And it also makes data unrecoverable even in laboratory environment.

This method is relatively efficient in purging diskettes, damaged or inoperative media, and media with large storage capacity. Degaussingĭegaussing is a process of exposing the magnetic media to a strong magnetic field of a degausser to disrupt the recorded magnetic domain. Besides, if a complete destruction is not accomplished, there is still possibility of recovering data in laboratory environment. Besides, when the media is disintegrated or shredded, the residues must be reduced to edge dimensions of 5 mm and surface area of 25 mm 2.īecause physical destruction will destroy media, it is not recommended except that the media is not needed anymore. The physical destruction methods include disintegration, pulverization, melting, incineration, and shredding.

It will completely destroy the media and make the data stored on the media unrecoverable even in a laboratory environment. Physical destruction is adopted on the condition that the information has high security categorization. Otherwise, data sanitization should be taken to protect data privacy.ĭata sanitization is achieved through three major methods: physical destruction, degaussing, and data erasure. If information disclosure would have no impact on organizational mission, or would not result in damage to organizational assets, or financial loss or harm to any individuals, data disposal without sanitization could be considered. ATA Security Erasure and Cryptographic Erasureĭata sanitization is defined as a process of deliberately, permanently, and irreversibly removing or destroying the data stored on a memory device (including HHD, SSD, CD/DVD, USB, mobile devices, etc.), which is used to make data unrecoverable to avoid privacy leak.This article will also give you explanations to DoD 5220.22-M method, ATA security erasure, crypto erase, and tell you the differences between wipe, erase, format, and delete. What is data sanitization? What are data sanitization methods? This article will give you answers.
