Evidence assessment is a critical step in the investigation phase of the computer forensics process. This step involves evaluating the evidence collected to determine its relevance and significance to the case at hand. It includes analyzing the secured data to identify what information can be used as evidence, its integrity, and how it can be related to the security incident. This phase is pivotal as it helps in building a coherent understanding of the incident and in establishing facts that can be presented in management reports or legal proceedings.
