What is ISO 27035?




ISO 27035 is a set of standards that provide guidance on information security incident management for organizations of different sizes and types. The standards describe a 5-phase process for incident response: prepare, detect and report, assess and decide, respond, and learn lessons. ISO 27035-1 is the foundation of the series and presents basic concepts, principles, and processes for information security incident management. The standards are intended to be applicable to all organizations, regardless of type, size, or nature.


The history and development of ISO 27035




The first edition of ISO 27035 was published in 2011 as ISO/IEC 27035:2011. It was a single document that covered the entire incident management process in one standard. However, in 2016, the standard was revised and split into two parts: ISO/IEC 27035-1:2016 and ISO/IEC 27035-2:2016. The first part focused on the principles of incident management, while the second part focused on the guidelines for planning and preparing for incident management.


In 2020, the second part was updated and renamed as ISO/IEC 27035-3:2020. It expanded the scope of the guidelines to cover all phases of incident management, not just planning and preparing. In 2023, the first part was also updated and renamed as ISO/IEC 27035-1:2023. It incorporated some changes and clarifications to the principles and process of incident management.


The current version of ISO 27035 consists of two parts: ISO/IEC 27035-1:2023 and ISO/IEC 27035-3:2020. The former provides the foundation and framework for incident management, while the latter provides the detailed guidance and best practices for implementing incident management.


The structure and scope of ISO 27035




The structure of ISO 27035 is based on a five-phase process for information security incident management. The five phases are:


  • Prepare: This phase involves establishing the necessary policies, procedures, roles, responsibilities, resources, tools, and training for effective incident management.



  • Detect and report: This phase involves identifying and verifying information security incidents, collecting and preserving evidence, and notifying relevant stakeholders.



  • Assess and decide: This phase involves analyzing and evaluating information security incidents, determining their severity and impact, and deciding on the appropriate response strategy.



  • Respond: This phase involves containing and eradicating information security incidents, recovering and restoring normal operations, and communicating and coordinating with internal and external parties.



  • Learn lessons: This phase involves reviewing and documenting information security incidents, identifying and implementing improvements, and sharing and disseminating lessons learned.



The scope of ISO 27035 covers all types of information security incidents that affect any aspect of information or information systems within an organization. It also covers incidents that involve external parties, such as customers, suppliers, partners, regulators, or attackers. The standard applies to both technical and non-technical incidents, such as malware infections, denial-of-service attacks, phishing scams, data breaches, unauthorized access, theft or loss of devices or media, human errors or mistakes, fraud or sabotage.


The benefits and challenges of ISO 27035
