What is ISO 27001 Annex A 5.1?

ISO 27001 Annex A 5.1 Policies for Information Security is an ISO 27001 Annex A control that requires an organisation to have an information security policy and topic specific policies in place, communicated, reviewed and acknowledged.

I like this change from the old ISO 27001:2013 version as it calls out explicitly now that a pack or suite of policies will be required rather than just the headline information security policy.

ISO 27001 policies are statements of what you do for information security and are used to communicate to staff what must be done and to customers what you do.

Purpose

The purpose of the Annex A 5.1 Policies for Information Security is to ensure the suitability, adequacy and effectiveness of managements direction and support for information security.

Definition

ISO 27001 defines ISO 27001 Annex A 5.1 as:

Information security policy and topic-specific policies should be defined, approved by management, published, communicated to and acknowledged by relevant personnel and relevant interested parties, and reviewed at planned intervals and if significant changes occur.

If you are resolutely dead set on going through the pain of this yourself you are going to need copies of the relevant standards for information security, about 1 to 2 months of your life dedicated to this and a lot, and I mean a lot, of patience.

How to comply

To comply with ISO 27001 Annex A 5.1 you are going to implement the ‘how’ to the ‘what’ the control is expecting. In short measure you are going to

• Write an ISO 27001 information security policy
• Supplement that information security policy with topic specific policies
• Ensure your policies are classified and have document mark up
• Have the policies approved by management and have evidence of that happening
• Publish the policies to a place everyone that needs to see them can see them
• Tell those people where those policies are
• Communicate your policies as part of your communication plan and document you did it
• Get people to acknowledge the policies and keep evidence that they have
• Plan to review your policies at least annually or if significant change occurs
• Keep records of your policy review and the changes

What the auditor will check

The audit is going to check a number of areas for compliance with Annex A 5.1. Lets go through them

1. That you can link policy to requirements

What this means is that you need to show that your policies are linked

• to the business strategy, which you recorded and evidenced in the ISO 27001 organisation overview template.
• to the law, regulations and contracts , which you recorded in the ISO 27001 legal register.
• to risks, which you recorded in your ISO 27001 risk register.

2. That your policy includes required statements

For the main ISO 27001 information security policy there are some required statements that need to be included. You need to

• define information security and the confidentiality, integrity and availability definition
• include your information security objectives
• include principles that will guide on information security activities activities
• include a commitment to satisfy applicable requirements related to information security
• have a commitment to continually improving your information security management system
• assign responsibilities for information security management to defined roles
• cover how you handle exemptions and exceptions.

3. That top management approved the policy

The audit will look to see that the main ISO 27001 information security policy and the topic specific policies have been approved and signed off by top management. The level will have been defined in your ISO 27001 Roles and Responsibilities Template document in line with ISO 27001 Annex A 5.2 Roles and Responsibilities

Mistakes People Make

In my experience, the top 3 mistakes people make for ISO 27001 Annex A 5.1 are

You have no evidence that anything actually happened

You need to keep records and minutes of everything. You need a paper trail to show it was done. Make sure you have updated communication plans, minutes of meetings, records of acknowledgement, records of approval. If it isn’t written down it didn’t happen.

One or more members of your team haven’t done what they should have done

Prior to the audit check that all members of the team have done what they should have. Do they know where the policies are? Have they acknowledged them? Did someone join last month and forget to do it? Check!

Your document and version control is wrong

Keeping your document version control up to date, making sure that version numbers match where used, having a review evidenced in the last 12 months, having documents that have no comments in are all good practices.

ISO 27001 Templates

Changes and Differences to ISO 27002:2013

While the 2022 version of ISO 27001 retains many similarities to its predecessor, distinctions emerge:

Control 5.1 “Information Security Policies” in ISO 27001:2022 consolidates two controls (5.1.1 and 5.1.2) from the 2013 version. While the core principle remains the same – establishing and maintaining an information security policy – the 2022 version provides a more comprehensive and structured approach.

Key Enhancements in ISO 27001:2022

• Expanded Guidance: Control 5.1 now includes a detailed description of its purpose and expanded implementation guidance.
• Attributes Table: The inclusion of an attributes table facilitates easier mapping of controls to industry-specific terminologies.
• Enhanced Requirements: The policy requirements are more comprehensive, encompassing:
  • Clear definition of information security.
  • Establishment of information security objectives.
  • Commitment to continuous improvement of the ISMS.
• Redefined Topic-Specific Policies: The scope of topic-specific policies has been revised, with a focus on key areas like incident management, asset management, and secure development.

Key Differences

Consolidation of Controls: The 2013 controls for “Policies for Information Security” and “Review of Policies for Information Security” are merged into a single control in the 2022 version.

Emphasis on Regular Review: The 2022 version explicitly emphasises the need for regular policy reviews, particularly in response to changes in the information security environment.

Comprehensive Policy Requirements: The 2022 version includes more detailed requirements for the information security policy, such as a commitment to continual improvement.

Overall, Control 5.1 in ISO 27001:2022 provides a more robust and comprehensive framework for establishing and managing information security policies within an organisation.
