Supreme Widevine Security Auditor v1.0 - DRM Infrastructure Security Posture Evaluation

[40]

PURPOSE:

• Automated security scoring for Widevine deployments
  
• Risk level assessment and classification
  
• Security best practices validation
  
• Comprehensive audit reporting
  

FEATURES:

•  Automated security scoring (0-100 scale)
  
• Risk level classification (Low, Medium, High)
  
• Security findings and recommendations
  
• TLS configuration validation
  
• Certificate security assessment
  
• Compliance reporting
  

 USAGE:

# Complete security audit
$auditReport = Start-ComprehensiveAudit -TargetIP "192.168.1.100" -Port 8443

# Security posture assessment only
$securityScore = Measure-WidevineSecurityPosture -TargetIP "192.168.1.100" -Port 8443

REQUIREMENTS:

• Widevine_Honeypot_Discovery.ps1 as dependency
  
• PowerShell 5.1+
  
• No additional dependencies
