We release patches for security vulnerabilities in the following versions:

Please do not report security vulnerabilities through public GitHub issues.

Instead, please report them via email to: security@delta1.com (or create a private security advisory)

Please include the following information in your report:

1. Type of vulnerability (e.g., SQL injection, XSS, authentication bypass)
2. Full paths of source file(s) related to the vulnerability
3. Location of the affected source code (tag/branch/commit or direct URL)
4. Step-by-step instructions to reproduce the issue
5. Proof-of-concept or exploit code (if possible)
6. Impact assessment - What can an attacker do?
7. Suggested fix (if you have one)

• Acknowledgment: We'll acknowledge your email within 48 hours
• Updates: We'll keep you informed about our progress
• Timeline: We aim to fix critical vulnerabilities within 7 days
• Credit: We'll credit you in the security advisory (unless you prefer to remain anonymous)

Never commit secrets:

# Use environment variables
DATABASE_URL=postgresql://...
JWT_SECRET=...
MPESA_CONSUMER_KEY=...
MPESA_CONSUMER_SECRET=...

# Use .env files (already in .gitignore)
cp .env.example .env

Keep dependencies updated:

# Python
pip install --upgrade pip
pip-audit

# Node.js
npm audit
npm audit fix

# Docker images
docker pull python:3.11-slim
docker pull node:20-alpine

Use secrets management:

# Production: Use AWS Secrets Manager or HashiCorp Vault
# Development: Use .env files (never commit them)

Enable security features:

• Enable HTTPS/TLS 1.3 only
• Set secure headers (HSTS, CSP, X-Frame-Options)
• Enable WAF (Web Application Firewall)
• Use secrets manager (AWS Secrets Manager, Vault)
• Enable database encryption at rest
• Enable VPC/network isolation
• Set up IP whitelisting for admin endpoints
• Enable audit logging

AWS ECS Security Checklist:

# Task definition security
- Use read-only root filesystem
- Drop unnecessary Linux capabilities
- Run as non-root user
- Use secrets from AWS Secrets Manager
- Enable CloudWatch logging
- Use VPC with private subnets
- Enable AWS WAF on ALB

• JWT tokens with RS256 algorithm
• Secure password hashing (bcrypt)
• Role-based access control (RBAC)
• Token expiration (30 minutes)
• Refresh token mechanism

• At Rest: AES-256 encryption for sensitive data
• In Transit: TLS 1.3 for all connections
• Database: Encrypted backups, encrypted connections
• PII: Field-level encryption for customer data

• Rate limiting (planned)
• Input validation (Pydantic schemas)
• SQL injection prevention (parameterized queries)
• XSS protection (React auto-escaping)
• CORS configuration
• Request size limits

• VPC isolation
• Security groups (least privilege)
• Encrypted EBS volumes
• Encrypted S3 buckets
• CloudFront with HTTPS only
• WAF rules (OWASP top 10)

✅ Implemented:

• JWT authentication
• Password hashing
• SQL injection prevention
• XSS protection
• Secure headers
• HTTPS enforcement
• Audit logging

⚠️ Planned (Phase 2):

• Rate limiting per endpoint
• API key management
• Two-factor authentication (2FA)
• IP whitelisting
• Advanced fraud detection
• Security scanning in CI/CD

M-Pesa API:

• Credentials stored in environment variables
• HTTPS-only communication
• Request signing for authenticity
• Callback URL validation

MikroTik RouterOS:

• Encrypted API communication
• Credentials in secrets manager
• Certificate-based authentication
• Limited access via VPN only

1. Report Received → Acknowledged within 48 hours
2. Triage → Severity assessment (Critical/High/Medium/Low)
3. Investigation → Root cause analysis
4. Fix Development → Patch created and tested
5. Release → Security update deployed
6. Disclosure → Public advisory published (after fix)

Critical (CVSS 9.0-10.0):
