ISO/IEC 27035 is an international standard series for information security incident management that provides structured processes for the detection, reporting, assessment, response, and follow-up of security incidents. It helps organizations increase their resilience against cyber threats. The standard consists of several parts, including fundamentals, planning, ICT operations, and coordinated incident response.
Key Content and Structure (ISO/IEC 27035 series):
ISO/IEC 27035-1:2023 – Principles and Process: Provides a basic framework for managing information security incidents.
ISO/IEC 27035-2:2023 – Guidance on Planning and Preparation: Includes detailed guidance on preparing for and responding to incidents to minimize their impact.
ISO/IEC 27035-3:2020 – Guidance on ICT Incident Response Measures: Focuses on the technical operations involved in responding to incidents.
ISO/IEC 27035-4:2024 – Coordinated Incident Management: Addresses the collaboration of multiple organizations.
Core Incident Management Processes:
Preparation: Establishing plans, policies, and teams (CSIRT/SOC).
Detection & Reporting: Identifying and documenting security events.
Assessment & Decision: Analyzing whether an event constitutes a security incident.
Response: Containment, Eradication, and Recovery.
Lessons Learned: Post-incident analysis to minimize future risks.
This standard is suitable for all organizations, regardless of size or type. It is closely related to ISO/IEC 27001, especially when a Computer Security Incident Response Team (CSIRT) is implemented as part of an Information Security Management System (ISMS).
