Version: 1.0.0
Last Updated: 2025-01-26
Status: Active


🎯 OVERVIEW

StillMe AI Framework implements comprehensive security measures to protect users, data, and systems. This document outlines our security policies, procedures, and best practices.


πŸ›‘οΈ SECURITY PRINCIPLES

1. Defense in Depth

  • Multiple layers of security controls
  • Fail-safe defaults
  • Principle of least privilege

2. Privacy by Design

  • Data minimization
  • Encryption by default
  • User consent required

3. Transparency & Accountability

  • Open security practices
  • Regular security audits
  • Incident response procedures

πŸ” AUTHENTICATION & AUTHORIZATION

Authentication

  • JWT Tokens: Secure token-based authentication
  • Token Expiry: 1 hour default, 24 hours refresh
  • Algorithm: HS256 with secure key rotation
  • Multi-Factor: Optional 2FA support

Authorization

  • Role-Based Access Control (RBAC): Granular permissions
  • API Keys: Secure API access
  • Session Management: Secure session handling
  • Rate Limiting: Protection against abuse

Configuration

# config/security_config.json
authentication:
  jwt_secret: "auto_generated_secure_key"
  token_expiry: 3600
  refresh_token_expiry: 86400
  algorithm: "HS256"

πŸ”’ ENCRYPTION & DATA PROTECTION

Encryption Standards

  • Algorithm: AES-256-GCM
  • Key Rotation: Every 24 hours
  • Salt Length: 32 bytes
  • Transport: TLS 1.2+ required

Data Protection

  • At Rest: All sensitive data encrypted
  • In Transit: TLS encryption required
  • In Memory: Secure memory handling
  • Backup: Encrypted backups only

PII Protection

Responsible Disclosure Policy

We take security seriously and appreciate responsible disclosure of vulnerabilities. If you discover a security vulnerability, please follow these guidelines:

How to Report:

  1. Email: [email protected] (or create a private security advisory on GitHub)
  2. Subject: [SECURITY] Brief description of vulnerability
  3. Include:
    • Description of the vulnerability
    • Steps to reproduce
    • Potential impact
    • Suggested fix (if any)
    • Your contact information

What to Expect:

  • Response Time: We will acknowledge receipt within 48 hours
  • Initial Assessment: Within 7 days
  • Fix Timeline: Depends on severity (Critical: <7 days, High: <30 days, Medium: <90 days)
  • Disclosure: Public disclosure after fix is deployed (minimum 90 days from report)
  • Credit: We will credit you in security advisories (unless you prefer to remain anonymous)

What NOT to Do:

  • ❌ Do NOT publicly disclose before we've had time to fix
  • ❌ Do NOT access or modify data that doesn't belong to you
