DO430 – Securing Kubernetes Clusters with Red Hat Advanced Cluster Security — Lesson 1: RHACS Architecture, Central, Sensors, Collectors, Deployment, and Access

Learning Objectives

• Explain the architecture, purpose, dependencies, and expected behavior of RHACS architecture, Central, and Sensors and Collectors.
• Apply deployment and access control while preserving reviewable technical evidence.
• Recognize and correct the condition where an unstated prerequisite or ownership gap causes the initial design to be incomplete.

Detailed Topics

• RHACS architecture: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Central: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• Sensors and Collectors: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• deployment: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• access control: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates rhacs architecture, central, sensors, collectors, deployment, and access by tracing architecture, commands, configuration, system messages, and evidence. The walkthrough tests how an unstated prerequisite or ownership gap causes the initial design to be incomplete and explains how to isolate the cause without masking related issues.

Hands-On Exercise

Establish a controlled baseline for RHACS Architecture, Central, Sensors, Collectors, Deployment, and Access and add the verified result to the RHACS deployment baseline, security policy set, vulnerability evidence, runtime alerts, and response playbook.

1. Confirm scope, versions, access, dependencies, assumptions, and acceptance criteria.
2. Perform the workflow while recording commands, configuration, output, events, and decisions.
3. Test the normal path and one course-specific exception or boundary condition.
4. Retest the correction and document rollback, ownership, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences RHACS architecture in the stated scenario.
• Compare two approaches for deployment and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the RHACS deployment baseline, security policy set, vulnerability evidence, runtime alerts, and response playbook before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, scope, identities, prerequisites, and starting conditions separately, then correlate logs, events, commands, metrics, and configuration history. Treat the assumption that an unstated prerequisite or ownership gap causes the initial design to be incomplete as a hypothesis until a reproducible retest confirms the cause.

Validation Checklist

• The required architecture, scope, identities, prerequisites, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The RHACS deployment baseline, security policy set, vulnerability evidence, runtime alerts, and response playbook links conclusions to commands, configuration, logs, metrics, or other objective evidence.
• Corrective actions, rollback, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply RHACS Architecture, Central, Sensors, Collectors, Deployment, and Access, explain the observed platform behavior, and support the result with a reviewable RHACS deployment baseline, security policy set, vulnerability evidence, runtime alerts, and response playbook.
