It System Audit Checklist
IT system audits evaluate technology infrastructure for reliability, security, and business alignment. This 12-section checklist covers system architecture, development processes, configuration management, and operations. Verify database performance, system security controls, interface reliability, and performance monitoring. Review availability targets, change management procedures, data management, and system documentation. Applies to custom applications, ERP systems, databases, and integrated platforms. Identifies technical debt, security vulnerabilities, and operational inefficiencies. Recommended for major systems annually or after significant changes. Average audit duration: 5-15 days depending on complexity.

How the It System Audit Checklist works
Phase 1 (Planning): Define scope, identify stakeholders, request architecture diagrams, system documentation, and change logs from last 6 months. Phase 2 (Technical Review): Analyze database performance metrics, review application code quality, test system interfaces with 100+ sample transactions. Check configuration against security baselines. Review error logs and incident reports. Phase 3 (Operations Assessment): Interview system administrator, database administrator, and 5-10 end users. Observe backup and recovery procedures. Test disaster recovery plan. Phase 4 (Reporting): Create findings document with technical details, business impact assessment, and remediation roadmap. Present to IT management and business stakeholders.
System failures disrupt business operations costing $300,000 per hour for large enterprises. Poor performance frustrates users and reduces productivity 15-25%. Security vulnerabilities in business systems expose sensitive data and enable fraud. This audit identifies problems before they cause outages or breaches. Organizations conducting regular system audits reduce unplanned downtime 40-60% and improve system performance 25-45%. Systematic reviews catch configuration drift, identify upgrade needs, and optimize resource usage. Well-maintained systems last 3-5 years longer reducing replacement costs.
