Tutorial

Manage secure tokens across your MacFleet devices to enable FileVault encryption, secure boot operations, and cryptographic authentication. This tutorial covers secure token verification, granting, removal, and enterprise-scale token management for enhanced security compliance.

Understanding Secure Tokens

Secure tokens are cryptographic credentials that enable users to perform security-sensitive operations on macOS, particularly essential for FileVault disk encryption:

What are Secure Tokens?

• Cryptographic Keys - Enable access to encrypted storage and security functions
• FileVault Requirement - Required for users to unlock FileVault-encrypted drives
• Bootstrap Tokens - Facilitate secure boot and system recovery processes
• Authentication Bridge - Connect user credentials to system-level security operations
• Legacy Compatibility - Replace older authentication mechanisms in modern macOS

Secure Token Requirements

• macOS 10.13+ - High Sierra and later versions support secure tokens
• Admin Privileges - Granting tokens requires existing admin with secure token
• User Authentication - Both admin and target user passwords required
• System Integrity - SIP (System Integrity Protection) must be properly configured
• Volume Ownership - Users need appropriate volume access permissions

Secure Token Status Verification

Check Individual User Status

#!/bin/bash

# Check secure token status for a specific user
check_user_secure_token() {
    local username="$1"
    
    if [[ -z "$username" ]]; then
        echo "❌ Usage: check_user_secure_token <username>"
        return 1
    fi
    
    # Verify user exists
    if ! id "$username" >/dev/null 2>&1; then
        echo "❌ User '$username' does not exist"
        return 1
    fi
    
    echo "🔍 Checking secure token status for user: $username"
    
    # Check secure token status
    local token_status
    token_status=$(sysadminctl -secureTokenStatus "$username" 2>&1)
    
    if echo "$token_status" | grep -q "ENABLED"; then
        echo "✅ User '$username' has secure token enabled"
        return 0
    elif echo "$token_status" | grep -q "DISABLED"; then
        echo "❌ User '$username' does not have secure token"
        return 1
    else
        echo "⚠️ Unable to determine secure token status for '$username'"
        echo "Output: $token_status"
        return 2
    fi

Important Notes

• macOS Version Requirements - Secure tokens require macOS 10.13 (High Sierra) or later
• Admin Prerequisites - Granting tokens requires an existing admin user with secure token
• Password Security - Both admin and target user passwords must be provided for token grants
• FileVault Integration - Users need secure tokens to unlock FileVault-encrypted volumes
• Enterprise Deployment - Test token operations on individual devices before fleet deployment
• Monitoring - Regular audits ensure compliance with enterprise security policies

Manage secure data erasure and privacy protection across your MacFleet devices using advanced data sanitization systems. This tutorial covers free space erasure, secure deletion, compliance monitoring, and comprehensive data lifecycle management.

Understanding macOS Secure Data Erasure

macOS provides secure data erasure capabilities for privacy and compliance:

• diskutil secureErase - Secure erasure of free space and volumes
• Free Space Erasure - Remove traces of deleted files from disk
• Secure Wipe Levels - Multiple security standards (DoD, DoE, Gutmann)
• Privacy Protection - Prevent data recovery and forensic analysis
• Compliance Requirements - Meet regulatory standards for data destruction

Security Considerations

Data Sanitization Security

• Multi-Pass Overwriting - Use appropriate security levels for data sensitivity
• Verification Procedures - Verify complete erasure and data unrecoverability
• Compliance Standards - Meet regulatory requirements for data destruction
• Chain of Custody - Maintain audit trails and documentation
• Physical Security - Consider physical destruction for highest security needs

Compliance Framework

• GDPR Compliance - Right to erasure and data protection requirements
• HIPAA Medical - Medical record destruction with proper certification
• SOX Financial - Financial data erasure with audit requirements
• Government Standards - FISMA, NIST SP 800-88 for classified data
• Industry Standards - DoD 5220.22-M, Common Criteria for secure erasure

Troubleshooting Guide

Common Issues

Erasure Process Fails

• Check volume is not in use: lsof | grep /Volumes/VolumeName
• Verify sufficient permissions: Run with sudo if needed
• Check disk health: diskutil verifyVolume /Volumes/VolumeName

Slow Erasure Performance

• Higher security levels (3,4) take significantly longer
• SSD vs HDD performance differences
• System load and available resources affect speed

Volume Not Found

• List available volumes: diskutil list
• Check mount points: df -h
• Verify volume name escaping for spaces: Volume\ Name

Diagnostic Commands

# List all volumes
diskutil list

# Check volume information
diskutil info /Volumes/VolumeName

# Check free space
df -h /Volumes/VolumeName

# Monitor erasure progress
sudo fs_usage -w -f diskio diskutil

Important Notes

• Backup Critical Data - Always backup important files before erasure
• Time Requirements - Higher security levels require significantly more time
• Volume Names - Escape spaces in volume names with backslashes
• Security vs Performance - Balance security needs with time constraints
• Verification - Always verify erasure completion for compliance
• Documentation - Maintain proper audit trails and certificates for regulatory compliance

Manage secure file archives across your MacFleet devices with enterprise-grade compression and encryption tools. This tutorial covers password-protected ZIP creation, batch archive operations, security compliance, and comprehensive fleet-wide archive management.

Understanding Secure Archive Management

Secure archive management on macOS involves creating protected compressed files for data transfer, storage, and compliance:

Core Components

• ZIP Compression - Standard archive format with broad compatibility
• Password Protection - AES encryption for archive security
• Batch Operations - Mass archive creation and management
• Integrity Verification - Archive validation and corruption detection
• Compliance Tracking - Audit trails and security reporting

Enterprise Benefits

• Data Security - Protected file transfer and storage
• Storage Optimization - Compressed archives save disk space
• Compliance Requirements - Secure data archival for regulations
• Fleet Management - Standardized archive operations across devices
• Audit Capabilities - Complete tracking of archive operations
