AWS cli: GuardDuty get-custom-detection-rule: add RuntimeMonitoring details

Service: cli · 2026-10-15 · Documentation low

File: cli/latest/reference/guardduty/get-custom-detection-rule.md

Summary

Adds RuntimeMonitoring to the rule type enum and documents RuntimeMonitoringDetails including per-platform (EKS, EC2, ECS Fargate) minimum agent version requirements; bumps CLI reference version to 2.38.1.

Security assessment

Documents GuardDuty Runtime Monitoring rule metadata (a threat-detection capability) but does not address a specific vulnerability or incident; it is security-tooling documentation.
