Many articles are available to teach you about the world of ISO 27001, covering what compliance certification offers and how it can elevate a company’s ISMS. However, have you wanted to know how the compliance measure achieves such greatness?

ISO certifications are world-renowned compliance measures that reduce risk and enhance safety within operating systems. When asked what ISO 27001 is and how it achieves such brilliant results, our answer is always hinged on the award focus on the people, processes, and technology. These three pillars offer a recipe for success, but just like any great meal, the entire result can change if one component is not quite right. They also ensure that the cost of an ISO 27001 certification can be justified for organisations of all sizes.

Continue reading to learn how ISO 27001 achieves cyber safety for ISMS of all sizes and specifications.

What Is The Purpose of ISO 27001?

ISO 27001 (Information Security) is a global certificate of excellence in Information Security Management. Designed to protect ISMS by creating succinct processes, using the best technology and educating users, the award is a popular choice regarding data management and reducing cyber security spending.

Businesses with this accreditation can work more confidently by promoting a constant awareness of Information Security Management Systems. The parameters are also ideal for hybrid working companies, which are more likely to experience data violations due to various networks that could be used.

You will likely have heard of some other forms of compliance measures and be wondering how ISO 27001 is different. If you want to know if Cyber Essentials is the same as ISO 27001, you will see the main variations in the control measures that ISO requires organisations to adopt. ISO 27001 and other awards from compliance experts are designed to embed safe operations in every inch of a company’s operating infrastructure. Whereas some other awards may focus on software, people, or processes, ISO 27001 aims to unite all factors into one concise form of security management that achieves the best protection possible.

This clearly shows that ISO 27001 can’t be outdated as it constantly evolves and changes with the latest threats. In summary, the purpose is to protect critical information assets through compliance excellence.

How Does ISO 27001 Work to Protect ISMS?

How Does ISO 27001 Work to Protect ISMS?

Now, for the reason that you have clicked on this article, how does ISO 27001 work?

The simple answer is that ISO 27001 can protect ISMS by establishing a framework of controls and requirements that allow full management of the entire network. This network is security enriched and configured to highlight any risks, provide the solution for fixing, and make successful adaptations without exposing any data. The success is made up of the controls and requirements that the certification requires full compliance with.

ISO 27001 consists of 114 controls, of which seven are deemed as requirements to adopt for being formally awarded a compliance certificate. A company that doesn’t meet the following controls will not pass audits. It’s as simple as that. The complexity of the tasks associated with the controls and requirements also demonstrate why it can take up to a year to obtain ISO 27001 as processes must be robust and tested before they are passed.

The requirements of ISO 27001, which explain how ISO 27001 works, are as follows:

  1. A Defined ISMS Project Scope

An ISMS Scope documents a particular business’s requirements and the contributing factors that need to be managed to create the project scope. This can be seen as the master document, referred to at any point of ISO compliance. As the solid groundwork on which ISO measures are created this ensures everyone has the same understanding of a company’s ISMS, eliminating risks and the chance of breaches.

  1. Commitment from Leadership

All business leaders must have acknowledged the ISO structure and ISMS policies. In this sense, ISO 27001 works by ensuring everyone has the same shared understanding.

  1. Defined Security Objectives

Another example of how ISO 27001 works is my defining an order of priority for security risks. No matter the security objectives, they will then be published within the organisation as they form the more comprehensive security measures required to be put into place. By knowing what security risks apply to the ISMS, a business can tackle the problem more diligently and efficiently.

  1. Resource Planning

This requirement facilitates a secure ISMS by ensuring teams are trained and aware of their responsibilities.

  1. Operations and Strategy Published Procedures

This requirement outlines that businesses should produce a risk assessment procedure and a published calendar for when assessments will be carried out. By providing a direct representation of how ISO measures work for an individual business, the structure provided constantly encourages investigation, assessment, and resolution.

  1. Performance Measurement Outlines

Another way that ISO works is by tracking performance to show if processes are working correctly as time passes. This is facilitated via published procedures for tracking and assessing the ongoing ISMS performance and adherence to the broader ISO 27001 control measures.

  1. Nonconformity Management Process

Last but not least is requirement seven which requires companies to showcase a solid nonconformity procedure. This works to reduce risk and strengthen disaster recovery as issues can be picked up and resolved efficiently.

ISO also works by outlining controls needed for the various aspects of business. By covering all departments and operations, ISO 27001 is able to facilitate ISMS across an entire business. The controls are as follows:

  • Information Security Policies (2 Controls)
  • Organisation of Information Security (7 Controls)
  • Human Resources Security (6 Controls)
  • Asset Management (10 Controls)
  • Access Control (14 Controls)
  • Cryptography (2 Controls)
  • Physical and Environmental Security (15 Controls)
  • Operational Security (14 Controls)
  • Communications Security (7 Controls)
  • System Acquisition, Development, and Maintenance (13 Controls)
  • Supplier Relationships (5 Controls)
  • Information Security Incident Management (7 Controls)
  • Information Security Aspects of Business Continuity (4 Controls)
  • Compliance (8 Controls) (These controls also feature various customer management elements which essentially mean that ISO 27001 also covers GDPR.)

By combining all requirements and controls into a concise and audited structure, ISO 27001 facilitates daily operations, business scaling, stakeholder changes, and security risk management with one master process.

What Role Do Audits Play In The Success of ISO 27001?

We couldn’t talk about how ISO 27001 works without including something about audits. They may seem like a chore, but these investigative looks at the ISMS frameworks are the aspect of ISO that ensures everything is working as it should be.

For many, ISO 27001 is required as a way to unite operations. The audits carry out the testing and enquiry part of the process pillar but require a constant view to be obtained of performance. In this sense, ISO 27001 can be explained as working through a continual process of understanding and resolution. This also highlights one of the main differences between ISO 27001 and Cyber Essentials, as ISO works by constantly assessing processes. At the same time, Cyber Essentials uses the same structure for the duration of the certification.

Does the Implementation Phase Affect How Well ISO 27001 Can Work?

Does the Implementation Phase Affect How Well ISO 27001 Can Work?

Yes, it certainly does!

ISO doesn’t require penetration testing, but it is advised to test an ISMS’s robustness. This is just one example of how ISO 27001 works to protect sensitive information from hackers. If this has been successfully configured during the implementation phase, the processes will be able to work more efficiently and garner better results further down the line.

How Can Create Networks Support ISO 27001?

Hopefully you now understand how ISO 27001 works to protect ISMS. The configuration and management can be complex so working with a team of experts, such as our own, is a great idea.
