Media Sanitization Level

A Media Sanitization Level is a security assurance level that defines the degree of data removal effectiveness for storage media.

• AKA: Sanitization Security Level, Data Erasure Level, Media Clearing Level, Sanitization Assurance Level, Data Removal Level.
• Context:
  • It can typically correspond to Threat Models and adversary capabilitys.
  • It can typically determine Sanitization Method Selection and sanitization tool requirements.
  • It can typically align with NIST SP 800-88 three-tier classification system.
  • It can often dictate Media Reuse Possibility and disposal options.
  • It can often influence Sanitization Cost and time requirements.
  • It can range from being a Basic Media Sanitization Level to being a Maximum Media Sanitization Level, depending on its security assurance degree.
  • It can range from being a Logical Media Sanitization Level to being a Physical Media Sanitization Level, depending on its sanitization approach type.
  • It can range from being a Reversible Media Sanitization Level to being an Irreversible Media Sanitization Level, depending on its data recovery possibility.
  • It can range from being a Quick Media Sanitization Level to being a Comprehensive Media Sanitization Level, depending on its sanitization thoroughness.
  • It can integrate with Risk Assessment Frameworks for appropriate level selection.
  • It can support Compliance Frameworks through defined security standards.
  • ...
• Examples:
  • NIST Media Sanitization Levels, such as:
    • Clear Media Sanitization Level for basic protection needs.
    • Purge Media Sanitization Level for moderate protection needs.
    • Destroy Media Sanitization Level for high protection needs.
  • Alternative Media Sanitization Level Schemes, such as:
    • DoD 5220.22-M Levels for military standard compliance.
    • Commercial Sanitization Levels for industry-specific requirements.
    • International Sanitization Levels for global standard compliance.
  • ...
• Counter-Examples:
  • Data Classification Level, which categorizes information rather than removal effectiveness.
  • Security Clearance Level, which authorizes access rather than sanitization degree.
  • Backup Retention Level, which preserves rather than eliminates data.
