Audit and Assurance Policy Template
Summary
Establishes an audit and assurance program for evaluating control effectiveness, compliance, and accountability. Covers audit governance, planning, independence, evidence handling, reporting, remediation tracking, confidentiality, attestations, and readiness for security assessments.
Purpose
This policy establishes the framework for audit and assurance activities within the organization. It outlines responsibilities for conducting audits, verifying control effectiveness, and ensuring accountability across teams. The goal is to promote continual improvement, risk-informed decision-making, and preparedness for external attestation.
Scope
This policy applies to all audit and assurance activities, internal and, where applicable, external or third-party engagements, within the organization. It includes responsibilities of auditors and auditees, covers both operational and security-related audits, and applies to all employees, teams, and systems subject to audit or review. This includes process/policy compliance audits, technical security assessments (e.g., vulnerability scans, penetration tests), vendor and third-party audits for critical suppliers, and internal readiness reviews for external audits or attestations (e.g., SOC 2, ISO 27001).
