How does disk sanitization in ONTAP help to prevent recovery of data?

Applies to

Product Model: FAS and AFF systems
OS: ONTAP 9

Summary

  • The disk sanitization feature in ONTAP removes and prevents data from being recovered on physical media according to NIST SP 800-88r1 guidelines for media sanitization.
  • Disk sanitization is commonly performed in instances where there was either a data spill (classified or sensitive data that ends up in an unsecure location) or when physical media is being returned or removed from production.
  • Knowledge of NetApp disk sanitization helps ensure the sanitization method chosen (Clear, Purge or Destroy) meets the confidentiality needs (low, moderate or high impact) of the operational environment.
