Define Container Protection rulesets to ensure protection for your containers during Runtime Security scanning.

Procedure

  1. Go to Cloud Security → Container Security → Container Protection.
  2. Click the Rulesets tab.
  3. Create, duplicate, or modify a ruleset.
    • To create a new ruleset, click New.
    • To duplicate an existing ruleset:
      1. Click to select the base ruleset from the policy list.
      2. Click Duplicate.
        Container Protection creates a copy of the existing ruleset and appends "Copy" to the ruleset name.
    • To modify an existing ruleset, click the ruleset in the ruleset list.
  4. For new and duplicated rulesets, specify a unique ruleset name.
    Note
    Note
    • Ruleset names must not contain spaces and only support alphanumeric characters, underscores (_), and periods (.).
    • You cannot modify the ruleset name after creating the ruleset.
  5. If you want to provide more details about the purpose for the ruleset, use the Description field.
    The description appears under the ruleset name in the ruleset list.
  6. For users that have applied labels to your Kubernetes clusters and want to apply the ruleset only to clusters with corresponding labels, click Add Label.
    1. Specify the Key and Value for each label.
    2. If you have multiple labels that you want to apply the ruleset to, click Add Label again.
    Important
    Important
    Labels are only supported on Kubernetes clusters and have no effect on Amazon ECS clusters.
  7. Apply rules to the ruleset by clicking Add Rule.
    1. Select the checkboxes next to the available rules you want to apply to the ruleset.
    2. Click Submit.
    Tip
    Tip
    To get more information about the attack technique that a rule is designed to prevent, search for the MITRE ID (for example T1021.004) on the MITRE site.
  8. In the Mitigation column, select what action you want Container Security to perform when the rule is violated.
    • Log: Log the event but allow the container to continue running
    • Isolate: Isolate the pod from all network traffic (Kubernetes only)
    • Terminate: Terminate the pod (Kubernetes only)
    Important
    Important
    Amazon ECS clusters only support the Log action. If you select to Isolate or Terminate and apply the ruleset to an Amazon ECS cluster, Container Security defaults to the Log action only.
  9. Click Create.
