Security Policy

🛡️ Enterprise Security Framework

This document outlines the security policies, procedures, and guidelines for the Enterprise Hyperledger Fabric Supply Chain Platform. We take security seriously and are committed to maintaining the highest standards of security for our enterprise-grade blockchain platform.

🚨 Reporting Security Vulnerabilities

Immediate Response Required

If you discover a security vulnerability, please report it immediately through one of these channels:

What to Include in Your Report

  3. Reproduction Steps: Step-by-step instructions to reproduce
  4. Proof of Concept: Code or screenshots demonstrating the issue
  5. Suggested Fix: If you have recommendations for mitigation
  6. Environment Details: Version, configuration, and setup details

Response Timeline

We are committed to rapid response:

  • Initial Acknowledgment: Within 24 hours
  • Triage and Assessment: Within 72 hours
  • Status Updates: Every 7 days until resolution
  • Resolution Timeline: Based on severity (see below)

🔒 Security Standards & Compliance

    - single_sign_on: enterprise_integration

  session_management:
    timeout: 30_minutes
    refresh_token: 24_hours
    max_concurrent_sessions: 3

authorization:
  model: "RBAC + ABAC"
  policies:
    - principle_of_least_privilege
    - separation_of_duties
    - zero_trust_architecture

Network Security

  • Firewall Rules: Strict ingress/egress controls
  • Network Segmentation: Isolated network zones
  • DDoS Protection: Multi-layer protection
  • Intrusion Detection: Real-time monitoring
  • Certificate Pinning: API and service communications

🎯 Threat Model

Assets Protected
