ISO 27001 Certification: What is it and what is its purpose?

Information and digital security has become a critical concern in today’s digital age. 

Organizations continually face risks related to the confidentiality, integrity, and availability of the data they handle.

In this context, ISO 27001 certification emerges as a fundamental approach to establish and maintain an effective Information Security Management System (ISMS). 

In this article, we will explore the fundamental logic behind ISO 27001 standards and certification, and how it works to safeguard information assets.

What Is ISO 27001? 

ISO 27001 is an internationally recognized standard and security framework that provides a structure for establishing, implementing, operating, monitoring, reviewing, maintaining, and improving an ISMS within the context of an organization’s overall risks.

What Is the Purpose of ISO 27001? 

The ISO 27001 standard serves to establish a robust and structured framework for information security management within an organization

Its primary purpose is to ensure the protection of information assets, including sensitive and critical data, against threats and risks that could compromise their confidentiality, integrity, and availability.

By implementing ISO 27001 certification, organizations can effectively identify, assess, and manage security risks, establishing appropriate controls and measures to prevent incidents and ensure continuous information security management. 

Moreover, this standard not only contributes to risk mitigation but also enhances customer trust, improves legal compliance, and promotes continuous improvement in information security in today’s business environment.

Principles of ISO 27001 Standard

The ISO 27001 standard is built upon a set of key principles that guide the effective implementation of an Information Security Management System (ISMS)

These principles help organizations establish and maintain a robust approach to protecting sensitive and critical information. 

Here are the main principles of the ISO 27001 standard:

  • Risk-Based Approach: The standard focuses on the proactive identification and management of information security risks, involving the assessment of potential risks and taking measures to mitigate them.
  • Leadership and Commitment: Top management must lead and demonstrate commitment to information security by allocating resources, defining policies and objectives, and participating in key decision-making.
  • Organizational Context: The standard recognizes the importance of understanding the organization’s context, including its environment, needs, and objectives.
  • Process-Based Approach: ISO 27001 promotes the implementation of security controls as part of coherent and well-defined organizational processes.
  • Continuous Improvement: The standard advocates for continuous improvement of the ISMS through results review, adoption of corrective and preventive actions, and adaptation to changes in the environment.
  • Involvement of Personnel: Information security is everyone’s responsibility in the organization. ISO 27001 emphasizes the importance of involving all personnel in information protection.
  • Documentation and Evidence: The standard underscores the need to document policies, procedures, and evidence of actions taken to ensure information security.
  • Effective Communication: Clear and effective communication about information security matters is crucial to keeping all stakeholders informed and aligned.
  • Holistic Management: ISO 27001 covers both technical and organizational aspects of information security, ensuring a comprehensive and holistic approach.

These core principles form the foundation upon which the ISMS is built according to the ISO 27001 standard.

By following these principles, organizations can establish a robust and effective information security management system that protects their information assets and instills confidence in all their operations.

The ISO 27001 structure is based on the Plan-Do-Check-Act (PDCA) cycle, which is an iterative approach to continuous improvement. 

Each section plays a specific role in the development and maintenance of the ISMS, ensuring that information security remains an integral and ongoing part of organizational operations.


In this stage, the organization identifies information security risks and opportunities. Objectives are set, and a strategy is defined to address identified risks.


In this phase, the organization implements the security measures defined in the planning stage. This involves the implementation of controls and procedures to mitigate risks.


Here, a comprehensive assessment is conducted to determine the effectiveness of the implemented controls. Internal audits and performance reviews are carried out.


Corrective and preventive actions are taken based on the results of audits and reviews. This ensures that the information security system remains up-to-date and effective in a constantly changing environment.

Benefits of ISO 27001 Certification 

Implementing the ISO 27001 standard in your organization provides several key benefits. 

We list them below:

  • Risk Management: ISO 27001 certification offers a structured approach to identifying, evaluating, and addressing information security risks. This enables organizations to anticipate and mitigate potential threats.
  • Customer Trust: Compliance with internationally recognized security standards demonstrates an organization’s commitment to safeguarding confidential customer information.
  • Legal Compliance: ISO 27001 certification helps organizations comply with information security regulations and privacy laws applicable to their industry and location.
  • Continuous Improvement: The PDCA cycle of ISO 27001 encourages continuous improvement in information security processes within the organization.

How to Implement ISO 27001 in Your Organization 

Implementing the ISO 27001 standard in your organization is a process that requires planning, commitment, and focus. Here’s a step-by-step guide to help you in this process:

1. Understand the Standard 

Begin by familiarizing yourself with the requirements and principles of the ISO 27001 standard. Read the standard in its entirety and grasp its structure, goals, and focus on information security management.

2. Leadership Commitment

Support from top management is essential for successful implementation. The leadership must understand the importance of information security and commit to allocating resources and actively participating in the process.

3. Establish an Implementation Team

Form a multidisciplinary team that includes representatives from different areas of the organization. This team will be responsible for leading the implementation and coordinating necessary activities.

4. Initial Assessment: 

Conduct an initial assessment of the current state of information security in your organization. Identify existing information assets, risks, threats, and vulnerabilities.

5. Define Scope 

Establish the scope of your Information Security Management System (ISMS). Define which assets will be covered, which areas of the organization will be included, and which processes will be affected.

6. Risk Identification

Identify and assess information security risks associated with the assets and processes defined in the scope. Use methodologies like risk analysis to determine the likelihood and impact of each risk.

7. Control Development

Develop security controls and measures to mitigate identified risks. Controls can include policies, procedures, technologies, and specific practices.

8. Control Implementation

Implement the defined controls in relevant areas of the organization. Ensure that employees are informed and trained on the new procedures and practices.

9. Documentation Creation

Create the documentation required by the standard, such as the Information Security Policy, ISMS Manual, and standard operating procedures. These documents will establish the foundation for the management system.

10. Conduct Internal Audits

Perform regular internal audits to assess the ISMS’s compliance with ISO 27001 requirements. This will help identify areas for improvement and ensure the system functions effectively.

11. Management Review

Conduct periodic reviews with top management to evaluate the ISMS’s performance and make strategic decisions. These reviews ensure the system remains relevant and effective.
