摘要：In digital forensics field, data wiping is considered
one of the anti-forensics’ technique. On the other perspective,
data wiping or data sanitization is the technique used to ensure
that the deleted data are unable to be accessed by any
unauthorized person. This paper introduces a process for data
sanitization from computer hard disk drive. The process was
proposed and tested using commercial data sanitization tools.
Multiple testing has been conducted at accredited digital forensic
laboratory of CyberSecurity Malaysia. The data sanitization
process was performed using overwritten method provided by
state-of-the-art data sanitization tools. For each sanitization tool,
there are options for the wiping technique (overwritten) process.
The options are either to wipe using single pass write or multi
pass write. Logical data checking in the hard disk sector was
performed during pre and post data disposal process for a
proper verification. This is to ensure that the entire sector has
been replaced by data sanitization bit pattern in correspondence
to the selected wiping technique. In conclusion, through the
verification of data sanitization it will improve the process of ICT
asset disposal.
