NTFS Artifact Analysis is the examination of residual data and metadata left behind on a computer's file system, specifically the Windows New Technology File System (NTFS). This process involves recovering deleted files, examining file timestamps, identifying access control lists, and reconstructing file system activity to understand past events. It is crucial for digital forensics investigations, incident response, and security audits, providing evidence of user actions or system changes. For instance, analyzing the Master File Table (MFT) can reveal when a file was created, modified, or accessed, even if the file itself has been deleted. This differs from simple file recovery by focusing on the underlying file system structures and their historical implications. NTFS Artifact Analysis is a key skill tested in domains like digital forensics and incident response, relevant to certifications such as CompTIA CySA+.
