You’ve probably heard or read somewhere that there’s a globally accepted standard for managing information security known as ISO/IEC 27001. 

In order to manage information security, it offers a planned and methodical strategy that takes into account people, processes, and technology. The Information Security Management System (ISMS) is a cornerstone of ISO 27001, with the goal of selecting suitable and proportionate security policies to safeguard information assets and instill trust in those involved.

Understanding ISO 27001 Controls

ISO 27001 controls are outlined in Annex A of the standard, providing a comprehensive framework for organizations to secure their information assets. As of the latest version, ISO 27001:2013, there are a total of 114 controls, divided into 14 categories, also known as control sets. 

These controls are not mandatory for all organizations but are to be considered based on the organization’s risk assessment results. 

The goal is to identify which controls are necessary to mitigate identified risks to an acceptable level. It is this flexibility and adaptability that make ISO 27001 a versatile and powerful tool for information security management. A great idea is to take a look at this link if you’re eager to understand more about this amazing tool. 

So, let’s find out more about these categories, shall we? 

Information Security Policies

These controls emphasize the need for a set of policies specifically focused on information security, defined by management, and made available to all employees and relevant external parties. These policies serve as the foundation for the organization’s information security practices, outlining expectations, responsibilities, and how information security is managed and implemented.

Organization of Information Security

This category is concerned with the establishment of an internal organization framework to ensure consistent implementation and management of information security across the enterprise. It includes controls for allocating responsibilities for information security management and securing agreements with external parties regarding the handling of assets and information security.

This includes controls for the entire lifecycle of an employee within the organization, from pre-employment screening to post-employment responsibilities, aiming to prevent and mitigate human-related security breaches.

Asset Management

This category deals with identifying information assets within the organization and assigning a suitable level of protection to them. It includes controls for asset inventory, ownership responsibilities, and information classification. Proper asset management ensures that all assets are accounted for and adequately protected according to their value and sensitivity.

Access Control

Access control is crucial for limiting access to information and information processing facilities. Controls in this category ensure that access is granted based on business necessity and that users are aware of their access rights. It covers user access management, user responsibilities, and system and application access control, aiming to prevent unauthorized access to sensitive information.


Controls in this category guide the use of cryptographic measures to secure both data at rest and data in transit, addressing key management and the application of cryptographic controls in line with the organization’s information security policy.

Physical and Environmental Security

These controls are designed to protect the organization’s physical assets from a wide range of threats. It encompasses securing the physical perimeter, protecting against damage from environmental hazards, securing equipment and cabling, and managing secure disposal or reuse of equipment. Physical and environmental security is fundamental to protecting information assets from unauthorized physical access, damage, or interference.

Operations Security

This category focuses on the procedures and responsibilities necessary to ensure secure operations of information processing facilities. It covers aspects like documented operating procedures, malware protection, backup, logging and monitoring, and the management of technical vulnerabilities, aiming to ensure the integrity and availability of information processing and storage.

Communications Security

Managing the security of information in networks and protecting communications. This category includes controls for network security management and information transfer, ensuring that information in transit is appropriately protected against unauthorized access, modification, or interception.

System Acquisition, Development, and Maintenance

Controls here ensure that information security is an integral part of the lifecycle of information systems, from initial requirements gathering to retirement.

Enhanced Information Security

The first function of ISO 27001 is to protect and secure an organization’s information assets. By establishing and implementing a rigorous ISMS, companies can ensure the confidentiality, integrity, and availability of their data.

Compliance with Regulatory Requirements

Many industries are subject to strict regulatory requirements regarding data protection and privacy. Adopting ISO 27001 can help organizations comply with these legal and contractual obligations, including regulations such as the General Data Protection Regulation (GDPR) in the European Union. This not only helps avoid potential fines and legal penalties but also demonstrates a commitment to information security.

Competitive Advantage

 In a marketplace where consumers and partners are increasingly concerned about data security, ISO 27001 certification can serve as a significant differentiator. It signals to customers, suppliers, and stakeholders that the organization is committed to managing information securely. This can enhance trust and confidence in the brand, potentially leading to increased business opportunities.

Systematic Risk Management

In order to comply with the requirements of ISO 27001, businesses are required to conduct a comprehensive assessment of the risks associated with information security. This assessment must take into account the impact that threats and vulnerabilities have on the availability, integrity, and confidentiality of information. 

This approach ensures that organizations can identify and prioritize risks, applying appropriate controls to mitigate them effectively.

Improved Organization and Clarity

Implementing ISO 27001 helps organizations streamline their processes related to information security. It encourages a clear definition of roles and responsibilities concerning information security, promoting greater awareness, and understanding among employees. This organizational clarity can lead to more efficient operations and a stronger security culture within the company.

Continual Improvement

ISO 27001 is based on a principle of continual improvement, requiring organizations to regularly review and refine their ISMS. This not only helps maintain a high level of security over time but also ensures that the ISMS adapts to changes in the external and internal environment, including new threats, technologies, and business objectives.

International Recognition

As an internationally recognized standard, ISO 27001 certification can help organizations access global markets more easily. It demonstrates that the company adheres to a globally accepted benchmark for information security, which can be particularly important when dealing with international clients or entering new markets.
