In addition, the overwrite patterns can be adjusted and a random pattern can be used to improve data security.įully complies with the security specification 5220.22M for data sanitization from the US Department of Defense but adds 7 times override to improve security. Hard disk means three times per bit completely overwrite and then verify once (check for result). The 5220.22M data sanitization standard for overwriting a This method complies with the security specification 5220.22M for data removal from U.S. To ensure that all data has been permanently removed, our Erasers offer the following There are a large number of different Erase standards, such as Simply formatting a hard drive is not sufficient to permanently delete all data.

To ensure that no data fragments remain on a hard disk when reused, appropriate measures must be taken. A more practical example of aĭata security policy and classification in risksĬan be found on the Stanford University website. The following flow chart is taken from the National Institute of Standards and Technology 'Guidelines for Media Sanitization' Stays within the organization can be handled differently than a carrier with sensitive information leaving the organization. To select the right method of data destruction it is important to consider a number of things Where does the data carrier go and what security classification does the information have on the data carrier? A data carrier with low risk information that

This makes it necessary to rethink how the information on data carriers should be erased before they leave the organization.

In addition to the traditional hard drive, we increasingly use SSD's, USB drives, memory cards, mobile phones, etc. Where in the past everything was written on magnetic media, this is no longer the case. The amount of data we store continues to grow.
