Data Protection and Security

Follow these guidelines to maximize data protection and security:

  • Back up important data using devices such as external hard drives or USB storage devices. If possible, store the backed-up data in a second, off-site, secure location.

  • Use data encryption software to keep confidential information on hard drives secure.

  • Hard drives are often used to store sensitive information. To protect this information from unauthorized disclosure, hard drives should be sanitized prior to being reused, decommissioned, or disposed.

    • If you do not physically destroy a decommissioned drive, use disk-wiping tools such as the Oracle Solaris format(1M) command to completely erase all data from the disk drive. Alternatively, you can use physical degaussing tools, if appropriate and available.

    • Organizations are strongly encouraged to refer to their data protection policies to determine the most appropriate method to sanitize hard drives.

  • When disposing of an old hard drive, physically destroy the drive if possible. Information can still be recovered from a drive after files are deleted or the drive has been reformatted. Deleting files or reformatting the drive removes only the address tables on the drive. In some cases, the information contained on the hard drives is of such sensitivity that the only proper sanitation method is physical destruction of the hard drive by means of pulverization or incineration.


Caution  -  Disk-wiping software might not be able to delete some data on modern hard drives, especially solid state drives (SSDs), due to the way that they manage data access.
