ISO 27001 Certification Audit: How is it Conducted?
ISO 27001 certification evaluates whether an organization has established and effectively implemented an Information Security Management System (ISMS) that aligns with international standards. The audit process is essential for determining if the organization has adequately implemented security measures. This audit is an integral part of the certification procedure and must be repeated periodically for each organization.
When applying for the ISO 27001 certification, the certification body conducts an audit to assess how well the organization’s ISMS and internal processes align with ISO 27001 standards. This article explains the step-by-step process of the ISO 27001 audit and how QRS Certification can assist you throughout.
ISO 27001 Audit Stages
Organizations seeking ISO 27001 certification undergo a two-phase audit process: Stage 1 (Documentation Review) and Stage 2 (Main Audit). These stages evaluate the establishment and operation of the organization’s ISMS.
Stage 1: Documentation Review
In the first phase, the certification body reviews the documentation related to the organization’s ISMS. This includes efforts to establish the ISMS, risk assessments, information security policies, procedures, and practices. Stage 1 aims to assess whether the organization meets ISO 27001 requirements and identifies any gaps.
Key elements assessed during Stage 1:
Risk assessment and management
Information security policies and procedures
Training and awareness programs
Documentation of information security processes
Internal audit reports and corrective actions
At the conclusion of Stage 1, the auditor provides a report outlining identified gaps and listing corrective actions required to proceed to Stage 2.
Stage 2: Main Audit
In Stage 2, the certification body audits the actual implementation of the ISMS and evaluates its effectiveness. This phase involves on-site observations, interviews with employees, and document checks. The auditor examines how well the organization complies with ISO 27001 standards, typically lasting several days.
Key elements assessed during Stage 2:
Application of the ISMS throughout the organization
Employee awareness of information security
Conducting security audits and tests
Effectiveness of internal control mechanisms
Management oversight and control of the ISMS
After the audit, the certification body provides a report assessing the organization's compliance level. Any deficiencies will prompt corrective actions. Once these actions are taken, the certification is issued.
