IT Systems Audit & Cybersecurity UAE 2025: ITGC, ISO 27001 & Data Protection
Complete IT systems audit guide for UAE businesses. Master ITGC controls, ISO 27001 certification, penetration testing, PDPL compliance, and cybersecurity audit requirements for financial institutions and regulated entities.
IT Systems Audit & Cybersecurity UAE 2025: ITGC, ISO 27001 & Data Protection
Are your IT systems and cybersecurity controls ready for regulatory scrutiny? As UAE businesses rapidly digitalize operations (87% now run core processes on cloud/SaaS platforms), IT systems audit and cybersecurity compliance have transformed from "nice to have" technical exercises into mandatory regulatory requirements. Financial institutions face Central Bank cybersecurity standards, data processors must comply with PDPL, and all businesses managing sensitive information face growing audit scrutiny on IT general controls (ITGC).
As Ministry-approved auditors conducting 350+ IT systems audits annually (covering everything from AED 50M fintech startups to AED 2 billion manufacturing groups), we've witnessed how inadequate IT controls create cascading audit failures. A typical discovery: Company passes preliminary financial audit fieldwork, then IT systems review reveals no password policies, admin access given to 15+ employees, no backup testing in 18 months, and spreadsheet-based "accounting system"triggering qualified audit opinion despite accurate financial figures.
In this comprehensive guide, you'll discover what constitutes IT systems audit scope and objectives, the five critical IT General Controls (ITGC) domains auditors examine, ISO 27001 information security management system requirements, penetration testing and vulnerability assessment procedures, PDPL and NESA compliance for UAE businesses, specific cybersecurity requirements for financial institutions, and the audit evidence auditors require to validate IT control effectiveness.

Understanding IT Systems Audit
An IT systems audit is a systematic examination of an organization's information technology infrastructure, operations, and controls to ensure they support accurate financial reporting, protect sensitive data, and comply with applicable regulations.
Why IT Systems Audit Matters
Financial Statement Reliability: Modern businesses process 95%+ of financial transactions through IT systems. If IT controls are weak, financial statement accuracy cannot be assured, regardless of how diligent the accounting team is.
Regulatory Requirements: Multiple UAE regulations now mandate IT controls:
- Central Bank: IT Security Standards for Licensed Financial Institutions
- NESA: National Electronic Security Authority standards
- PDPL: Personal Data Protection Law data security requirements
- ISO 27001: Often required by clients/partners
- SOC 2: Required by many international clients
Audit Opinion Impact: External auditors cannot issue unqualified (clean) audit opinion if IT controls are materially weak, even if financial numbers are accurate.
IT Audit Scope
Typical IT Systems Audit Covers:
- IT general controls (ITGC) across key systems
- Application controls in financial systems
- Database security and access management
- Network security and firewall configurations
- Backup and disaster recovery procedures
- Change management for system updates
- Vendor and third-party access controls
- Physical security of IT assets
- Incident response and monitoring
- Data retention and destruction policies
IT Audit vs. Cybersecurity Assessment
Scroll to see all columns →
| Aspect | IT Systems Audit | Cybersecurity Assessment |
|---|---|---|
| Primary Focus | Controls supporting financial reporting accuracy | Protection against external threats |
| Typical Performers | External auditors, internal audit | Security consultants, ethical hackers |
| Key Methodology | Control testing, documentation review | Penetration testing, vulnerability scans |
| Primary Stakeholders | Board, audit committee, shareholders | CISO, CIO, risk management |
| Compliance Driven By | Audit standards (ISA 315, AS 2201) | Security frameworks (ISO 27001, NIST) |
| Output | IT controls assessment, audit opinion impact | Security posture, vulnerability report |
In Practice: Many UAE businesses undergo both IT systems audit (as part of annual financial audit) AND cybersecurity assessment (for ISO 27001, client requirements, or proactive risk management).
What Others Won't Tell You
Most IT systems audit failures occur not from sophisticated technical gaps, but from basic control breakdowns:
- No documentation of who has admin access
- Developers able to change production code without approval
- No testing of backup restoration in 12+ months
- Shared passwords for critical systems
- No logging of privileged user activities
A AED 500M revenue company we audited had invested AED 2 million in advanced threat detection and security operations center (SOC), yet failed IT audit due to: (1) no password expiration policy, (2) terminated employees still had VPN access, (3) no segregation between developers and production database access. The expensive security tools addressed advanced threats while basic hygiene controls remained absent.
Additionally, UAE businesses often underestimate the IT audit scope until too late. Audit planning letter says "we'll review your IT controls," which sounds routine. Then auditor requests:
- Complete list of all users with financial system access (by role and permission level)
- Evidence of security awareness training for all employees
- Change logs for all financial system updates in past 12 months
- Restoration testing results for all backup systems
- Penetration testing reports from independent third parties
- Data classification and encryption policies
Companies without proper IT governance spend AED 40,000-80,000 in rushed remediation and documentation during audit period.
