CISA Domain 4: IT Components Deep Dive

This episode is part of the CISA Domain 4 Deep-Dive Series, a structured curriculum designed to cover every subtopic in the 26% Information Systems Operations & Business Resilience domain. Each episode blends CISA exam reasoning with real-life audit judgment and operational leadership.

In Episode 23, we explore a system that everyone depended on — yet no one fully understood. This scenario highlights the risks of undocumented architecture, unclear ownership, hidden dependencies, outdated components, and unmanaged integrations.

You’ll learn:

✔ What CISA really tests under “IT Components”

✔ How junior auditors see outages vs. how audit leaders assess architecture

✔ Why undefined ownership and missing documentation are major audit findings

✔ What evidence auditors must review for IT component analysis

✔ How to identify risks hiding in dependencies, integrations, and technical debt

✔ How systems can appear stable while being structurally fragile

This episode builds true audit judgment — the capability CISA exams reward.

CISA Domain 5: Security Testing & Coverage Assurance

This episode is part of the CISA Audit Judgment Series — a structured, scenario-based learning path focused on Domains 4 and 5, the most heavily weighted sections of the CISA exam.

In this episode, we examine a scenario where penetration testing was performed — but not against the actual production system.

The test returned zero findings, not because the environment was secure, but because the wrong system was tested.

This reveals one of the most common failures in security governance: false confidence caused by incorrect testing scope.

You’ll learn:

✔ Why CISA focuses heavily on test scope, not test results

✔ How junior auditors interpret clean reports vs. how audit leaders evaluate coverage

✔ What evidence auditors must review to verify security testing maturity

✔ How to assess scope approval, asset inventory accuracy, and representativeness

✔ How CISA designs exam questions around false assurance and missing coverage

✔ The operational and governance risks of testing the wrong system

This episode teaches CISA exam reasoning and real audit leadership judgment — the essence of the CyberLex Audit Judgment Series.

CISA Domain 4: Business Continuity & DR Governance

This episode is part of the CISA Audit Judgment Series — a structured learning path focused on Domains 4 and 5, the heaviest-weighted areas of the CISA exam.

In this episode, we analyze a Disaster Recovery test that was declared “successful” — even though no real failover occurred, no production data was restored, and no business validation took place. The test passed on paper, but not in reality. This scenario exposes a major gap in operational resilience maturity.

You’ll learn:

✔ Why CISA focuses on DR test evidence, not documentation

✔ Why DR tests fail despite official reports showing success

✔ How junior auditors interpret DR vs. how audit leaders evaluate capability

✔ What evidence auditors must review for DR governance

✔ How to assess RTO/RPO validation, test scope, and business involvement

✔ What CISA is actually testing in continuity and recovery questions

✔ The risks when DR tests pass on paper but fail in practice

This episode teaches CISA exam judgment and real audit leadership — the core of the CyberLex Audit Judgment Series.
