ISO 27001 audit checklist

Implementing an ISO 27001-compliant Information Security Management System (ISMS) can be challenging. However, acquiring the ISO 27001 certification can prove to be a sound business decision, due to the many benefits it begets. Reduction of the need for frequent audits, improvement in the company structure and focus, avoidance of regulatory fines and protection of the company’s reputation from security threats are just some of the benefits of acquiring this certification.

ISO 27001 internal audit checklist

If you are considering acquiring the certification, we have compiled a nine-step implementation roadmap that will guide you. The following article contains an ISO 27001 audit checklist that will help you to achieve compliance without overlooking any important elements. You can leave the ISO 27001 audit process to us using ISO consulting services.

Step 1: Assemble an implementation team

The first step of the ISO 27001 audit checklist is to appoint a project leader who will oversee the implementation and management of the ISMS.

The project leader should have a well-rounded knowledge of information security as well as experience in leading a team.

They should have acquaintance with authority and should be able to give orders and review departments whenever needed.

A project team is also needed to handle the processes of ISMS. Senior management can select between themselves or allow the team leader to choose their own staff depending upon their capabilities. Once the team is assembled, a project mandate should be created. The project mandate essentially highlights what the ISMS is hoping to achieve, the approximate time it will take, the approximate budget and the resources needed. In order to get the ISO 27001 certificate, this step is very important.

Step 2: Development of the implementation plan

In the next step, it is necessary to begin planning for the implementation exit. The implementation team will utilise their project mandate to create a more detailed outline of their information security objectives, plans and potential risks. To set out high-level policies, it is important to establish the roles and responsibilities of all team members.

Additionally, rules for its continual improvement should be chalked out. Lastly, it is also necessary to plan how the team will raise awareness of the project across the organisation. In other words, the internal and external communication channels need to be identified. In the article What is ISO 27001, complete information about the implementation of ISO 27001 is provided.

Step 3: initiate the ISMS

With the plan in place, it is now time to determine a methodology for continual improvement. ISO 27001 recommends a process approach that is based on the “plan-do-check-act“ strategy. By using this model and the recommendations provided, an ISMS policy can be created. The policy needs to be supported by a well-organised document structure. Utilising a four-tier strategy for your document structure will assure compliance and quality.

The four-tier strategy states that the policies defining the organisation’s position on specific issues such as password management should be at the top. Procedures, policy requirements and work instructions describing how employees should meet these policies should come next. The last layer should include reports tracking the procedures and the work instructions. It is very important to follow these tips in order to become ISO 27001 lead auditor.

Step 4: Define the ISMS scope

In the next step, it is necessary to gain a broader sense of the ISMS framework. This step is essential to defining the scale of your ISMS, allowing it to reach the level of efficiency to streamline your day-to-day operations. This process is outlined in ISO 27001 clauses four and five standards.

Defining the core of ISMS involves identifying the locations where the information is stored and understanding if it is kept in physical or digital files, systems or portable devices. Correctly defining the score is essential for effective implementation.

Step 5: Identifying your security baseline

An organisation’s security baseline is the minimum level of activity required to conduct business security. The ISO 27001 risk assessment can be utilised to identify your security baseline. This step will allow you to identify your organisation’s most significant security vulnerabilities. Additionally, the controls outlined in in Annex A of ISO 27001 can be utilised to mitigate these risks.

Step 6: Establish a risk management process

Almost every aspect of the security system is based on the threats that you have identified and prioritised. Risk management is a core competency for any organisation that is implementing ISO 27001. The standard allows organisations to define the risk management process by focusing on specific assets. Irrespective of the individual asset you opt for, the risk assessment begins by establishing a risk assessment framework and identifying risks.

Analysing and evaluating risks is the next step that would allow you to select the most appropriate risk management options. Additionally, organisations need to establish their risk acceptance criteria or the level of damage these risks will cause in the likelihood of them occurring. A large part of the benefits of ISO 27001 depends on the correct implementation of this step.

Step 7: Implementing a risk treatment plan

Implementing a risk treatment plan is the process of building security controls that will protect your organisation’s information assets. To ensure the effectiveness of the controls, it is necessary to test the staff’s ability to operate and interact with the controls. Moreover, it is also necessary to test the staff’s knowledge about information security obligations. This will allow the organisation to develop a process to review and maintain the competencies necessary to achieve the ISMS objectives.

Step 8: Measure, monitor and review

The review process involves identifying criteria that reflect the objectives of the project mandate. Quantitative analysis is commonly used to review the efficiency of the ISMS. Quantitative analysis helps in determining the financial cost and running time of the ISMS. Alternatively, qualitative analysis can be done when measurements are based on judgement.

In addition to this process, it is necessary to conduct regular internal audits to identify any underlying noncompliances. Regular internal audits also help to prevent a significant loss in productivity and ensures that the team’s efforts are spread evenly across various tasks.

Step 9: Certify your ISMS

You can choose to acquire ISO 27001 certification once the ISMS is in place. In this case, it is important to prepare for an external audit. An external audit would review the efficiency of the ISMS to ensure that all noncompliances have been eliminated and the processes are in compliance with the recommendations of the standard.
