Preparing for a Compliance Audit: A Checklist

Compliance audits (e.g., SOC 2, HIPAA, GDPR, ISO 27001, PCI DSS) can be daunting, but proper preparation ensures a smooth process and avoids costly penalties. Use this checklist to organize your documentation, policies, and security controls before auditors arrive.

Pre-Audit Preparation Steps
1. Identify the Compliance Requirements
Confirm which standards apply (e.g., HIPAA for healthcare, PCI DSS for payments).

Review the audit scope (what systems, processes, and data are in scope?).

Assign an internal compliance lead to manage the process.

2. Conduct a Self-Assessment (Gap Analysis)
Compare current practices against compliance requirements.

Identify missing controls (e.g., encryption, access logs, incident response plans).

Document gaps and create a remediation plan.

3. Gather Required Documentation
📌 Policies & Procedures

Information Security Policy

Acceptable Use Policy

Incident Response Plan

Business Continuity & Disaster Recovery (BC/DR) Plan

Data Retention & Disposal Policy

📌 Technical & Administrative Controls

Access control logs (who accesses what data?)

Employee security training records

Vendor risk assessments (if using third-party services)

Patch management logs (proving regular updates)

📌 Evidence of Compliance

Previous audit reports (if applicable)

Risk assessment reports

Backup & recovery test results

Security awareness training completion records

During the Audit: Best Practices
Be transparent – Hiding issues can lead to worse penalties.

Have a single point of contact for auditor questions.

Keep documentation organized (use a secure shared drive).

Address minor findings immediately if possible (shows good faith).

Post-Audit Steps
✅ Review the auditor’s draft report for accuracy.
✅ Address any non-compliance findings with a corrective action plan (CAP).
✅ Schedule follow-up audits if required (e.g., for SOC 2 Type 2).
✅ Update policies annually to stay compliant.
