ISO 27001 ISMS
The information security management system (ISMS) is how you manage information security and is made up of documents and processes. We are going to look at what a management system is and how to build it.
In this ultimate guide to ISO 27001 Clause 4.4 Information Security Management System you will learn
- What the ISO 27001 ISMS is
- How to implement an ISO 27001 ISMS
- ISO 27001 ISMS templates you can use
I am Stuart Barker, the ISO 27001 Ninja and author of the Ultimate ISO 27001 Toolkit.
With over 30 years industry experience I will show you what’s new, give you ISO 27001 templates, show you examples, do a walkthrough and show you how to implement it for ISO 27001 certification.
What is an ISMS?
An information security management system (ISMS) is a combination of policies, processes, systems and people that ensure the confidentiality, integrity and availability of data.
ISO 27001 is a risk-based system. It’s a system based on understanding what the risks are to you and your organisation and then implementing controls to mitigate those risks.
The management system element itself is about how you organise yourself, how you manage and how you deliver the information security management.
What does an ISMS include?
The Information Security Management System (ISMS) includes
- ISO 27001 Mandatory Documents
- ISO 27001 Policies
- ISO 27001 Controls
- ISO 27001 Processes and Procedures
What is an ISO 27001 ISMS?
ISO 27001 Clause 4.4 is the Information Security Management System. It requires an organisation to have an information security management system that is established, implemented and continually improved.
An ISO 27001 ISMS is made up of the ISO 27001 documents, ISO 27001 policies and processes that deliver your information security controls and keeps you safe.
Part of ISO 27001 Clause 4 Context of Organisation this is the fourth requirement. It builds upon
- ISO 27001 Understanding the Organisation and its Context where we define internal issues and external issues that could impact the information security management system.
- ISO 27001 Understanding the Needs and Expectations of Interested Parties where we captured and addressed the needs of stakeholders in our information security management system.
- ISO 27001 Determining the Scope of the Information Security Management System where we defined what aspects of our organisation were to be covered.
So we know what could impact it, what people want from it, what it will be applied to and now we look at the actual information security management system itself.
ISO 27001 ISMS Purpose
The purpose of the ISO 27001 ISMS is to make sure you have an actual information security management system in place and that it is established, implemented and continually improved.
ISO 27001 ISMS Definition
The ISO 27001 standard defines the ISO 27001 Information Security Management System as:
The organisation shall establish, implement, maintain and continually improve an information security management system, including the processes needed and their interactions, in accordance with the requirements of this document.
ISO 27001:2022 Clause 4.4 Information Security Management System
ISO 27001 ISMS Requirement
The requirement of the ISMS is to have in place a management system for information security.
The standard wants you to establish, implement and continually improve your information security management system and to have in place the required processes.
Follow the ISO 27001 standard and implement the clauses as well as the applicable annex a controls and you will meet the requirement.
Implementation Options
Write it yourself
To write a management system yourself you would require some knowledge and some experience. The approach you would take would be
- purchase a copy of the standard
- review all of the ISO 27001 clauses that make up the standard
- work out what the documentation is that you require
- create that documentation
Buy a Toolkit
If you purchase an ISO 27001 Toolkit you will get all of the mandatory documents, training, support and knowledge as well as a proven management system based on best practice to fast track your implementation.
Engage a consultant
Consultants are a great option to create a bespoke management system when cost is not an issue.
Implementation Guide
General Guidance
Being so broad brush what this clause is actually saying is – implement the ISO 27001 standard. In reality that is the information security management system. So if you go through all of the requirements of ISO 27001 and satisfy them, you will have an information security management system and you will satisfy this clause.
Sounds easy. And it is. It just takes a time. A lot of time. Especially if you have never done it before. Luckily, we have.
Understand business needs
Understanding business needs, you want to make sure your information security management system meets the needs of the business.
Before you build and implement an ISMS, it’s important for organisations to understand who they are, what they have and what their needs are. Write into the standard document the who and what of your organisation before you look start your ISMS.
Define the Scope of the ISMS
Define the scope of the information security management setting out what it will cover. Consider systems, processes, people, premises and technology and document what is in and what is out of scope.
Write and implement policies
Policies are statements of what you do and communicate what is expected. You will implement policies that are specific to your organisation. Policies are a foundation stone of an effective management system.
Policies are statements of what you do, not how you do it. The first step is to agree as a business what it is you actually do do or want to do. You can follow the How To Build and Implement Policies Guide.
Train People
You will train people and ensure that you educate them and implement a culture of information security.
Conduct security awareness training. All employees should receive regular security awareness training. This is the first line of defence and we want to train people on information security and data protection.
Secure Devices
You are going to secure devices and technology.
Devices need to be known and in an asset register. Those devices then need protecting with antivirus, encryption and regular patch management.
Backup
You are going to make sure that you put in backups. You will back up a lot and test that you can recover from back up.
Back up data. Backups play a key role in preventing data loss and should be a part of a company’s security policy before setting up an ISMS. Like insurance, the value will not be obvious until the time you come to need it.
Continually Improve
Your management system will continually improve. Continual improvement is baked into the standard. Your information security management system has to have the ability to continue to improve and there are a number of steps and processes in future blogs that will go through that.
An ISMS is not a one and done. It is an ongoing process of continual improvement and enhancement. Always getting better.
Audit Yourself
You’re going to continually audit and audit is going to be part of your life.
The management system has built into it internal audit.
You are going to be continually naval gazing and reviewing yourself and doing your internal audits against the standard ISO 27001 and against the annex a controls.
The process of internal audit is ongoing and you’re going to get externally audited a lot.
When you have defined what you do and how you do it, it is best practice to check it. This is the process of internal audit. Looking and checking to see that things are working as intended and fixing things that are not.
Design for audit
Design your management system how I have the toolkit. You want to create documents that you are asked for on a regular basis.
It is a misconception that by having ISO 27001 certification third party questionnaires and external audits will end. They won’t.
When you build your management system build it in a way that is effective and efficient for you to manage but also for you to respond to third party questionnaires and to those third party audits. It’s going to make your life so much easier.
ISO 27001 Toolkit
To implement ISO 27001 Clause 4.4 you need to get a copy of the Ultimate ISO 27001 Toolkit and implement it using the proven implementation methodology and step by step implementation blue print.

ISO 27001 ISMS Templates
ISO 27001 clause 4.4 ISMS is actually a series of ISO 27001 templates that we have collated into the ISO 27001 Toolkit. Designed specifically for those wanting to do it themselves and save both time and money in the process.
ISO 27001 templates have the advantage of being a massive boost that can save time and money so before we get into the implementation guide we consider these pre written templates that will sky rocket your implementation.
I created the Ultimate ISO 27001 Toolkit to fully meet clause 4.4 and it has been used thousands of times, globally, to get clients ISO 27001 certified.
How to pass the audit
To pass an audit of ISO 27001 Clause 4.4 ISMS you are going to establish, implement and continually improve your information security management system and to do that you would be best placed to get a copy of the ISO 27001 toolkit.
What the auditor check
The auditor is going to check a number of areas for compliance with Clause 4.4 ISMS. Lets go through them
1. That you have a documented information security management system
The simplest way to do this is to download the ISO 27001 Toolkit.
2. That you can evidence the effective operation of the information security management system
Once you have your information security management system in place the audit is going to look for evidence of the effective operation. This means having records of activity. Examples are having meeting minutes for the management review team, the risk register, risk reviews, continual improvement, incident management. What you say you do, you should be able to evidence.
3. That you are continually improving
Not everything will be perfect and not everything will work 100% of the time. When things go wrong you will have incident management that may lead to continual improvement. When you conduct internal audits you may find things not working as expected that may lead to continual improvements. External audits may find things that require continual improvement. Risk management may also lead to continual improvement. Be prepared to evidence your continual improvement and the associated records.
Top 3 ISMS Mistakes People
These are the top 3 mistakes that organisations makes for ISO 27001 Clause 4.4 ISMS that will costs you thousands:
1. Buying a portal or web based tool
A portal may well be a great investment in time to help the information security manager to do their job but there is a lot of cost involved in going this route and the work that is required, still needs doing. This is a cost on top of the cost of ISO 27001 implementation. Extra cost. When the time is right, consider it but it is our experience for the novice or beginner these tools will only complicate matters and increase your costs exponentially.
2. Doing it yourself with no help at all
It is not complicated but there is a lot to cover. Even if you just watch our ISO 27001 YouTube how to’s or follow this free how to implement ISO 27001 guide you will be better placed for the journey ahead. Assuming you can do it with zero knowledge will lead to expensive mistakes and expensive rework.
3. Giving it to IT to sort out
ISO 27001 is a management system that covers the entire business. Whilst there are elements of IT, this is NOT an IT standard or IT solution. It requires business leadership and business buy-in. Give it to IT, and you are doomed to fail.
ISMS Relevant Standards
There are many standards that are relevant to the ISMS.
The ISO/IEC 27000 family of standards
The ISO/IEC 27000 family are the most well known of the standards governing information security management and the ISMS and are based on global best practice opinion. Widely adopted in business and a minimum standard for information security. They lay out the requirements for best practice – “establishing, implementing, deploying, monitoring, reviewing, maintaining, updating, and improving information security management systems.”
The ITIL framework
ITIL acts as a collection of concepts, policies, and best practices for the effective management of information technology infrastructure, service, and security.
The COBIT framework
COBIT, developed by ISACA, is a framework for helping information security personnel develop and implement strategies for information management and governance while minimising negative impacts and controlling information security and risk management.
ISO 27001 ISMS FAQ
They now refer through the standard to this ‘document’ rather than this ‘international standard’. So replace the words ‘international standard’ with the word ‘document.
They have added into the sentence the term – ‘including the processes needed and their interactions’ to be absolutely crystal clear that processes are included, rather than implying it.
In essence, nothing has changed. It is clarification of wording.

The purpose of an Information Security Management System (ISMS) is to minimise risk to the confidentiality, integrity and availability of data.
Ultimately is wants to prevent a data breach and ensure your business can operate uninterrupted.
Confidentiality: making sure data can only be accessed by authorised people.
Integrity: keeping data accurate and complete.
Availability: making sure data can be accessed when it’s required.
The responsibility for the operation of the information security management system is usually the information security professional. It takes someone with knowledge and experience to run. It isn’t hard or complicated and can be learnt. You can even do it yourself with the ISO 27001 toolkit. Although operationally it is usual to have an information security professional run it.
The Information Security Management System (ISMS) is based on risk and business need. As such, the level of controls that are chosen and implemented are directly related to that business risk. In addition, the ISMS is influenced by the organisation’s needs, objectives, security requirements, size, and processes.
To be effective an ISMS will include a process of continual improvement, a process of incident management and a process of on going internal audit.
Other than your ISO 27001 certification requiring it, the following are the top 5 benefits of an Information Security Management System (ISMS):
You cannot get ISO 27001 certification without it.
Improved security: You will have an effective information security management system that addresses common information security risks
Reduced risk: You will reduce the information security risks by identifying those risks and addressing them
Improved compliance: Standards and regulations require an effective information security management system to be in place
Reputation Protection: In the event of a breach having an effective information security management system in place will reduce the potential for fines and reduce the PR impact of an event
As mentioned in the top 5 benefits of an ISMS, you cannot get ISO 27001 certification without it. You need it. The ISMS will bring with it consistency and maturity of processes where you will document what you do and evidence that you do it. This will give you maturity in process where outcomes are determined by process and not by who did it on the day. With documented processes you future proof your organisation and remove the reliance on individuals that could hurt your business if they left. It removes the single point of knowledge failure.
The goal of an Information Security Management System (ISMS) isn’t necessarily to maximise information security, but rather to reach an organisation’s desired level of information security based in need and risk. Depending on the specific needs these levels of control may vary from one organisation to the next
ISO/IEC 27001 is the international standard for information security but the standard doesn’t mandate specific controls. Instead it provides a list of controls, referred to as ISO 27001 Annex A, for the organisation to consider for appropriateness. You will create your statement of applicability showing which controls you have implemented based on business risk and business need.
For your management system you will includes documentation, internal audits, continual improvement, and corrective and preventive action. To become ISO 27001 certified, an organisation needs an ISMS that identifies the organisation’s assets and provides the following assessment:
the risks the information assets face
the steps taken to protect the information assets
a plan of action in case a security breach happens
identification of individuals responsible for each step of the information security process
The ISMS should be monitored and reviewed on a regular basis to ensure that it is operating effectively. This includes:
Measures and Monitoring of the security controls.
Conducing and reviewing the risk assessment.
Conducting internal audits
Getting feedback from interested parties
The challenges of implementing an ISMS will vary based on your size and complexity with some common challenges being:
Lack of resources
Lack of time
Lack of expertise
Cost
