Red Hat Security: Identity Management and Active Directory Integration (RH362) — Lesson 4: High Availability, Security, Backup, Monitoring, Troubleshooting, and Recovery

Learning Objectives

• Operate, troubleshoot, document, and improve high availability, security, and backup.
• Apply monitoring and troubleshooting and recovery while preserving reviewable technical evidence.
• Recognize and correct the risk where the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete.

Detailed Topics

• high availability: apply the concept to an identity team integrating RHEL systems with a centralized identity service and Microsoft Active Directory, record the relevant settings or decisions, and explain the operational consequence.
• security: apply the concept to an identity team integrating RHEL systems with a centralized identity service and Microsoft Active Directory, record the relevant settings or decisions, and explain the operational consequence.
• backup: apply the concept to an identity team integrating RHEL systems with a centralized identity service and Microsoft Active Directory, record the relevant settings or decisions, and explain the operational consequence.
• monitoring: apply the concept to an identity team integrating RHEL systems with a centralized identity service and Microsoft Active Directory, record the relevant settings or decisions, and explain the operational consequence.
• troubleshooting and recovery: apply the concept to an identity team integrating RHEL systems with a centralized identity service and Microsoft Active Directory, record the relevant settings or decisions, and explain the operational consequence.

Instructor Demonstration

The instructor demonstrates high availability, security, backup, monitoring, troubleshooting, and recovery by tracing the relevant architecture, commands, configuration, messages, and evidence. The walkthrough highlights how the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete and shows how to isolate the cause without masking dependent issues.

Hands-On Exercise

Run an operational review and produce support-ready evidence for High Availability, Security, Backup, Monitoring, Troubleshooting, and Recovery. Add verified outcomes to the IdM deployment design, trust configuration evidence, policy baseline, and identity support runbook.

1. Confirm the scope, versions, access, dependencies, and success criteria.
2. Perform the workflow while recording commands, settings, output, and platform events.
3. Test one expected case and one controlled exception specific to this lesson.
4. Retest the correction and document ownership, rollback, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences high availability in the stated scenario.
• Compare two approaches for monitoring and explain the security, reliability, and support trade-offs.
• Decide what evidence must be retained in the IdM deployment design, trust configuration evidence, policy baseline, and identity support runbook before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check monitoring, troubleshooting, rollback, ownership, and handover separately, then correlate logs, events, commands, and configuration history. Do not accept the initial assumption that the technical fix is successful but monitoring, rollback, ownership, or handover remains incomplete; confirm the cause with a reproducible retest.

Validation Checklist

• The required monitoring, troubleshooting, rollback, ownership, and handover were checked and recorded.
• The normal path and a course-specific exception were tested.
• The IdM deployment design, trust configuration evidence, policy baseline, and identity support runbook links conclusions to commands, configuration, logs, or other objective evidence.
• Corrective actions, rollback steps, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply High Availability, Security, Backup, Monitoring, Troubleshooting, and Recovery, explain the observed Red Hat platform behavior, and support the result with a reviewable IdM deployment design, trust configuration evidence, policy baseline, and identity support runbook.
