Purchasing and Enabling Container Security

Scenario

A container cluster consists of a set of nodes. The HSS container edition uses nodes as protection units and provides functions such as container firewall, container cluster protection, and container image security scanning, helping enterprises solve container environment problems that cannot be achieved by traditional security software. For details about the server security protection functions provided by HSS container edition, see Product Functions.

The following is an example to describe how to buy and enable container protection.

Figure 1 Installing an agent

**Table 2** Parameters for installing the agent
Parameter	Example	Description
Installation Mode	CLI-based installation	GUI: You need to provide server account password or key for installing the agent. HSS does not save the password file you upload. To install the agent in this mode, ensure there is already an executor ECS, which is an ECS with an online agent in the same VPC as the target ECS. CLI: You need to log in to the server and run commands or scripts. This method is used when you install the agent for the first time.
Owner Account	Current account	Current account installation: The server and the HSS quota you purchased are under the same account. You can log in to the account to obtain the installation commands or script and install the agent on the server. Cross-account installation: The server and the HSS quota you purchased are not under the same account. You can log in to account A to obtain the installation command or script and install the agent on the target server under account B. After the agent is successfully installed, you can view the target server on the Asset Management > Servers & Quota page of account A.
Server OS	Linux	Select an OS type based on the server OS.
Scale	A single	Select the scale based on the number of servers on which the agent is to be installed.

(Optional) Select the servers that need to be connected to the current HSS region and click Next.
- Perform this operation only in the CN East2 and CN Southwest-Guiyang1 regions. HSS will automatically create a VPC endpoint, which occupies an IP address of your VPC subnet. Only one VPC endpoint will be created for each of your VPCs to ensure the communication between your servers and HSS.
- In other regions, ensure the security groups of your servers allow outbound traffic through port 10180 of the 100.125.0.0/16 CIDR block. This port is used to communicate with HSS.
Install the agent as prompted.

For CN East2 and CN Southwest-Guiyang1 regions, wait until the network communication succeeds (that is, the VPC endpoint is created) before performing the following operations.
1. On the console page, click in the Install HSS Agent dialog box to copy the installation command.
  Figure 2 Copying the installation command
2. Log in to the server as the root user and paste the installation command.
  If the command output shown in Figure 3 is displayed, the agent has been installed.
  
  Figure 3 Agent installed
Wait for 5 to 10 minutes and return to the HSS console. On the Server Install & Config page, click the Agents tab, and click Servers with Agents. Check the agent status of the target server.

If the Agent Status is Online, the agent is successfully installed.

Step 3: Enable Protection

In the navigation pane, choose Asset Management > Containers & Quota.
In the Operation column of a server, click Enable.

In the dialog box that is displayed, select the mode.

**Table 3** Parameters for enabling protection

Follow-Up Procedure

Enable server protection for container nodes.

HSS container edition provides some proactive functions for servers. These functions are not enabled or not completely enabled when container security protection is enabled. You can determine whether to use these functions based on your requirements, the following table Table 4 describes the functions.

**Table 4** Container node protection functions
Function	Description
Container Image Security Scanning	The container image security scanning function scans for vulnerabilities and malicious files in images. You are advised to scan images periodically so that you can handle image security risks in a timely manner.
Ransomware Prevention	Ransomware is one of the biggest cybersecurity threats today. Ransomware can intrude a server, encrypt data, and ask for ransom, causing service interruption, data leakage, or data loss. Attackers may not unlock the data even after receiving the ransom. HSS provides static and dynamic ransomware prevention. You can periodically back up server data to reduce potential losses. Ransomware prevention is automatically enabled with the container edition. HSS will deploy honeypot files on servers and automatically isolate suspicious encryption processes. You can modify the ransomware protection policy. You are also advised to enable backup so that you can restore data.
Application Protection	To protect your applications with RASP, you simply need to add probes to them, without having to modify application files.
Application Process Control	HSS can learn the characteristics of application processes on servers and manage their running. Suspicious and trusted processes are allowed to run, and alarms are generated for malicious processes.
Virus Scanning and Removal	The function uses the virus detection engine to scan virus files on the server. The scanned file types include executable files, compressed files, script files, documents, images, and audio and video files. You can perform quick scan and full-disk scan on the server as required. You can also customize scan tasks and handle detected virus files in a timely manner to enhance the virus defense capability of the service system.
Container Cluster Protection	HSS can check for non-compliance baseline issues, vulnerabilities, and malicious files when a container image is started and report alarms on or block container startup that has not been unauthorized or may incur high risks. You can configure container cluster protection policies to block images with vulnerabilities, malicious files, non-compliant baselines, or other threats, hardening cluster security.
Container Firewall	A container firewall controls and intercepts network traffic inside and outside a container cluster to prevent malicious access and attacks.
Policy Management	HSS comes in multiple editions, including basic, professional, premium, WTP, and container editions. Except for the basic edition, they each have a default protection policy group. A policy group is a collection of policies. These policies can be applied to container nodes to centrally manage and configure the sensitivity, rules, and scope of HSS detection and protection. You can customize policies for asset management, baseline inspection, and intrusion detection as needed. Some policies in the policy group are not enabled by default. You can enable them as needed.
