To filter out known good or system files, which EnCase process do you apply?

The process to filter out known good or system files using EnCase involves applying file hash analysis. This method utilizes hash values that are pre-calculated and stored in databases to identify files that are commonly recognized as benign or part of the operating system (e.g., system files, application files). By comparing the hash values of the files found in the evidence against these known hash databases, investigators can effectively filter out those files that do not need further examination, allowing them to focus on potentially malicious files.

File hash analysis is particularly advantageous as it provides a reliable way to identify files without the need to examine their content or structure directly. In digital forensics, this is crucial for maintaining efficiency in analysis while ensuring that critical data is not overlooked. By using hash analysis, examiners can quickly flag known good files, streamlining the investigation process.

In contrast, other options like file signature analysis are used to identify file types by examining file headers but do not inherently aid in filtering out known good files. The Recover Folders feature assists in reconstructing the directory structure of a file system but does not focus on known good file identification. A file content search involves analyzing the actual content within files, which may not effectively distinguish known good files from other data without prior hash
