Data destruction process

Physical documents

Physical paper documents containing CONFIDENTIAL information should be destroyed in a ribbon or cross-cut shredder, while any other physical documents containing RESTRICTED information must be shredded with a cross-cut shredder.

Storage devices

Hard drives, USB thumb drives, and other portable storage devices should be securely erased with a single pass of clearing process: random data (/dev/urandom) or zeroed data (/dev/zero) before they are thrown out. Write-once CDs should be broken into pieces or destroyed in the shredder before being thrown out.

Digital data

Digital files containing CONFIDENTIAL information can be simply deleted, while for RESTRICTED data a minimum of one clearing process data must be done over the file.
