Dear community members,
Hopefuly you can answer to this question as experts in Digital Forensics field. I am thinkig under criterias based on which the reliability of forensics tools can be tested including methodologies, standards such as NIST, NIJ etc. Perhaps there could be something else that can take a place.
What is you view regarding this? What criterias can be included?
Basically I want to create a table with criterias and comparisons. Each opinion would be valuable.
"Forensic tools" is too broad a category. What applies to one tool or even one category of tools will likely not apply to another. For example the tests you would use to validate a MacOS tool would likely not be the criteria you would use for a tool to examine mobile devices. Even if you look at a general category such as imaging tools there will be enough differences to make it difficult to create a table of testing steps.
PreferredUser is right, you need to be very specific when comparing tools. First, you need to figure out what you're trying to accomplish. Are you trying to compare features, or are you trying to validate the tool? Comparing features doesn't require too many standard methodologies and it's easy to make a comparison table for that.
Validation is something else completely. This does require a thorough test and the "table" you create would mostly be showing the results of the validation. As long as you use a scientific method for testing and do the exact same steps for each individual tool, you should be able to get the results you need to report on.
Just my opinion, but a table is a poor way to show full validation of a tool for any scientific field. Research and white papers are the best way to fully explain what you are doing, why you are doing it, how you are doing it, and the results.
