Overview of Relevant Standards: ISO/IEC 27035 and Alignment with ISO/IEC 27001

Lesson 4/35 | Study Time: 15 Min

Course: ISO 27035 Information Security Incident Manager Course

In the realm of information security, adherence to internationally recognized standards is essential for establishing effective processes and achieving organizational resilience.

ISO/IEC 27035 and ISO/IEC 27001 are two pivotal standards that guide organizations in managing information security risks and incident response effectively.

Understanding these standards and their alignment supports a cohesive approach to securing information assets and maintaining compliance with regulatory requirements.

ISO/IEC 27035: Information Security Incident Management

ISO/IEC 27035 is a comprehensive international standard specifically focused on information security incident management. It provides organizations with a structured framework to detect, report, assess, and respond to information security incidents.

Updated in 2023, the standard defines best practices and a lifecycle approach for handling incidents to mitigate their impact and prevent recurrence.

ISO/IEC 27001: Information Security Management System (ISMS)

ISO/IEC 27001 is the overarching standard for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).

It sets out requirements for a systematic approach to managing sensitive company information so that it remains secure.

The key aspects of ISO/IEC 27001 include:

1. Risk-Based Approach: Identifying and treating information security risks through appropriate controls.

2. Leadership and Commitment: Ensuring top management’s involvement and commitment to information security policies.

3. Performance Evaluation: Monitoring and measuring the effectiveness of the ISMS.

4. Annex A Controls: Provides a comprehensive list of security controls addressing various security domains and threats.

Alignment Between ISO/IEC 27035 and ISO/IEC 27001

The alignment of ISO/IEC 27035 with ISO/IEC 27001 makes incident management an integral part of an organization’s ISMS. This combined approach enhances security by linking incident handling directly to risk management and organizational controls.

ISO/IEC 27001 Clause	Alignment with ISO/IEC 27035	Key Contribution
Clause 6 – Planning	ISO/IEC 27035 supports the planning and preparation for information security incidents as part of the organization’s risk treatment strategies.	Integrates incident response planning into overall risk management, ensuring preparedness.
Clause 8 – Operation	Guides the implementation and operation of incident detection, reporting, assessment, and response processes.	Ensures the organization can effectively manage and respond to incidents in real time.
Clause 9 – Performance Evaluation	Encourages continuous monitoring, reporting, and analysis of incidents to assess control effectiveness.	Provides measurable insights and feedback to evaluate ISMS performance.
Clause 10 – Improvement	Promotes learning from incidents to drive continual improvement and policy refinement.	Strengthens organizational resilience through corrective actions and updated procedures.
