Handling Unsafe Containers

Scenario

HSS can detect container security risks and classify them into the following types:

• Critical: malicious program
• High risk: ransomware attacks, malicious programs, reverse shells, escape attacks, and dangerous commands
• Medium risk: web shell, abnormal startup, process exception, and sensitive file access
• Low risk: brute-force attack

To prevent containers with medium or higher security risks from affecting other containers, you can isolate, suspend, or stop risky containers.

Constraints

• Only the HSS container edition supports this function. For details about how to purchase and upgrade HSS, see Purchasing an HSS Quota and Upgrading Your Edition.
• Only Linux containers are supported.
• Only containers with medium or higher security risks can be handled.

   Only containers with medium or higher risks can be handled. You can view the security risk distribution.

   • Isolate containers: After a container is isolated, you cannot access the container when the container is running, and the container cannot access the mount directory of the host or the system file of the container.
     1. Click Isolate.
     2. In the dialog box that is displayed, click OK.
   • Suspend containers: Freeze the processes running in the container.
