Why is it difficult to collect relevant digital evidence?
Digital evidence is volatile and fragile and the improper handling of this evidence can alter it. Because of its volatility and fragility, protocols need to be followed to ensure that data is not modified during its handling (i.e., during its access, collection, packaging, transfer, and storage).
