Evidence and Incidents

Evidence and incidence IT security standards are published by ISO and IEC. They include the ISO/IEC 27035 series, which covers Principles of incident management, Guidelines to plan and prepare for incident response, and guidelines for identification, collection, acquisition and preservation of digital evidence.

ISO/IEC 27035-1:2023

Information technology - Information security incident management - Part 1: Principles and process

This document is the foundation of the ISO/IEC 27035 series . It presents basic concepts, principles and process with key activities of information security incident management, which provide a structured approach to preparing for, detecting, reporting, assessing, and responding to incidents, and applying lessons learned. The guidance on the information security incident management process and its key activities given in this document are generic and intended to be applicable to all organizations, regardless of type, size or nature. Organizations can adjust the guidance according to their type, size and nature of business in relation to the information security risk situation. This document is also applicable to external organizations providing information security incident management services.

ISO/IEC 27035-2:2023

Information technology - Information security incident management - Part 2: Guidelines to plan and prepare for incident response

This document provides guidelines to plan and prepare for incident response and to learn lessons from incident response. The guidelines are based on the “plan and prepare” and “learn lessons” phases of the information security incident management phases model presented in ISO/IEC 27035 - 1 : 2023 , 5.2 and 5.6 . The major points within the “plan and prepare” phase include: — information security incident management policy and commitment of top management; — information security policies, including those relating to risk management, updated at both organizational level and system, service and network levels; — information security incident management plan; — Incident Management Team (IMT) establishment; — establishing relationships and connections with internal and external organizations; — technical and other support (including organizational and operational support); — information security incident management awareness briefings and training. The “learn lessons” phase includes: — identifying areas for improvement; — identifying and making necessary improvements; — Incident Response Team (IRT) evaluation. The guidance given in this document is generic and intended to be applicable to all organizations, regardless of type, size or nature. Organizations can adjust the guidance given in this document according to their type, size and nature of business in relation to the information security risk situation. This document is also applicable to external organizations providing information security incident management services.

ISO/IEC 27037:2012

Information technology - Security techniques - Guidelines for identification, collection, acquisition and preservation of digital evidence

ISO/IEC 27037:2012 provides guidelines for specific activities in the handling of digital evidence, which are identification, collection, acquisition and preservation of potential digital evidence that can be of evidential value. It provides guidance to individuals with respect to common situations encountered throughout the digital evidence handling process and assists organizations in their disciplinary procedures and in facilitating the exchange of potential digital evidence between jurisdictions. ISO/IEC 27037:2012 gives guidance for the following devices and circumstances: Digital storage media used in standard computers like hard drives, floppy disks, optical and magneto optical disks, data devices with similar functions, Mobile phones, Personal Digital Assistants (PDAs), Personal Electronic Devices (PEDs), memory cards, Mobile navigation systems, Digital still and video cameras (including CCTV), Standard computer with network connections, Networks based on TCP/IP and other digital protocols, and Devices with similar functions as above. The above list of devices is an indicative list and not exhaustive.
