Description

This curriculum spans the full lifecycle of IT audits in complex operational environments, equivalent to a multi-phase advisory engagement covering risk assessment, control testing across IAM, change management, cloud, and incident response, and integration with enterprise governance—mirroring the depth and coordination required in a global organization’s internal audit and risk management program.

Module 1: Establishing the IT Audit Framework and Scope

Define audit boundaries for hybrid IT environments integrating on-premises, cloud, and third-party services based on business-criticality and regulatory exposure.
Select an audit framework (e.g., COBIT, ISO 27001, NIST) aligned with organizational risk appetite and compliance mandates.
Negotiate access rights to systems, logs, and configurations across departments with competing operational priorities.
Determine frequency of audits for different system tiers (e.g., real-time monitoring for Tier 0 systems vs. annual for Tier 3).
Document exceptions for systems under active development or undergoing migration to avoid premature audit findings.
Map audit scope to data classification levels to prioritize protection of PII, financial, and intellectual property assets.
Integrate audit scope with enterprise risk assessments to ensure alignment with top organizational risks.
Establish criteria for including or excluding shadow IT systems discovered during discovery scans.

Module 2: Risk Assessment and Control Prioritization

Conduct threat modeling for critical systems using STRIDE or OCTAVE to identify exploitable attack vectors.
Assign quantitative risk scores using FAIR methodology to justify audit focus on high-impact, high-likelihood scenarios.
Identify compensating controls when primary controls are technically infeasible or cost-prohibitive.
Adjust control testing depth based on system criticality, change velocity, and historical incident frequency.
Validate risk treatment decisions (accept, mitigate, transfer, avoid) with documented business owner approvals.
Assess residual risk after control implementation to determine if audit findings require escalation.
Reassess risk profiles quarterly or after major infrastructure changes such as cloud migration or M&A activity.
Balance control effectiveness against operational overhead, particularly in DevOps and CI/CD environments.

Module 3: Audit of Identity and Access Management (IAM)

Review privileged account usage patterns to detect standing privileges that violate least privilege principles.
Audit access certification processes to verify that managers review and approve access at least quarterly.
Validate integration between IAM systems and HR workflows to ensure timely deprovisioning upon employee offboarding.
Assess break-glass account controls, including physical safeguards, logging, and post-use review requirements.
Test MFA enforcement across remote access, administrative portals, and SaaS applications.
Examine role definitions in role-based access control (RBAC) for role explosion or overlapping permissions.
Review API key management practices, including rotation schedules and scope limitations.
Evaluate just-in-time (JIT) access implementation for cloud environments to reduce standing privileges.

Module 4: Change and Configuration Management Audits

Verify that all production changes follow a documented change advisory board (CAB) approval process.
Sample change records to confirm rollback plans are documented and tested prior to implementation.
Assess configuration drift by comparing system configurations against golden images or infrastructure-as-code baselines.
Review emergency change logs to ensure post-implementation review and documentation occurred within 72 hours.
Validate that configuration management databases (CMDBs) are updated within 24 hours of change implementation.
Audit use of automated configuration tools (e.g., Ansible, Terraform) for unauthorized manual overrides.
Check segregation of duties between developers, change approvers, and deployment operators.
Evaluate change freeze windows during critical business periods and adherence during audits.

Module 5: Incident Response and Logging Audit

Review SIEM log retention policies to ensure compliance with legal and regulatory requirements (e.g., 365 days).
Validate that critical systems send logs to centralized logging with write-once, read-many (WORM) protection.
Audit incident response playbooks for completeness, including escalation paths and communication templates.
Test incident response timelines against SLAs (e.g., 15 minutes for detection, 1 hour for initial response).
Verify that root cause analysis (RCA) reports are produced for all severity 1 and 2 incidents.
Assess log integrity controls to prevent tampering, including file integrity monitoring and log signing.
Review false positive rates in alerting systems and their impact on analyst fatigue and response effectiveness.
Validate that incident tickets are closed only after containment, eradication, and lessons learned are documented.

Module 6: Cloud Infrastructure and Service Provider Audits

Map shared responsibility model boundaries to verify customer-managed controls (e.g., IAM, encryption) are implemented.
Audit CSPM (Cloud Security Posture Management) tool findings to assess misconfigurations in public cloud accounts.
Review contractual SLAs and security appendices for third-party providers to validate audit rights and reporting obligations.
Verify encryption of data at rest and in transit across cloud services using customer-managed or BYOK keys.
Assess network segmentation in cloud VPCs/VNets to prevent lateral movement across workloads.
Validate that cloud storage buckets are not publicly accessible by default and are scanned weekly.
Review provider SOC 2 or ISO 27001 reports to confirm control effectiveness and coverage of audited services.
Test disaster recovery failover procedures for cloud-hosted systems at least annually.

Module 7: Data Protection and Privacy Compliance

Trace data flows for regulated data (e.g., GDPR, HIPAA) from ingestion to archival or deletion.
Audit data classification processes to confirm consistent tagging across repositories and applications.
Validate DLP (Data Loss Prevention) policies block or alert on unauthorized transmission of sensitive data.
Review encryption key management practices, including separation of duties and key rotation frequency.
Assess data retention schedules and confirm automated disposal aligns with policy.
Verify that privacy impact assessments (PIAs) are completed before launching new data-processing initiatives.
Check consent management mechanisms for digital services to ensure opt-in/out is recorded and honored.
Test data subject request (DSR) fulfillment processes for accuracy and timeliness (e.g., 30-day response).

Module 8: Business Continuity and Disaster Recovery (BC/DR)

Audit RTO and RPO definitions for critical systems to ensure they reflect current business requirements.
Review BC/DR plan distribution and access controls to ensure availability during outages without unauthorized exposure.
Validate backup integrity by restoring sample datasets and verifying data consistency.
Assess offsite storage conditions for physical media, including environmental controls and access logs.
Review failover testing results to confirm systems meet declared RTOs under realistic conditions.
Verify that contact lists and escalation procedures are updated quarterly and tested.
Examine dependencies between systems to prevent cascading failures during recovery.
Ensure that cloud-based DR solutions maintain separate geographic regions and account isolation.

Module 9: Audit Reporting and Follow-Up

Classify findings using severity levels (critical, high, medium, low) based on impact and exploitability.
Document root causes for control failures rather than symptoms to enable effective remediation.
Set realistic remediation timelines in consultation with system owners and risk management.
Track open findings in a centralized register with ownership, due dates, and status updates.
Conduct follow-up testing to verify that remediation actions fully address the original finding.
Escalate unresolved critical findings to executive management and board-level risk committees.
Archive audit reports and working papers in accordance with document retention policies (e.g., 7 years).
Produce trend reports on recurring findings to identify systemic control deficiencies.

Module 10: Integration with IT Governance and Enterprise Risk

Align audit findings with KRIs and KPIs reported to the IT steering committee or board.
Integrate audit results into the enterprise risk register to update risk scores and treatment plans.
Participate in quarterly risk review meetings to provide assurance on control effectiveness.
Coordinate with internal audit and external auditors to avoid duplication and ensure coverage.
Validate that audit recommendations are incorporated into IT capital planning and budget cycles.
Assess maturity of IT governance processes using models such as COBIT Maturity Model.
Review policy exception logs to detect patterns of non-compliance requiring governance intervention.
Support regulatory examinations by providing audit evidence and control testing documentation.
