and monitors information (including non-compliant configurations, insecure configurations, intrusion traces, software list, port list, and process list) to the cloud protection center. In addition, the agent blocks attacks targeted at servers and containers based on the security policies you configured.

Supported OSs

Currently, some mainstream OSs are supported. For details, see Supported OSs. To obtain better HSS service experience, you are advised to install or upgrade to an OS version supported by the agent.
