[Enhancement]: Add EKS Runtime monitoring to Guard Duty

[be-aws-architect]

Description

Guard Duty now supports EKS Runtime monitoring, but it is not configurable in Terraform at the moment.

Affected Resource(s) and/or Data Source(s)

• aws_guardduty_detector
• aws_guardduty_organization_configuration

Potential Terraform Configuration

It currently allows EKS Audit Logs in the format

resource "aws_guardduty_detector" "MyDetector" {
  enable = true

  datasources {
    s3_logs {
      enable = true
    }
    kubernetes {
      audit_logs {
        enable = false
      }
    }


It would look like 

resource "aws_guardduty_detector" "MyDetector" {
  enable = true

  datasources {
    s3_logs {
      enable = true
    }
    kubernetes {
      audit_logs {
        enable = true
      }
      runtime {
       enabled = true
    }

This should probably also include not just the runtime, but also the runtime agent deployment:

As EKS Runtime Monitoring is an EKS add-on, I'm wondering if the deployment of the runtime agent would be done by using the existing aws_eks_addon resource? It looks like that's designed in a pretty generic way so maybe it won't need changes.

That said, it would be helpful to have a bit of documentation on how to configure the monitoring agent, as it seems like there are at least a few config options and it would be good to have an example. Perhaps the config would sit under the aws_guardduty_organization_configuration resource, or perhaps some might end up under aws_eks_addon, it would be good to understand where it would go and what it would look like.

The add-on needs to be enabled for the agent to gather events and send them to Guardduty but the Guardduty feature needs to be enabled nevertheless.

Example CLI command:

aws guardduty update-detector --detector-id 12abc34d567e8fa901bc2d34e56789f0 --acount-ids 555555555555 --features '[{"Name" : "EKS_RUNTIME_MONITORING", "Status" : "ENABLED", "AdditionalConfiguration" : [{"Name" : "EKS_ADDON_MANAGEMENT", "Status" : "DISABLED"}] ]'

No, that is something else. This is the org wide auto enablement of the deployment of that EKS addon and is a guardduty setting. You can of course manually deploy it, but that is not what we are talking about here.

You will be able to use the upcoming aws_guardduty_detector_feature resource (#31463):

resource "aws_guardduty_detector" "example" {
  enable = true
}

resource "aws_guardduty_detector_feature" "example" {
  detector_id = aws_guardduty_detector.example.id
  name        = "EKS_RUNTIME_MONITORING"
  status      = "ENABLED"

  additional_configuration {
    name   = "EKS_ADDON_MANAGEMENT"
    status = "ENABLED"
  }
}
