Computer forensics can be broken down into four phases: collection, preservation, filtering, and presentation of computer system artifacts that are of potential evidentiary value. The case Gates Rubber Co. v. , Ltd. highlighted nonstandard forensics procedures, resulting in the destruction and loss of potentially valuable artifacts to the case.

In this step, the first responder establishes if the crime is still occurring and notes the physical characteristics of the surrounding area. For computer forensics investigators, this responsibility can be extended to data systems that are live in a network environment. The step can include systems that may have been interacting with the primary computer of interest, whether local or remote. In these cases, the computer may be the target of an ongoing attack, such as a denial of service (DoS).
