Review Of Enterprise 6.5.1 From AccessData - Rich2005 shared their thoughts on ISO 17025 and doesn’t think that it’s a good fit for digital forensics. The interesting point made was that obtaining the certification is restrictive for smaller shops. I don’t know a lot about the standard, or the process of getting the certification, but I do think that there should be a barrier to entry to becoming an examiner for cases. The example provided showed a skilled defence examiner, however, that’s not always the case; in some cases, someone who has worked in computers can be accepted as an expert when they don’t know a lot about the actual DF field.
Opinion: Is ISO17025 The Right Standard For Digital Forensics? - They interviewed Angus Marshall about his work on standardisation and tool testing based on his recently published paper: “Requirements in digital forensics method definition: observations from a UK study”
