What Is the HSS Agent?

The HSS agent is used to perform scans on all servers, monitor server security status in real time, and reports collected server information to the cloud protection center.

There are different agent versions for Linux and Windows OSs. The HSS protection functions will be available after you install the agent and enable HSS protection.

Functions of the Agent

  • The agent runs scan tasks every day in the early morning to scan all servers, monitors server security, and reports collected server information to the cloud protection center.
  • The agent blocks server attacks based on the security policies you configured.
  • If the agent is not installed or is abnormal, HSS is unavailable.
  • The agent can be installed on HUAWEI CLOUD Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), offline servers, and third-party cloud servers.
  • WTP and HSS can use the same agent on a server.
