ISO/IEC 27041:2015提供了有关机制的指南，以确保信息安全事件调查中使用的方法和过程“适合目的”。它封装了定义需求、描述方法以及提供证据证明方法的实现可以满足需求的最佳实践。它包括考虑如何使用供应商和第三方测试来协助该保证过程。 本文件旨在 ? 提供与信息安全（IS）事件调查相关的功能性和非功能性需求捕获和分析指南， ? 就验证的使用提供指导，以确保调查过程的适用性， ? 提供评估所需验证水平和验证活动所需证据的指南， ? 就如何将外部测试和文件纳入验证过程提供指导。

ISO/IEC 27041:2015 provides guidance on mechanisms for ensuring that methods and processes used in the investigation of information security incidents are "fit for purpose". It encapsulates best practice on defining requirements, describing methods, and providing evidence that implementations of methods can be shown to satisfy requirements. It includes consideration of how vendor and third-party testing can be used to assist this assurance process. This document aims to ? provide guidance on the capture and analysis of functional and non-functional requirements relating to an Information Security (IS) incident investigation, ? give guidance on the use of validation as a means of assuring suitability of processes involved in the investigation, ? provide guidance on assessing the levels of validation required and the evidence required from a validation exercise, ? give guidance on how external testing and documentation can be incorporated in the validation process.
