Purge Media Sanitization Level

A Purge Media Sanitization Level is a media sanitization level that applies physical or logical techniques to protect against laboratory-based data recovery methods.

• AKA: Purge Level, Laboratory-Resistant Sanitization, Advanced Sanitization Level, Forensic-Resistant Erasure.
• Context:
  • It can typically protect against State-of-the-Art Laboratory Attacks using advanced recovery techniques.
  • It can typically target All Addressable Locations including hidden areas and remapped sectors.
  • It can often employ Secure Erase Commands or cryptographic erase for comprehensive sanitization.
  • It can often require Vendor-Specific Commands or specialized tools.
  • It can range from being a Cryptographic Purge Level to being a Overwrite Purge Level, depending on its purge technique type.
  • It can range from being a Block-Level Purge Level to being a Chip-Level Purge Level, depending on its purge granularity.
  • It can range from being a Standard Purge Level to being a Enhanced Purge Level, depending on its purge thoroughness.
  • It can range from being a Automated Purge Level to being a Manual Purge Level, depending on its purge execution method.
  • It can integrate with Hardware Security Modules for cryptographic operations.
  • It can support High-Security Environments requiring forensic-resistant sanitization.
  • ...
• Examples:
  • Purge Level Techniques, such as:
    • ATA Secure Erase Command for SATA drives.
    • Cryptographic Erase for self-encrypting drives.
    • Block Erase Command for solid-state drives.
  • Purge Level Scenarios, such as:
    • External Transfer Sanitization for device leaving organization.
    • Warranty Return Preparation for vendor equipment return.
    • Decommissioning Sanitization for end-of-life systems.
  • ...
• Counter-Examples:
  • Clear Media Sanitization Level, which lacks laboratory attack protection.
  • Destroy Media Sanitization Level, which prevents media reuse.
  • Degaussing Method, which only works on magnetic media.
