Configuring HSS for a FlexusX Instance

What Is Host Security Service?

HSS is designed to improve the overall security for cloud servers. It helps you identify and manage the assets on your servers, eliminate risks, and defend against intrusions and web page tampering. There are also advanced protection and security operations functions available to help you easily detect and handle threats.

After installing the HSS agent on your FlexusX instances, you will be able to check the protection status of the instances and risks in a region on the HSS console.

For more information about HSS, see What Is HSS?

Enabling HSS

  • Scenario 1: Enabling HSS when you purchase a FlexusX instance

    When you use a public image to purchase a FlexusX instance, you can choose to enable HSS. The HSS agent will be installed on and HSS will be enabled for the FlexusX instance automatically.

    HSS editions:
    • The HSS basic protection trial edition is free for 30 days. It provides functions such as detection for weak passwords, vulnerabilities, brute-force attacks.

      After the free trial period expires, the HSS basic edition quotas will be automatically released, and HSS will not protect your servers.

    • You can choose from the HSS basic, enterprise, premium, and Web Tamper Protection (WTP) editions, which are charged.

      After the instance is purchased, you can switch between different HSS editions on the HSS console. For details about differences among different editions, see Specifications of Different Editions.

  • Whether HSS is displayed on the FlexusX console depends on the selected images. Certain public images do not support HSS.
  • The supported HSS editions vary with the billing mode and public image. For details, see the supported HSS editions on the management console.
  • Scenario 2: Enabling HSS after a FlexusX instance is purchased

    If you do not enable HSS during the FlexusX instance purchase, you can manually install the agent to use HSS. For details, see Installing an Agent and Enabling Server Protection.

    Before manually installing the agent, check whether the OS is supported. For details, see OS Restrictions.
