What is ISO 27001?
ISO/IEC 27001:2013 (also known as ISO27001) is the international standard that describes best practice for an ISMS (information security management system).
Achieving accredited certification to ISO 27001 demonstrates that your company is following information security best practice and provides an independent, expert verification that information security is managed in line with international best practice and business objectives.
ISO 27001 is supported by its code of practice for information security management, ISO/IEC 27002:2013.

ISO 27001 and ISO 27002 2022 updates
ISO/IEC 27001:2022 – the newest version of ISO 27001 – was published in October 2022.
Organisations that are certified to ISO/IEC 27001:2013 have a three-year transition period to make the necessary changes to their ISMS (information security management system).

What is an ISMS?
An ISMS is a systematic approach consisting of processes, technology and people that helps you protect and manage all your organisation’s information through effective risk management.
At the heart of an ISO 27001-compliant ISMS are business-driven risk assessments, which means you will be able to identify and treat security threats according to your organisation’s risk appetite and tolerance.

ISO 27001 clauses and controls
ISO 27001 has ten management system clauses. Together with its control set from Annex A (which lists 114 controls), they support the implementation and maintenance of an ISMS, as shown in the infographic below.
- Normative references
- Terms and definitions
- Planning and risk management
- Performance evaluation
ISO/IEC 27001: 2013 controls
The Standard doesn’t mandate that all 114 controls be implemented. Instead, the risk assessment should define which controls are required, and a justification provided as to why other controls are excluded from the ISMS.
Below are the list of control sets.
- A.5 Information security policies
- A.6 Organisation of information security
- A.7 Human resource security
- A.8 Asset management
- A.9 Access control
- A.10 Cryptography
- A.11 Physical and environmental security
- A.12 Operations security
- A.13 Communications security
- A.14 System acquisition, development and maintenance
- A.15 Supplier relationships
- A.16 Information security incident management
- A.17 Information security aspects of business continuity management
- A.18 Compliance
ISO 27001 benefits
Protect your data, wherever it lives
An ISO 27001-compliant ISMS helps protect all forms of information, whether digital, paper-based or in the Cloud.
Increase your attack resilience
Implementing and maintaining an ISMS will significantly increase your organisation's resilience to cyber attacks.
Reduce information security costs
Thanks to the risk assessment and analysis approach of an ISMS, organisations can reduce costs spent on indiscriminately adding layers of defensive technology that might not work.
Respond to evolving security threats
Constantly adapting to changes both in the environment and inside the organisation, an ISMS reduces the threat of continually evolving risks.
Improve company culture
The Standard’s holistic approach enables employees to readily understand risks and embrace security controls as part of their everyday working practices.
Meet contractual obligations
Certification demonstrates your organisation’s commitment to information security and provides a valuable credential when tendering for new business.
