Managing Server Security
What Is Host Security Service?
Host Security Service (HSS) 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 Host Security Service.
Enabling HSS
Before using the HSS service, install the agent on your FlexusX instance. You can install the agent during or after the creation of a FlexusX instance.
- Scenario 1: During the creation of a FlexusX instance
When you use certain public images to purchase FlexusX instances, you are advised to use HSS to protect your instances.
Select one of the following options:- HSS basic edition (free): provides HSS basic edition (1-month free trial), account cracking protection, weak password detection, and malicious program detection.
After the free trial period expires, the HSS basic edition quotas will be automatically released, and HSS will not protect your servers.
If you want to retain or upgrade HSS security capabilities, you are advised to purchase HSS. For details, see Editions and Features.
This option is selected by default.
- Advanced HSS edition (paid): provides HSS enterprise edition, vulnerability patches, virus scan and removal, and graded protection.
- None: Do not use security protection.
HSS provides basic, enterprise, premium, and WTP editions. For details, see Edition Details.
If the basic or enterprise edition does not meet service requirements, you can Purchasing an HSS Quota and switch the edition on the HSS console to obtain advanced protection without reinstalling the agent.
Different public images support different HSS versions. See the supported HSS versions on the management console.
- HSS basic edition (free): provides HSS basic edition (1-month free trial), account cracking protection, weak password detection, and malicious program detection.
- Scenario 2: After a FlexusX instance is purchased
If you did not select HSS or the selected image does not support HSS when purchasing a FlexusX instance, you need to manually install the agent to use HSS.
For details, see Installing an Agent and Enabling Server Protection.
