What is ISO 27001?

ISO 27001 is an international standard that stipulates the requirements for establishing, implementing, maintaining, and continuously improving an organization’s Information Security Management System (ISMS).

It is published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

ISO 27001 provides a framework for systematically managing and protecting sensitive information, including data, processes, systems, and infrastructure.

The primary objective of ISO 27001 is to help organizations establish a comprehensive and risk-based approach to information security.

It provides a systematic methodology for identifying and assessing information security risks, implementing appropriate controls to mitigate those risks, and continually monitoring and improving the effectiveness of the ISMS.

ISO 27001 takes a comprehensive approach to information security, encompassing various aspects such as organizational policies, procedures, people, technology, and physical security.

It sets out requirements that organizations must meet to achieve certification, ensuring they have implemented a robust and well-documented ISMS that aligns with international best practices.

The key benefits of implementing ISO 27001 include the following:

• Risk management: ISO 27001 helps organizations identify and prioritize information security risks, enabling them to allocate resources effectively to mitigate those risks and protect their critical assets.
• Compliance:  ISO 27001 assists organizations in meeting legal, regulatory, and statutory requirements related to information security, ensuring they operate within the boundaries of applicable laws and regulations.
• Stakeholder confidence: Achieving ISO 27001 certification enhances the trust and confidence of stakeholders, including customers, partners, and shareholders, as it demonstrates the organization’s commitment to protecting sensitive information.
• Continual improvement: ISO 27001 promotes a culture of continual improvement by establishing a framework for regularly monitoring and evaluating the effectiveness of the ISMS. This allows organizations to adapt to evolving threats and vulnerabilities and enhance their overall security posture over time.

What is ISO 27002?

ISO 27002, also known as ISO/IEC 27002:2013, is an international standard for establishing, carrying out, upholding, and enhancing an Information Security Management System (ISMS).

It provides an exhaustive set of controls and measures organizations can implement to ensure their information assets’ confidentiality, integrity, and availability.

ISO 27002 serves as a companion document to ISO 27001, which outlines the requirements for establishing an ISMS.

While ISO 27001 focuses on the overall management system and risk assessment, ISO 27002 delves into the specific controls organizations can implement to address information security risks identified during risk assessment.

Implementing ISO 27002 from Perimeter81 brings several benefits to organizations regarding information security management. Some key benefits include:

• Comprehensive guidance: ISO 27002 provides complete guidelines and best practices for implementing information security controls. By following these guidelines, organizations can ensure that they have addressed critical security areas and have a well-rounded approach to protecting their information assets.
• Risk-based approach: ISO 27002 aligns with the risk management principles of ISO 27001. It helps organizations assess and prioritize information security risks and effectively select appropriate controls to mitigate them. This risk-based approach ensures that resources are allocated efficiently and that security efforts focus on the most significant threats.
• Enhanced security posture: By implementing the controls recommended by ISO 27002, organizations can improve their overall security posture. The standard covers various domains, including access control, cryptography, physical security, incident management, and more, providing a comprehensive framework for addressing security vulnerabilities and protecting sensitive information.
• Compliance with regulations and standards: ISO 27002 assists organizations in meeting regulatory and legal requirements related to information security. It helps ensure compliance with industry-specific regulations and standards, such as the General Data Protection Regulation (GDPR), Payment Card Industry Data Security Standard (PCI DSS), and others.
• Stakeholder confidence and trust: Adhering to ISO 27002 demonstrates an organization’s commitment to information security and can enhance stakeholder confidence. Customers, partners, and other stakeholders are likelier to trust an organization that follows recognized international standards and implements robust security controls to protect their data and sensitive information.
• Alignment with industry best practices: ISO 27002 is based on widely accepted best practices in information security management. By aligning their practices with these standards, organizations can demonstrate that they follow industry-leading approaches to protecting information and mitigating security risks.
• Continual improvement: ISO 27002 emphasizes the importance of continual improvement in information security management. By regularly reviewing and updating their security controls based on evolving threats and vulnerabilities, organizations can adapt to changing circumstances and maintain a proactive stance against emerging risks.
• Competitive advantage: ISO 27002 certification or adherence to its guidelines can provide a competitive advantage for organizations. It showcases their commitment to information security, which can be a differentiating factor when seeking new clients, business partners, or contracts.
