Shoonya Wipe - NIST SP 800-88r2 Compliance Guide

Overview

Shoonya Wipe has been fully updated to comply with NIST Special Publication 800-88r2, "Guidelines for Media Sanitization." This document outlines how the software implements each required NIST guideline.

NIST Compliance Implementation

Section 1: Core Wiping Methods

Rule 1.1: Clear Method Implementation ✅

• What it is: Clear uses software to overwrite data, protecting against simple data recovery methods
• Implementation:
  • Single-pass overwrite (NIST recommends against multi-pass methods)
  • Warning displayed for SSD limitations (spare storage areas may not be reached)
  • Appropriate for low-sensitivity data staying in physical control

Rule 1.2: Purge Method Implementation ✅

• What it is: Purge uses advanced techniques to make data recovery infeasible even with lab equipment
• Implementation:
  • SSD Secure Erase: Uses drive's built-in sanitization commands
  • Cryptographic Erase: Erases encryption keys to make data unreadable
  • Automatic technique selection based on device type and encryption status

Rule 1.3: Destroy Method Recommendation ✅

• What it is: Physical destruction makes data recovery impossible
• Implementation:
  • Software cannot physically destroy drives
  • Provides detailed recommendations for physical destruction methods
  • Suggests certified destruction services and proper documentation

Section 2: AI Engine and User Guidance

Rule 2.1: NIST Decision Flowchart ✅

• Implementation: Complete AI-guided decision process
• Questions asked:
  1. Will the drive be reused?
  2. What is the data sensitivity level (Low, Moderate, High)?
  3. Will the drive leave your physical control?
• Decision logic: Follows official NIST flowchart for method selection

Rule 2.2: Cryptographic Erase Rules ✅

• Safety checks:
  • Warns against CE if data was saved before encryption was enabled
  • Recommends CE only if drive was always encrypted from the start
  • Validates encryption status before allowing CE

Section 3: Verification and Checking

Rule 3.1: Sanitization Verification ✅

• Implementation:
  • Checks completion status from drive after wipe commands
  • Reports errors and problems to user
  • Verifies successful completion before marking as complete

Rule 3.2: Method Validation ✅

• Implementation:
  • Warns users about inappropriate method choices
  • Validates device compatibility with chosen techniques
  • Provides guidance on better alternatives

Section 4: Digital Certificate Rules

Rule 4.1: Required Certificate Fields ✅

All NIST-required fields are included in certificates:

Required Fields:

• ✅ Manufacturer
• ✅ Model
• ✅ Serial Number
• ✅ Media Type (e.g., magnetic, flash memory)
• ✅ Sanitization Method (Clear, Purge, Destroy)
• ✅ Sanitization Technique (Overwrite, Crypto Erase, etc.)
• ✅ Tool Used (Shoonya Wipe and version number)
• ✅ Verification Method (e.g., status check)
• ✅ Person's Name, Title, and Date

Additional Fields:

• Device Path
• Device Size
• Verification Status
• Completion Time
• Certificate ID
• NIST Compliance Statement

Usage Examples

CLI Interface

# Run NIST-compliant CLI
python main.py cli

# The system will:
# 1. Display available devices
# 2. Run NIST decision flowchart
# 3. Execute appropriate sanitization method
# 4. Verify completion
# 5. Generate NIST-compliant certificate

Web Interface

# Run NIST-compliant web GUI
python main.py web

# Access at http://localhost:5000
# Features:
# - Device selection
# - NIST compliance settings form
# - AI-guided method selection
# - Real-time progress tracking
# - NIST-compliant certificate generation

NIST Decision Process

The software implements the official NIST decision flowchart:

1. Will the drive be reused?

   • No → Recommend DESTROY method
   • Yes → Continue to next question

2. What is the data sensitivity level?

   • Low + Stays in control → CLEAR method
   • Low + Leaves control → PURGE method
   • Moderate/High → PURGE method

3. Will the drive leave physical control?

   • Yes → PURGE method required
   • No → Method depends on sensitivity

Compliance Verification

Certificate Verification
