11. Frage
A government organization decided to establish a computer forensics lab to perform transparent investigation processes on highly sensitive cases. The organization also decided to establish strong physical security around the premises of the forensics lab.
Which of the following security measures helps the organization in providing strong physical security to the forensics lab?
Antwort: D
Begründung:
Forensics labs handling highly sensitive investigations must protect evidence confidentiality and prevent unauthorized disclosure. Strong physical security includes not only access control and surveillance, but also protections againstelectromagnetic (EM) emanationrisks. Computers and displays can unintentionally emit electromagnetic signals that, under certain conditions, may be intercepted and reconstructed to reveal sensitive information (for example, case notes, recovered evidence content, or credentials). Digital forensics lab design guidance recognizes this as a real threat in high-sensitivity environments and recommendsEM shielding / TEMPEST-style controlswhere appropriate. Shielding workstations reduces the chance of data leakage through side-channel interception and helps ensure that confidential investigative activities cannot be monitored from outside controlled areas.
The other options directly weaken physical security and safety. Fire extinguishers are required for facility safety and risk management, so "never place" them is unsafe and contrary to secure lab standards. Not maintaining an entrance log register undermines chain-of-custody support and accountability by removing a basic access auditing mechanism. "Never keep the lab under surveillance" removes a core deterrent and detection control for unauthorized entry, evidence tampering, and theft. Therefore, shielding workstations from transmitting electromagnetic signals is the only option thatstrengthensphysical security for a sensitive forensics lab.
12. Frage
Jack, a forensic investigator, was appointed to investigate a Windows-based security incident. In this process, he employed an Autopsy tool to recover the deleted files from unallocated space, which helps in gathering potential evidence.
Which of the following functions of Autopsy helped Jack recover the deleted files?
Antwort: D
Begründung:
When a file is deleted on common file systems, the operating system typically removes the directory reference and marks the previously used clusters/blocks asunallocated, but the underlying file content may remain on disk until it is overwritten. Digital forensics procedures emphasize that recovering such deleted content often requires examining unallocated space rather than relying only on file system metadata.Autopsy's "Data Carving"function is specifically intended for this purpose: it scans unallocated space (and sometimes slack space) forfile signatures(headers/footers and internal structure patterns) and reconstructs recoverable files even when the original filename, path, or metadata is missing.
This directly matches the scenario: Jack recovered deleted files fromunallocated space, which is the classic use case for carving. The other options in Autopsy support different investigative goals.Timeline analysiscorrelates timestamps from multiple artifacts to reconstruct sequences of activity, but it does not itself reconstruct deleted file content from raw disk areas.Web artifactsfocuses on browser history, downloads, cookies, and related traces.Multimediahelps categorize and analyze media files (e.g., images/videos), but it is not the primary mechanism for recovering deleted data from unallocated space. Therefore, the Autopsy function that enabled the recovery described isData carving (D)
13. Frage
Which of the following file systems of Windows replaces the first letter of a deleted file name with the hex byte code "e5h"?
Antwort: A
Begründung:
InFAT (File Allocation Table)file systems (FAT12/16/32), directory entries are fixed-size records that include an8.3 filename field. When a file is deleted, FAT typically does not immediately erase the file's content; instead, it marks the directory entry as deleted by replacing thefirst character of the filenamewith the special marker byte0xE5(often written asE5h). This is a key forensic behavior because it means the file's metadata entry may still be present in the directory table, and the data clusters may remain recoverable until they are reused and overwritten. Examiners can often reconstruct the original filename's first character only through context or by correlating other artifacts, but the remainder of the directory entry (timestamps, size, starting cluster) can still assist recovery.
The other options do not match this mechanism.NTFSuses Master File Table records and marks deletions differently (file record flags and index changes), not by overwriting the first filename byte with E5h.EFSis an encryption feature layered on NTFS, not a distinct file system deletion marker.FHSis a UNIX/Linux directory layout standard, unrelated to Windows disk structures. Therefore, the correct answer isFAT (A).
