Zorluk: OrtaMicrosoft Command-Line Tools

An IT support specialist is tasked with ensuring that previously deleted sensitive files on a Windows workstation volume cannot be recovered using forensics tools. The operational files currently on the drive must remain intact, and the volume cannot be formatted. Which of the following command-line utilities and options should the specialist execute?

  1. cipher /w:C:\DataCevap
  2. B
    sfc /purgecache
  3. C
    shred -u -z C:\Data
  4. D
    secpol.msc

Cevap

The command 'cipher /w:C:\Data' is the correct choice because it overwrites unallocated free disk space without erasing active files.
The 'cipher /w' command is specifically designed in Windows to remove data from available unallocated storage space. When run against a path, it allocates memory and writes three passes (zeroes, ones, and random numbers) to all free disk space, ensuring deleted files cannot be recovered while leaving active files intact.

Adım Adım Çözüm

1
Identify the administrative requirement.
The requirement demands wiping unallocated/deleted data space while preserving active files on a Windows volume.
Standard file deletion in Windows only removes directory pointers, leaving raw file data in free space until overwritten.
2
Evaluate native Windows CLI disk sanitization tools.
The 'cipher' utility with the '/w' switch (wipe) fills unused disk space with zeroes, ones, and random numbers.
Executing 'cipher /w:<directory_path>' targeted at the volume or folder path safely sanitizes deallocated clusters without affecting active data.
