ISMS 27001

A Guide to ISMS Information Security Management System

Posted by: TÜV SÜD Expert Date: 05 Sep 2023

Information is one of the most valuable resources available for businesses today. And as data emerges as the world's new currency, cybercrime is on the rise. 83% of global organisations have experienced more than one data breach, and the average global cost of cybercrime is around $6 trillion annually. 

As a result of this rising prevalence of hacks and cyberattacks across the globe, modern business organisations must implement stringent information and data security systems that can protect their information assets.

And this is where ISO/IEC 27001 ISMS can make a difference. But what is an ISMS?

Let's explore the significance of ISMS, how it bolsters security, and how to establish an effective ISO/IEC 27001 ISMS.

What Are ISO/IEC 27001 and ISMS?

ISMS stands for Information Security Management System, and ISO/IEC 27001 can be tailored to meet the organisational needs for managing and protecting information assets.   

ISO/IEC 27001 prescribes detailed requirements to help you establish, implement, maintain, and continually improve an ISMS within your organisation. It also includes requirements for the assessment, and treatment of information security risks.

The ISO/IEC 27001 ISMS requirements apply to every organisation that handles, stores and processes information in all forms.   

Latest Updates to ISO/IEC 27001

ISO/IEC 27001:2022 is the latest version of the international standard, the third edition published in 2022. The latest version has undergone minor changes in the clauses without changing the intent of the requirements, however; the Annex A of the standard, which contains the control requirements, has undergone a structural change with some new control additions. To ensure your Information Security Management System (ISMS) aligns with current industry best practices and protects against evolving threats to information security, it's essential to both reference and implement the latest version of ISO/IEC 27001. 

What Components Comprise the ISMS in ISO/IEC 27001? 

The three key pillars   of information security are confidentiality, integrity, and availability of information. 
The components of ISMS include assets, objectives, policies, procedures, resources and controls. These components should interact seamlessly in order to build a robust ISMS. The ISMS will help organisations to do the following: 

  • Identifying relevant interested parties   and their information security expectations.
  • Identifying information security risks and addressing them by establishing and implementing risk treatment plans with appropriate controls    
  • Setting clear information security objectives and plans to achieve them.  
  • Monitoring and measuring the information security processes and controls and also evaluating the performance of ISMS.  
  • Continually improve the policies, procedures, controls, and other ISMS components   to ensure a high-performing ISMS.

What Are the Requirements in ISO/IEC 27001?

When developing and implementing an ISMS in compliance with ISO/IEC 27001, every interested organisation is required to determine the following:

Organisation Context

Identifying and defining issues (internal and external) that are relevant to the organisation’s context that influence the organisation’s business and objectives.

Interested Party Needs

Requirements and expectations of the interested parties that need to be addressed through the ISMS.


Boundaries and applicability of the ISMS.

Risk Assessment

Identifying, analysing and evaluating information security risk.

Risk Treatment

Implementation of controls necessary to treat and mitigate the identified information security risks.


Measurable and relevant information security objectives that are clearly documented and communicated with the team, constantly monitored, and periodically updated.


Establishing the necessary competence of the personnel that may affect information security performance.


Ensuring all personnel working with the organisation know and understand the information security policy and their contribution to ISMS effectiveness.


Clear communication with internal and external stakeholders.

Documented Information

Maintain and retain documented information as required by the standard and the organisation.


Implementing processes, including controlling outsourced processes and managing changes. Performing risk assessment and risk treatment periodically and when significant changes occur.

Internal Audit

Regularly planned internal audits to ensure ISMS compliance with organisational information security requirements and ISO/IEC27001 requirements.

Management Review

Regularly planned review of the ISMS by top management to ensure its suitability, effectiveness, and adequacy.


Continual improvements to the ISMS by implementing effective corrective and preventive actions for detected and potential non-conformities, respectively. Additionally, new controls can be implemented to safeguard against emerging risks, thereby enhancing the overall performance of the ISMS.

Why Invest in Information Security Management System (ISMS) Training Based on ISO/IEC 27001 International Standard?   

Investing in an ISMS offers the following advantages:

  • It provides a structured framework to guide strategies and practices to achieve information security effectively. This includes requirements   for establishing information security rules, roles, and responsibilities of individuals and safeguarding controls, making it easier to manage complex systems.
  • A well-defined ISMS means interrelated information security processes, which translates to fewer security incidents and better information security of assets within an organisation. Additionally, you can also address potential risk events before they cause issues like data breaches, reputational damage, or financial losses.
  • An ISMS can save you money in the long run by ensuring you follow regulations, lowering insurance expenses, and reducing the costs linked to data breaches.  
  • ISMS training can enhance client, partner, and stakeholder trust and credibility. This can lead to stronger business relationships and increased customer loyalty and help you gain a competitive edge.
