This scenario highlights the dangers of end-user tools becoming production systems without governance.

You’ll learn:

✔ What CISA really tests under Shadow IT & End-User Computing

✔ Why EUC tools become high-risk when they support critical processes

✔ How junior auditors think vs. how audit leaders assess governance maturity

✔ What evidence auditors must review: formulas, macros, access rights, documentation

✔ How to identify ungoverned systems that silently shape business decisions

✔ How to evaluate risk and recommend migration to supported platforms

This episode is foundational for mastering operational and governance risks in Domain 4.

This episode is part of the CISA Domain 4 Deep-Dive Series, a structured curriculum that covers every subtopic in the 26% Information Systems Operations & Business Resilience domain. Each episode blends CISA exam reasoning with real-world audit leadership.

In this episode, we investigate a scenario where a critical job ran successfully — but processed zero records for two weeks because its input file never arrived. The scheduler marked the run “successful,” yet the business experienced silent data failure. This episode exposes the difference between automation and governed automation.

You’ll learn:

✔ What CISA really tests for job scheduling and automation

✔ Why processing integrity matters more than “successful” job status

✔ The evidence auditors must review: inputs, dependencies, reconciliation, exception logs

✔ How silent failures occur in automated workflows

✔ The operational, financial, and compliance risks of missing inputs

This episode builds mastery in one of the most heavily tested Domain 4 subtopics.

In Episode 24, we examine a scenario where dozens of production servers existed — but none were recorded in the official CMDB. These assets were unpatched, unmonitored, unowned, and unprotected. The result: massive hidden risk despite a “complete” inventory on paper.

You’ll learn:

✔ What CISA really tests under IT Asset Management

✔ Why unknown assets are more dangerous than broken systems

✔ How junior auditors interpret inventory vs. how audit leaders evaluate accuracy

✔ 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

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

In this episode, we explore a scenario where DLP is fully implemented and generating alerts — but no one is reviewing them. This exposes a critical truth in cybersecurity: tools only create visibility; governance creates protection.

You’ll learn:

✔ Why DLP review and governance are major Domain 5 exam themes

✔ Why “having a tool” does NOT mean “having a control”

✔ How junior auditors interpret DLP vs. how audit leaders evaluate it

✔ What evidence auditors must review for DLP and monitoring governance

✔ How to assess ownership, escalation, triage, and review maturity

✔ How CISA designs questions around unreviewed alerts

✔ The real risk when alerts exist but no one investigates them

CISA Domain 4: Backup, Storage & Restoration Controls

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

In this episode, we investigate a scenario where backups ran successfully for months — but none of them could be restored. This exposes one of the biggest weaknesses in IT operations: assuming backup success equals recovery readiness.

You’ll learn:

✔ Why restoration testing is a major CISA Domain 4 exam theme

✔ Why backup success ≠ backup integrity

✔ How junior auditors interpret backup logs vs. how audit leaders evaluate resilience

✔ What evidence auditors must review for backup and recovery audits

✔ How to assess integrity checks, testing frequency, RPO/RTO alignment

✔ What CISA is actually testing with backup-related questions

✔ The operational risk when backups pass but recovery fails

This episode blends CISA exam reasoning with real audit leadership — the hallmark of the CyberLex Audit Judgment Series.

CISA Domain 5: Encryption & PKI Controls

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 tested sections of the CISA exam.

In this episode, we examine a scenario where TLS encryption is enabled — but certificate validation is disabled. The connection is encrypted, but authentication is nonexistent. This reveals a critical misunderstanding in many organizations: encryption alone does not guarantee secure communication.

You’ll learn:

✔ Why encryption alone is NOT sufficient

✔ Why CISA tests PKI, trust chains, and certificate validation

✔ How junior auditors interpret encryption vs. how audit leaders evaluate authenticity

✔ What evidence auditors should review for encryption and PKI controls

✔ How to assess certificate validation, hostname checks, and PKI governance

✔ What CISA is actually testing in encryption-related exam questions

✔ The risk implications when encrypted traffic is unauthenticated

This episode blends CISA exam reasoning with real audit leadership, helping you think like an auditor — not a technician.
