  "term": "degauss",
  "field": "Cybersecurity",
  "definition": "1. To reduce the magnetic flux to virtual zero by applying a reverse magnetizing field that is matched to the ISM coercivity.\n\n2. To reduce the magnetic flux to virtual zero by applying a reverse magnetizing field. Also called demagnetizing.\n\n3. To reduce the magnetic flux to virtual zero by applying a reverse magnetizing field. Degaussing any current generation hard disk (including but not limited to IDE, EIDE, ATA, SCSI and Jaz) will render the drive permanently unusable since these drives store track location information on the hard drive.\nAlso called “demagnetizing.”",
