ISO 27001 is of little help
In deciding what to monitor and measure regarding your Information Security Management System (ISMS), ISO 27001 specifies no mandatory requirements (as emphasised in our ISO 27001 training courses). Thankfully, ISO 27004 provides guidelines and principles for measuring and reporting the effectiveness of an organisation's ISMS. The standard helps organisations to evaluate information security management processes, identify weaknesses, and take corrective actions.
This article will explore ISO 27004 and the importance of measuring information security effectiveness.
What is ISO 27004?
This standard provides guidelines and best practices for measuring the effectiveness of an ISMS. The standard is designed to help organisations evaluate their security posture, identify gaps in security measures, and take corrective actions. ISO 27004 is part of the ISO 27000 family of standards, which includes the widely recognised ISO 27001 standard for ISMS.
The ISO 27004 standard covers the following areas:
1. Establishing a framework for measuring information security effectiveness
2. Developing and implementing measurement methods
3. Collecting and analysing data
4. Reporting and communicating information security effectiveness
Why is measuring information security effectiveness important?
Measuring information security effectiveness is crucial for organisations to identify potential risks and vulnerabilities in their systems and processes. In addition, it allows them to identify areas for improvement and take corrective actions before a security breach occurs. Measuring effectiveness can also help organisations to demonstrate compliance with regulatory requirements, such as GDPR and HIPAA.
Additionally, measuring information security effectiveness helps organisations to:
1. Understand the effectiveness of their security measures
2. Evaluate the return on investment (ROI) of security initiatives
3. Demonstrate the value of information security to stakeholders
4. Identify and prioritise areas for improvement
5. Continuously improve the organisation's security posture

How to measure information security effectiveness?
ISO 27004 guides how to measure information security effectiveness. The standard recommends the following steps:
1. Define the scope and objectives of the measurement process
2. Identify and prioritise the assets and processes to be measured
3. Develop measurement methods and metrics
4. Collect and analyse data
5. Report and communicate the results
Measurement methods can include both quantitative and qualitative approaches. For example, quantitative methods can involve collecting data on the number of security incidents, the time to detect and respond to incidents, or the effectiveness of security controls. Qualitative methods can include surveys, interviews, or focus groups to gather information on security awareness, training, and culture.
Now it's your turn!
Measuring information security effectiveness is essential for organisations to evaluate the effectiveness of their information security management system, identify areas for improvement, and take corrective actions. The ISO 27004 standard provides guidelines and best practices for measuring information security effectiveness. By following these guidelines, organisations can continuously improve their security posture and protect their assets and data from potential threats.
deGRANDSON Global is an ISO Certified Educational Organization
October 2021, we secured certification to three education-related ISO Standards. As a result, we now have a university-grade management system in place conforming to the requirements of …
- ISO 21001, Educational Organizational Management System,
- ISO 29993, Learning Services outside formal Education, and
- ISO 29994, Learning Services – additional requirements for Distance Learning.
We have chosen ISO 21001 certification because, unlike IRCA and Exemplar badges (which, in our opinion, are commercially compromised), it is based on independent third-party assessment. In addition, it is a ‘university grade’ standard in use globally by schools, colleges, and universities to demonstrate their competence.
