Normally deleting files just marks space that the files were using as available. It does not actually remove data. Someone else who is assigned the available space could easily retrieve the data. Even after disks have been overwritten with new data, it may still be possible to determine what was there before by physically inspecting the magnetic surface with special tools.
There are four ways to prevent the inadvertent transfer of data that should be kept private when a computer is transferred to someone else or discarded:
- Only save private data on protected disk drives.
Information Technology operates computers that provide disk drives for this purpose. This is the preferred method for dealing with reports generated by Banner.
- Encrypt all private data written to disks.
The free open source program VeraCrypt allows a section of a hard disk to be treated as special disk drive on which files are automatically encrypted before they are saved. A password of your choice is required to map the encrypted disk drive. Once the encrypted disk drive has been mapped, it behaves just like any other disk drive attached to your computer.
This method has the advantage of protecting private information while your computer is in use as well as after it is discarded. Information Technology recommends that VeraCrypt be used to protect data on laptops and computers in insecure areas. If you misplace your VeraCrypt password, the data is irretrievable. IT cannot recover the password or the encrypted data.
- "Scrub" disk areas that may have contained private data before transferring or discarding a computer.
The free open source DBAN program can be used to overwrite all hard disks on a computer. This eliminates software as well as data. It should be used to completely clean hard disks before a computer is sold or discarded.
- Physically altering the media.
Physical destruction of the media is the only method other than encryption that is suitable for preventing access to private information stored on CDs and DVDs. It can also be used for hard disks and other magnetic media. Magnetic media can also be altered by re-aligning magnetic domains in the material with a process known as "degaussing."
