Forensic Specialist
The computer forensic specialist takes several careful steps to identify and retrieve evidence that exists on the subject computer system.
- Protects the subject computer system during the forensic examination from any alteration, damage, data corruption, or virus introduction.
- Discovers all files on the subject system. This includes existing normal files, deleted yet remaining files, hidden files, password protected files, and encrypted files.
- Recovers all of discovered deleted files. Reveals the contents of ‘hidden files’ as well as temporary or ‘swap files’ used by both the application programs and the operating system.
- Analyzes all relevant data found in special (and typically inaccessible) areas of a disk. This includes but is not limited to what is called 'unallocated' space on a disk (currently used, but the repository of previous data that is relevant evidence), as well as 'slack' space in a file (the remnant area at the end of a file, in the last assigned disk cluster, that is unused by current file data, but once again may be a possible site for previously created and relevant evidence).
