What are ISO 27001 Policies?
ISO 27001 policies are statements of what you do for information security. They are shared with customers, employees and auditors. They clearly set out the information security requirements and approach of the organisation.

Time needed: 1 day and 4 hours
How to write ISO 27001 policies
- Write your information security policy
The main policy is the information security policy. It is a high level policy. Follow ISO 27001 Information Security Policy: How to Write (& Template)
- Complete the ISO 27001 Statement of Applicability
The ISO 27001 Statement of Applicability is the list of information security controls that you have chosen to implement. Based on the controls that you have chosen you will write policies that cover those controls. Follow ISO 27001 Statement of Applicability Beginner’s Guide
- Write topic specific policies
For the controls that you have chosen in your ISO 27001 Statement of Applicability, write policies for them. An example list of topic specific policies:
Data Protection Policy
Data Retention Policy

ISO 27001 Document and Record Policy - Share them for review and update as needed
Share the policies with those that understand the areas that are covered to provide input and changes that are appropriate
- Set the version control for a stable version
For the first implementation set the version of all documents to version 1.
- Approve the policies
The oversight body that you have should review the policies and sign them off with the meeting documented and minuted. Hold a Management Review Team Meeting and record in the minutes that you reviewed and approved the Policies with a list of the policies and versions in the minutes.
- Make the policies available
Put the policies on an area accessible internally by all staff. This could be a share point or a shared drive.
- Communicate that the new version of policies is available, where they are and direct people to read them
Communicate using different means where the policies are and that people should read them.
- Include them in your communication plan and training plan for the year
Create a communication plan and follow it so that polices are communicated and also that they are signed up to by staff.
- Review them annually or after a significant change and repeat the process
Policies are not static so be sure to review them as things change and / or at least annually.
ISO 27001 Policy Templates
All of the required information security policies for ISO 27001 are included in the ISO 27001 Policy Template Toolkit. They are already written and ready to go. If you want to fast track then get a copy of the toolkit.
How to implement ISO 27001 Clause 5.2 Policies
The ISO 27001 requirement for policies comes from ISO 27001 Clause 5.2 and this is a great introduction to the wider requirements of the ISO 27001 policies.
Which ISO 27001 Policies Do I Actually Need?
Potentially all of them. Remembering that these are information security policies. They rely on other company policies to satisfy the requirements of an effective ISMS. Most notably would be your HR policies and documents such as Company Handbook, Grievance Policy and more.
If you have a GDPR or Data Protection implementation already you are not going to need the Data Protection Policy and Data Retention Policy.
The policies are modular to meet the requirements of many standards. To meet those standards, you may need tweaks. They fully satisfy ISO 27001 and the foundation of any good ISMS.
As discussed, the policies are based on the Context of Organisation. Specifically, the statement of applicability will be a guide. If you do not have one, have not completed a context of organisation or this concept is alien to you then the simple approach is to look at each policy and ask your self – does this look like it applies here?
Let us take Secure Development Policy as an example. If you do not do Secure Development, then it is unlikely this policy is needed for you.
How often should ISO 27001 policies be updated, reviewed and reissued?
At least annually within a 12-month period. Or when a significant change occurs.
Common ISO 27001 Policies Mistakes
The first thing any auditor is going to do is look at the document mark up. 99 times out of 100 hundred this is wrong in some way. It is an easy win.
- What is the Version number of the document? Is it the same in the header and footer and document version control?
- When was the document last signed off? Was it within the last year?
- Does the document have an owner, and do they still work here if a named person?
