ISO 27001 is an international standard focused on Information Security Management Systems (ISMS) and their requirements. It is part of a set of standards, such as ISO/SEC 27001:2013, developed to help organisations implement and handle information security.
ISO 27001 standard provides a framework of procedures and policies that include all physical, legal, and technical controls concerned with a company’s information risk management procedures. To be ISO 27001 compliant means that your company has passed an external audit and fulfilled all compliance requirements.
Is ISO 27001 Compliance Mandatory?
Compliance with ISO 27001 standard is not compulsory. However, with the increasing rate of cyber risks and hackers who persistently target your data and information privacy mandates attract harsh penalties, observing ISO standards is important for various reasons. It will help you comply with legal requirements, reduce risks, reduce costs, and improve data integrity.
Achieving ISO certification is a good way to prove to your customers and business associates that you safeguard their data, which can help attract and retain customers. Since ISO 27001 is an internationally recognised standard, it can increase your business opportunities on a global scale.
How ISO 27001 Works
ISO 27001 safeguards the confidentiality, integrity, and accessibility of the data or information in an organisation. This is often achieved through risk assessment, which involves identifying potential problems that could occur to an information system and suggesting the most appropriate risk management or mitigation strategies.
In short, ISO 27001 focuses on risk management, pinpointing potential risks and alleviating these risks through the deployment of information security controls.
Requirements and Security Controls for ISO 27001
The ISO 27001 standard is classified into two main parts. The first part outlines definitions and requirements:

- Support: States that a facility should assign sufficient resources, create awareness, and develop the necessary documentation.
- Performance Evaluation: Needs a company to consistently track, measure, and evaluate its ISMS controls and processes.
- Operation: Provides a framework for identifying and treating information risks, handling changes, and achieving appropriate documentation.
- Planning: Specifies the procedure to establish and plan to manage information risks and define the objective of ISMS initiatives.
