What Is ISO 27001 Audit?

An ISO 27001 audit is an assessment process conducted to verify that an organization’s ISMS complies with the ISO 27001 standard. The audit is typically performed by an accredited certification body or an internal team trained in ISO 27001 standards. It involves a detailed examination of the organization’s information security policies, procedures, and controls.

How To Get ISO 27001 Audit Checklist?

Obtaining an ISO 27001 audit checklist involves several steps:

Identify the Scope of the Audit-

Determine the boundaries of your ISMS, including the processes, departments, and information assets that will be covered by the audit. This will help you tailor the checklist to your organization’s specific needs.

Form an internal group-

Assemble an internal resource team to lead your company’s compliance process and serve as a point of reference for the certification audit. Heads of People Operations, Security Officers, and IT departments, among others, might be on this team.

This group would be involved in all phases of the ISMS’s design, construction, and oversight. Consequently, during the certification audit, is in the greatest position to respond to the questions posed by the external auditor.

Align ISMS Scope and Plan-

Work together with department leaders and go over the details of your ISO 27001 certification. The information, goods, procedures, services, systems, roles, affiliates, and regions that your company needs to safeguard with its ISMS may serve as the basis for this. Make sure the scope includes all the data that your company wants to safeguard with an ISMS. Look for the results of internal audits about this matter, then take the advice to heart.

Examine the documentation-

Verify that management has seen and approved each of the several ISO 27001 papers, including the Information Security Policy, Risk Treatment Plan, and Statement of Applicability, to mention a few. Additionally, record all policies and make them accessible to all employees on the corporate intranet.

Gathering of evidence-

To prove compliance with the ISO standard standards, make sure there is a trail of papers and records and that proof is gathered. For example, post policies on the corporate intranet that pertain to vendor risk management, change management, data backup, business continuity, vulnerability management, and data retention, among others, and make them accessible to all employees.

Review and Update Regularly-

The audit checklist should be a living document, updated regularly to reflect changes in your ISMS or new ISO 27001 requirements.

Include the results of internal audits-

Examine the internal audit report, making sure to take into account all of the conclusions, suggestions, and remedial measures. One of the first things your external auditor would check for during the primary audit would be your internal audit report.

Inquire about the following throughout the audit:

  • Are industry-standard encryption and HTTPS (TLS algorithm) being used to safeguard user access to your application?
  • Is it the case that every year top management evaluates and approves all corporate policies?
  • Is information security awareness training completed by all employees both at the time of recruitment and on an annual basis?
