Websites : new material on the book website – now up to chapter 6 with the exercises! (bet it’ll take me longer to do the model answers though) – see http://www.digital-forensics.org.uk/
Fitness for pupose tests In the last week or so I’ve been talking to a lot of people about the “fitness for purpose (ffp)” requirement that the regulator’s working group have recommended for the digital evidence standard. We’ve been kicking around ideas about how this can be demonstrated. At one level, the vendors could go for ISO17025 or CESG CTM (CTM) certification themselves – but this only really tests the product “out of the box” as they ship it, with no real accounting for how it is used in the field. This is a particular problem, I think, for anything which includes scripting capabilities as each script will still need to pass the ffp test. It gets worse when we start to think about all the really good open source, non-forensic software and tools produced by small companies without the budget or resources for performing their own ffp testing.

I am more convinced than ever that we need to introduce a national ffp testing service which can deal with the complexities of non-standard hardware and software combinations, in-house developed tools and rapid deployment of vital patches.

It’ll be a heck of challenge to get it right, but you know something ? – I really want to try to make it work!
