Internal audits of ISO 27001 are important to the success of your information security management system (ISMS). They ensure that your ISMS is effective and compliant with the standard. In this blog post, we will discuss how to conduct an internal audit of ISO 27001. We will outline the steps of the audit process so that you can ensure your organization is prepared for a successful audit.
Why Internal Audit in ISO 27001?
Any organization that wants to implement ISO 27001 must have an internal audit function. Internal audit provides assurance to management that the ISMS is operating as intended and that controls are effective. Without an internal audit, it would be difficult to objectively assess the ISMS and identify opportunities for improvement. Furthermore, an internal audit helps to ensure that the ISMS is continually evolving to meet the ever-changing needs of the organization. By conducting regular audits, Internal Audit provides a systematic and independent assessment of the adequacy and effectiveness of the ISMS.
Derive an Internal Audit Programme
An internal audit program is a plan that outlines the approach, scope, and methodology of the audit. An internal audit program should be derived from an understanding of the organization’s risks, objectives, and business processes. The program should be tailored to the specific needs of the organization and should be reviewed on a regular basis to ensure that it is still relevant. By taking a strategic approach to internal auditing, organizations can gain insights into how well their risk management, control, and governance processes are working and make improvements where necessary.
Make a Specific Audit Plan
After the internal audit program has been derived, a specific audit plan should be created for each audit. The audit plan should describe the objectives of the audit, the scope of the audit, and the methodology that will be used. It should also identify the resources that will be required and the timeframe in which the audit will be conducted. By taking the time to create a well-thought-out audit plan, organizations can ensure that their audits are conducted efficiently and effectively.
How is the Frequency of Internal Audit Determined?
The frequency of internal audits is determined by the organization’s risk appetite and the results of previous audits. Organizations that have a high-risk appetite may elect to conduct audits on a more frequent basis, while those with a low-risk appetite may only conduct audits on an annual or biennial basis. The results of previous audits should also be taken into account when determining the frequency of internal audits. If an audit reveals significant deficiencies, the organization may elect to conduct follow-up audits more frequently until the deficiencies have been addressed.
Qualification Required
To be able to conduct effective internal audits, You should have completed ISO 27001 internal auditor training course and should have an ISO 27001 internal auditor certificate. This will ensure that you have a good understanding of ISO 27001 and the auditing process. You should also have strong analytical and problem-solving skills. Additionally, you should be able to communicate effectively, both verbally and in writing. The ability to work independently and as part of a team is also essential.

Role of Internal Auditors in the ISO 27001 Audit
- Planning: Internal auditors play a vital role in the planning of ISO 27001 audits. They are responsible for ensuring that the audit scope is adequate, the objectives are clear, and the methodology is appropriate. They also need to identify the resources that will be required and the timeframe in which the audit will be conducted.
- Conducting Audit through Checklist: Once the audit plan has been finalized, internal auditors will conduct the audit using a checklist. A checklist refers to the list of activities to be completed during the audit. This helps to ensure that all aspects of the ISMS are audited and that all relevant evidence is collected.
- Recording NC: Non-conformity (NC) refers to any deviation from the requirements of ISO 27001. Internal auditors are responsible for recording any non-conformities that are identified during the audit. They will also evaluate the severity of each non-conformity and give feedback to the organization to address them.
- Taking Corrective Action: If any significant deficiencies are identified during the audit, the organization has to develop and implement corrective action plans. These plans should be designed to address the root cause of the problem and prevent it from happening again in the future.
- Verifying Corrective Action: Once corrective action plans have been put in place, internal auditors will verify that they are effective. This may involve re-auditing the areas where deficiencies were found or conducting interviews with employees.
The role of internal auditors in ISO 27001 audits is to ensure that the audit is conducted effectively and that any deficiencies are addressed. By taking the time to plan and prepare for the audit, internal auditors can ensure that the audit is conducted efficiently and that its results are accurate.
