________is the erasing of electronic data by overwriting the contents with null values so that the data cannot be recovered.
Encrypting
Degaussing
Erasing
Zeroization
Zeroization occurs when data is electronically erased by overwriting the contents with zeros so the data recovery is not possible. Erasing does not overwrite data. Degaussing destroys rather than overwrites data. Encryption does overwrite the data, but the original data can be recovered with the encryption keys and therefore retains its value to the organization.
