The digital forensic discipline is wholly reliant upon software applications and tools designed and marketed for the acquisition, display and interpretation of digital data. The results of any subsequent investigation using such tools must be reliable and repeatable whilst supporting the establishment of fact, allowing criminal justice proceedings the ability to digest any findings during the process of determining guilt or innocence. Errors present at any stage of an examination can undermine an entire investigation, compromising any potentially evidential results. Despite a clear dependence on digital forensic tools, arguably, the field currently lacks sufficient testing standards and procedures to effectively validate their usage during an investigation. Digital forensics is a discipline which provides decision-makers with a reliable understanding of digital traces on any device under investigation, however, it cannot say with 100% certainty that the tools used to undertake this process produce factually accurate results in all cases. This is an increasing concern given the push for digital forensic organisations to now acquire ISO 17025 accreditation. This article examines the current state of digital forensic tool-testing in 2018 along with the difficulties of sufficiently testing applications for use in this discipline. The results of a practitioner survey are offered, providing an insight into industry consensus surrounding tool-testing and reliability.

数字取证学科完全依赖为获取，显示和解释数字数据而设计和销售的软件应用程序和工具。使用此类工具进行的任何后续调查的结果必须可靠且可重复，同时支持事实的确立，从而使刑事司法程序能够在确定有罪或无罪的过程中消化任何发现。在检查的任何阶段出现的错误都可能破坏整个调查，损害任何可能的证据结果。尽管显然依赖数字取证工具，但是可以说，该领域目前缺乏足够的测试标准和程序来有效地验证调查过程中的使用。数字取证是一门为决策者提供对被调查设备上的数字迹线的可靠了解的学科，但是，它不能100％地确定用于进行此过程的工具在所有情况下都能产生事实准确的结果。鉴于推动数字取证组织现在获得ISO 17025认证的担忧日益增加。本文研究了2018年数字取证工具测试的现状，以及充分测试适用于该学科的应用程序的困难。提供了从业人员调查的结果，可深入了解围绕工具测试和可靠性的行业共识。它不能100％地确定在所有情况下用于执行此过程的工具都会产生事实准确的结果。鉴于推动数字取证组织现在获得ISO 17025认证的担忧日益增加。本文研究了2018年数字取证工具测试的现状，以及充分测试适用于该学科的应用程序的困难。提供了从业人员调查的结果，可深入了解围绕工具测试和可靠性的行业共识。它不能100％地确定在所有情况下用于执行此过程的工具都会产生事实准确的结果。鉴于推动数字取证组织现在获得ISO 17025认证的担忧日益增加。本文研究了2018年数字取证工具测试的现状，以及充分测试适用于该学科的应用程序的困难。提供了从业人员调查的结果，可深入了解围绕工具测试和可靠性的行业共识。本文研究了2018年数字取证工具测试的现状，以及充分测试适用于该学科的应用程序的困难。提供了从业人员调查的结果，可深入了解围绕工具测试和可靠性的行业共识。本文研究了2018年数字取证工具测试的现状，以及充分测试适用于该学科的应用程序的困难。提供了从业人员调查的结果，可深入了解围绕工具测试和可靠性的行业共识。
