What are ISO 27001 Policies?
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.
Policies are a foundation stone of an information security management system. They are approved by senior management and outline an organisation’s approach to safeguarding sensitive data. Furthermore, they include both high-level and low-level guidelines, ensuring that all employees understand their responsibilities in maintaining data confidentiality, integrity, and availability. Subsequently, policy reviews, stakeholder communication, and a formal change management process are crucial for maintaining the effectiveness of this critical element of an organisation’s information security management system.
Basically they are intended to ensure the ongoing suitability, adequacy, and effectiveness of management direction and support for information security, aligning with all applicable business, legal, statutory, regulatory, and contractual requirements.
ISO 27001 Policy Templates
ISO 27001 policy templates are a fast track that are guaranteed to save you time and money. ISO 27001 Annex A 5.1 Policy templates are focused on the ISO 27001 Policies and having an ISO 27001 Policy Pack. The benefit of using the ISO 27001 policy pack is that the ISO 27001 templates are already fully populated and ready to go.

What is ISO 27001 Annex A 5.1?
ISO 27001 Annex A 5.1 Policies for Information Security is an ISO 27001 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.
Purpose & Definition
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.
The ISO 27001 standard 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.
ISO/IEC 27001:2022 Annex A 5.1 Policies for Information Security
Reference Guide
In this ISO 27001 Policies Ultimate Guide I show you what the requirement is for ISO 27001 and the detailed requirements for the new ISO 27001 standard of controls.
The following is compliance guidance for Policies for Information Security.
Guidance
Organisations must have an information security policy approved by top management. This policy outlines the organisation’s approach to managing information security. Implementing ISO 27001 Annex A 5.1 requires a structured approach to defining, approving, and communicating the rules that govern your information security environment. This roadmap outlines a pragmatic process for implementing Annex A 5.1, ensuring a clear evidence trail for your auditor.
Senior leadership ownership
Designate the senior leadership team as the primary body responsible for developing, approving, and implementing information security policies. The result is a governance framework where policies carry sufficient corporate authority to drive compliance across all departments.
- Appoint a Policy Owner from the executive board to maintain ultimate accountability.
- Define the roles of the Senior Leadership Team in the formal approval process.
- Ensure resource allocation is provided for policy enforcement and monitoring.
Core policy requirements
Align the policy suite with specific business strategies, legal obligations, and security risks. The result is a robust set of rules that protects the organisation’s specific business needs while ensuring full compliance with relevant laws, regulations, and contracts.
- Map strategies to ensure security supports rather than hinders business growth.
- Integrate contractual obligations from enterprise clients into the policy language.
- Cross-reference the Risk Register to ensure policies address current and potential threats.
Comprehensive policy statements
Include clear statements that define information security and establish security objectives for the organisation. The result is a documented set of guiding principles and frameworks that commit the organisation to continuous improvement and clear responsibility mapping.
- Outline principles for all information security activities to ensure consistency.
- Establish procedures for handling exceptions to prevent security “shadow IT.”
- Include formal commitments to meeting all applicable statutory security requirements.
Topic specific policies
Develop detailed guidance for specific security controls such as Access Control, Physical Security, and Asset Management. The result is a modular policy architecture that supports the main information security policy with granular, actionable rules for technical teams.
- Provision specific policies for Network Security, Cryptography, and Data Classification.
- Ensure topic-specific rules align with Secure Development and Vulnerability Management.
- Establish clear directives for Device Security and Data Transfer to protect remote workers.
Top management approval
Obtain formal approval from top management for all primary policies and any subsequent changes. The result is a physical or digital evidence trail that satisfies ISO 27001 Clause 5.2 requirements for leadership commitment.
- Record approval in signed minutes of Information Security Management meetings.
- Utilise digital signatures for version control and non-repudiation.
- Ensure the CEO or equivalent role has personally validated the top-level policy.
Communicate and track acknowledgement
Disseminate policies to all personnel and stakeholders in an understandable format and require formal acknowledgement. The result is a legally defensible record that staff have read, understood, and agreed to comply with security mandates.
- Execute a communication plan that makes policies accessible via a central Intranet or portal.
- Redact or protect confidential information when distributing policies to external parties.
- Retain digital sign-off evidence through a Learning Management System or email confirmation.
Regular policy reviews
Review the policy set at planned intervals or following significant changes to technology or business strategy. The result is an adaptive ISMS that incorporates lessons learned from security incidents and findings from internal audits.
- Schedule annual reviews led by personnel with the necessary technical expertise.
- Assess policy relevance against evolving security risks and updated legal contracts.
- Ensure management reviews directly inform the policy update process for continual improvement.
Supplementary Guidance
Topic-specific policies can vary across organisations.
| Information security policy | Topic-specific policy | |
|---|---|---|
| Level of detail | General or high-level | Specific and detailed |
| Documented and formally approved by | Top management | Appropriate level of management |
How to implement it
Implementing this control requires a structured approach to writing and deploying policies and making sure that they are enforced. The high level implementation process is:
- work out what policies you actually require
- write them
- sign them off
- publish them
- have them acknowledged by staff
- review them at regular intervals
This roadmap outlines a pragmatic process for implementing Annex A 5.1, ensuring a clear evidence trail for your auditor.
Step 1: Determine Required Policies
Identify the policies your organisation requires based on your Statement of Applicability, business risks, and legal obligations. Avoid a “one-size-fits-all” approach; if you do not develop software, you do not need a secure development policy.
Step 2: Write the Policies
Draft the main policy and necessary topic-specific documents. Remember: policies state what you do, not how you do it (the “how” belongs in procedures). Keep them concise and principle-based.
Step 3: Assign Ownership
Designate an owner for every policy. While an Information Security Manager may draft the content, senior leadership must retain ultimate accountability to ensure the policy carries authority.
Step 4: Secure Management Approval
Crucial Step: Top management must formally approve all policies. Record this evidence in signed minutes of information security management meetings.
Step 5: Publish and Communicate
Publish policies in an accessible location (e.g., Intranet). Execute a communication plan to ensure all personnel are aware of the policies; a single email is insufficient.
Step 6: Get Acknowledgement
Retain evidence that personnel have read and understood the policies. Methods include email confirmations, signed forms, or LMS digital sign-offs.
Step 7: Schedule Regular Reviews
Review policies at planned intervals (at least annually) or upon significant changes (e.g., new technology or legal requirements). Document these reviews in version control logs.
How to comply
To comply with ISO 27001 Annex A 5.1 Policies for Information Security 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 auditor 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
Top 3 mistakes and how to avoid them
In my experience, the top 3 mistakes people make for ISO 27001 Policies for Information Security are
1. 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.
2. 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!
3. 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 Annex A 5.1 FAQ
ISO 27001 does not specify a fixed number of policies, but organisations typically require between 15 and 25 topic-specific policies to address identified risks. The list of policies you need can be found here in the High Table Ultimate Guide to ISO 27001 Policies. You decide what policies you need by first completing your ISO 27001 Statement of Applicability and then identify in conjunction with the ISO 27001 standard the required policies for your implementation. Examples of support ISO 27001 policies include Access Control Policy, Data Classification Policy, Incident Response Policy, Remote Access Policy, Bring Your Own Device (BYOD) Policy, Email Security Policy, and Social Media Policy.
The primary purpose is to establish a framework for managing information security within an organisation: it outlines the organisation’s commitment to protecting its information assets from various threats. The key elements of an information security policy are:
Scope: Defines the boundaries of the policy, such as which parts of the organisation and types of information.
Objectives: States the desired outcomes of the information security program, including confidentiality, integrity, and availability.
Responsibilities: Clearly defines the roles and responsibilities of management, employees, and other stakeholders.
Compliance: Outlines compliance with relevant laws, regulations, and standards, for example, GDPR or PCI DSS.
ISO 27001 Annex A 5.1 will take approximately 3 months to complete if you are starting from nothing and doing it yourself, whereas a template bundle can reduce this to less than 1 day. There are policy templates for ISO 27001 Annex A 5.1 located in the High Table ISO 27001 Policy Templates Toolkit. All of the ISO 27001 Policies have free, example PDFs that you can download in the High Table ISO 27001 Policy Templates Toolkit. While the work is not technically hard, doing it yourself involves a high lost opportunity cost compared to a toolkit cost of a few hundred pounds or dollars.
The senior leadership team is responsible for the information security policies as they set the direction and agree on what must be done. ISO 27001 Annex A 5.1 Information Security Policies is important because people need to know what is expected of them. Policies are statements of what you do: they are not statements of how you do it. From a HR perspective, you have no come back if someone does something wrong unless you have told them what they should do right and the consequences for getting it wrong. No matter how common sense you think it is, someone will disagree unless you have told them.
Policies must be communicated in a clear, accessible format via channels like the Intranet, email, workshops, or employee handbooks. Recipients should acknowledge their understanding and agreement to comply. Integrating policies into business processes is achieved by developing standard operating procedures (SOPs), providing regular training, and conducting audits to monitor compliance. To ensure employee understanding:
Require employees to sign acknowledgement forms.
Incorporate policy awareness into training programs.
Use online training modules with quizzes to test understanding.
Policies should be reviewed at least annually, or more frequently if there are significant changes such as new technologies or regulatory updates. ISO 27001 Annex A 5.1 is the information security control requirement for certification, while ISO 27002 Control 5.1 provides the implementation guidance. Benefits of having this framework in place include a reduced risk of data breaches, improved compliance, and increased employee awareness. Violating a policy may lead to disciplinary action: consequences range from warnings to termination of employment, depending on the severity.
