Technical Knowledge
During a quarterly audit of a mid‑size financial firm, the audit team needed to evaluate the existing ITGC framework.
Identify and explain the essential control categories that constitute a robust ITGC.
Described the five core components—Access Controls, Change Management, Operations Controls, Backup & Recovery, and Security Monitoring—detailing how each mitigates specific risks and aligns with regulatory expectations.
The audit report highlighted gaps in change management, leading to immediate remediation and improved compliance posture.
- Can you give an example of a control failure in one of these areas?
- How do you test the effectiveness of these controls?
- Clarity in enumerating components
- Depth of explanation for each control
- Connection to risk and compliance
- Use of concrete examples
- Vague list without explanation
- Missing key component such as Change Management
- No link to regulatory requirements
- Identify the five core ITGC components: Access, Change Management, Operations, Backup/Recovery, Security Monitoring
- Explain purpose of each component and associated risks
- Link components to regulatory standards (e.g., SOX, ISO 27001)
- Provide examples of typical controls within each area
A client planned to migrate a critical application to a SaaS platform and requested an IT audit risk assessment.
Determine the risk exposure associated with the new provider and recommend mitigation steps.
Conducted a vendor risk questionnaire, reviewed SOC 2 and ISO 27001 reports, performed data classification mapping, evaluated data residency and encryption controls, and ran a quantitative risk model to estimate potential financial impact.
Delivered a risk assessment report that identified three high‑risk areas—data residency, insufficient logging, and third‑party sub‑processor oversight—leading the client to negotiate stronger contractual clauses and implement supplemental monitoring.
- What specific metrics would you include in your risk scoring model?
- How would you handle a provider that lacks a SOC 2 report?
- Comprehensiveness of assessment steps
- Use of quantitative risk analysis
- Awareness of regulatory implications
- Practical mitigation recommendations
- Skipping vendor certifications review
- Only qualitative assessment without metrics
- Ignoring data residency concerns
- Gather provider certifications (SOC 2, ISO 27001)
- Map client data classifications to provider controls
- Assess data residency, encryption, and access management
- Quantify potential impact using a risk scoring model
- Recommend mitigation (contractual clauses, supplemental controls)
Risk & Controls
During a yearly audit of a retail bank’s loan processing system, I discovered that user access rights were not revoked after employee termination.
Report the weakness, assess its impact, and drive remediation to prevent unauthorized access.
Documented the control gap, quantified the risk by estimating potential fraudulent transactions, presented findings to the IT security steering committee, and collaborated with HR and IT to implement an automated de‑provisioning workflow integrated with the identity management system.
The new workflow reduced orphaned accounts by 95% within three months, and the bank avoided a potential regulatory finding during the subsequent external audit.
- What metrics did you use to quantify the risk?
- How did you ensure senior management prioritized the remediation?
- Clear articulation of the weakness
- Quantitative risk estimation
- Stakeholder engagement and communication
- Effective remediation and measurable outcome
- No quantification of risk
- Blaming others without proposing solutions
- Lack of measurable results
- Identify the control weakness (orphaned accounts)
- Quantify risk (potential fraud exposure)
- Communicate findings to stakeholders
- Lead remediation (automated de‑provisioning)
- Measure post‑remediation results
Our client, a publicly traded manufacturing company, was preparing for its annual SOX 404 assessment of IT controls.
Design and execute an audit approach that verifies ITGCs meet SOX requirements.
Mapped IT processes to SOX control objectives, performed walkthroughs of access provisioning, change management, and backup procedures, tested control design and operating effectiveness, documented evidence in a compliance portal, and coordinated with external auditors for final sign‑off.
All ITGCs were deemed effective, resulting in a clean SOX opinion and no material weaknesses reported for the fiscal year.
- Which specific ITGCs are most scrutinized under SOX?
- How do you handle a control that fails testing?
- Understanding of SOX control objectives
- Methodical testing approach
- Evidence management practices
- Collaboration with auditors
- General statements without process mapping
- Ignoring testing of operating effectiveness
- No mention of remediation steps
- Map IT processes to SOX control objectives
- Perform walkthroughs and document control design
- Test operating effectiveness (sample testing)
- Maintain evidence in a centralized repository
- Collaborate with external auditors for sign‑off
Behavioral
The organization’s legacy VPN solution lacked multi‑factor authentication, exposing remote access to credential‑theft risk.
Convince the CFO and CIO to allocate budget for a modern zero‑trust network solution.
Prepared a business case quantifying potential breach costs, benchmarked industry best practices, presented risk heat‑map visuals, highlighted regulatory implications (e.g., GDPR), and proposed a phased rollout with ROI calculations.
Management approved a $250K investment, and the new solution reduced unauthorized access incidents by 80% within six months, also satisfying audit recommendations.
- What ROI metrics did you include?
- How did you address concerns about implementation disruption?
- Clear risk articulation
- Financial justification
- Effective communication style
- Outcome measurement
- Only technical jargon without business impact
- No ROI or cost analysis
- Failure to mention regulatory drivers
- Identify the security gap (no MFA)
- Quantify potential breach impact
- Develop ROI and risk heat‑map
- Present regulatory and compliance drivers
- Propose phased implementation plan
