11. REASONS FOR PERMANENTLY DELETING DATA
 Prevent Identity Theft by deleting financial
records so can’t be retrieved by crackers
 Secret, private and company information that
should never be retrieved by anyone else
 In case of selling or donating the hard drive or
entire computer and the information shouldn’t
be accessible by anyone
 To comply with data protection by storing
information only for the required time and to re-
assure clients their information will be protected

12. DELETING DATA V.S. DESTROYING DATA
 Deleting Data – if you delete something and
even empty the recycle bin there is still a
residual record left on the computer
 This can be retrieved using hard-drive
restoring software
 Destroying data by using shredding or
degaussing is a permanent method
 The data is unable to be retrieved

13. PERMANENTLY DESTROYING DATA
 Few methods: Shredding, Degaussing and Data
Destruction Utilities
 Shredding – shredding disks like CD/DVD
 Hard/USB Drive destruction – physical
destruction of a drive
 Degaussing – using magnetism on a disk in
random patterns rendering previous data
unrecoverable
 Data Utilities – software utility to carry out
destruction of data
