Review whether the systems supporting your business have appropriate access, change, backup, application and data controls — without confusing an IT control audit with penetration testing.
An information system audit reviews how technology is governed and controlled, including who can access systems, how changes are made, whether backups and operational processes are defined, and whether important applications support reliable information.
The scope can include accounting systems, ERP platforms, cloud applications and other systems central to financial or operational processes.
This rebuild deliberately removes unverified CISA claims, fixed breach-reduction percentages, uptime guarantees and broad claims that ZeroSync performs penetration testing.
An IT controls review is not automatically a cybersecurity penetration test, vulnerability scan, ISO certification audit or regulatory certification. Those services require their own specialist scope and capability.
Joiners, movers, leavers, privileged access, role design and periodic user review.
Request, approval, testing, migration and emergency changes.
Scheduled jobs, monitoring, incident handling and operational responsibilities.
Backup schedules, retention, monitoring and evidence that recovery procedures are considered.
Service ownership, access, contracts, dependencies and oversight of outsourced technology.
Whether governance documents reflect actual technology responsibilities and escalation processes.
Where accounting or ERP applications support billing, purchasing, inventory or financial reporting, application controls can influence whether data is complete, authorised and processed consistently.
| Application area | Example review question |
|---|---|
| Customer/vendor master | Who can create or change master records? |
| Payments | Can one user create and approve the same payment? |
| Journal entries | Are manual entries subject to appropriate approval? |
| Reporting | Do key reports use controlled data sources and parameters? |
| Interfaces | Are failed or duplicate interface transactions monitored? |
Identify users, roles, privileged accounts and key applications.
Check whether access has an appropriate business owner and approval.
Identify incompatible access combinations in sensitive workflows.
Perform periodic user and privileged-access recertification.
Ensure leavers and obsolete access are removed in a controlled way.
System changes can affect calculations, interfaces, reports and user workflows. The review can assess whether changes are documented, approved, tested and moved into production through a controlled process.
Emergency changes may need an expedited path, but the business should still preserve evidence of the reason, approval and follow-up review.
Review how data passes between systems and how failed, missing or duplicate transfers are identified.
Consider whether important administrative or operational activities are logged and reviewable.
Review scheduled backup processes, exceptions, retention and recovery responsibilities.
Review how system issues are recorded, prioritised, resolved and analysed for recurrence.
Assess whether key reports are complete, accurate and generated from controlled data sources.
Identify critical systems and whether responsibilities exist for disruption and recovery planning.
The old page claimed Big 4 expertise, CISA-certified experts, specific breach reductions, fine avoidance, penetration testing and 99% uptime. Those claims are removed.
Systems, processes and controls included in the scope.
Evidence reviewed and observations from selected control tests.
Prioritise issues by impact, likelihood and dependency.
Practical actions, owners and follow-up priorities.
Information System Audit: access, change, operations, application and data controls.
Operational Audit: end-to-end business process design and effectiveness.
Internal Control Audit: broader control design and operation around financial/operational risks.
Information-system access should reflect job responsibilities. Where one user can initiate, approve and record the same sensitive transaction, the business may depend too heavily on detective review after the event.
| Process | Potential conflicting access example |
|---|---|
| Vendor management | Create vendor + approve vendor + release payment |
| Customer / credit | Create customer + change credit limit + approve sales exception |
| Journal entries | Create journal + approve/post journal |
| Payroll | Maintain employee bank data + approve payroll payment |
| System administration | Develop/change configuration + migrate own change to production |
The exact evidence depends on the systems and scope. A focused request list reduces disruption and makes testing more efficient.
Define business requirements, data ownership, access roles and control requirements before implementation.
Separate developers and testers where practical and document key configuration decisions.
Validate transactions, reports, interfaces and migrated data before production use.
Monitor access, changes, incidents, jobs and backup exceptions.
Reassess users, roles, vendors and key controls as the business changes.
Access roles, automated workflows, master data, posting rules and reporting.
User rights, journal controls, period locking, bank integrations and audit trails.
Customer master data, pricing/approval workflows and integration with billing.
Employee master data, sensitive access, payroll changes and payment files.
Order feeds, gateways, refunds, interfaces and reconciliation of transaction data.
User lifecycle, administrator access, service dependencies and data ownership.
An information system audit reviews controls around technology, applications, data and IT processes to determine whether they support reliable operations and appropriate access, change, backup and information controls.
No. This page is focused on information-system and IT control review. Penetration testing, vulnerability exploitation and specialist cybersecurity testing require separate technical scope and appropriate specialist capability.
IT general controls commonly include user access management, change management, system operations, backups, incident handling and other controls that support reliable operation of applications and data.
Yes. The review can examine user roles, approval workflows, master-data changes, interfaces, automated controls and other system features that affect financial or operational information.
No. This rebuild deliberately avoids claiming CISA, ISO 27001 certification or other credentials unless ZeroSync can independently verify the specific professionals and scope involved.
No. A control review can identify design or implementation weaknesses, but it cannot guarantee that a system will never experience an outage, breach or security incident.
The report can describe the scope, systems reviewed, control observations, evidence tested, risk classification and recommended remediation actions.
IT audit focuses on technology and information controls. Operational audit focuses on business processes and performance. The two can overlap where an ERP or application is central to the process.
ZeroSync can review selected IT control areas and provide a practical findings and remediation report.
