GUIDE

This document outlines the security framework and operational procedures for the system. It covers core security principles, mandatory technical controls, specific methods for preventing common attack vectors, access management configurations, step-by-step incident response plans, and a routine maintenance checklist to ensure ongoing security posture.

ZEE Quiz Application Security Framework app_ver: 1.0.0 doc_ver: A1

1. Core Security Principles

• Least Privilege: Minimal permissions for all system components
• Defense in Depth: Multiple layers of security controls
• Secure by Default: Secure configurations out-of-the-box
• Zero Trust: Verify explicitly, assume breach
• Privacy by Design: Data protection from the start

2. Mandatory Security Controls

Type	Minimum Requirement	Implementation
Authentication	Multi-factor for admin access	OAuth 2.0 + JWT
Authorization	Role-based access control	Casbin
Data Encryption	TLS 1.3 for all communications	Let's Encrypt
Input Validation	Strict type checking & sanitization	Go validator
Logging	Centralized structured logging	Zap + ELK Stack
Monitoring	Real-time security monitoring	Prometheus + Grafana
Secret Management	Secure storage of credentials	HashiCorp Vault
Dependencies	Regular security updates	Dependabot

3. Attack Prevention Matrix

Attack Vector	Prevention Method	Implementation
SQL Injection	Parameterized queries	pgx driver
XSS	Context-aware escaping	html/template
CSRF	Token validation	gorilla/csrf
Brute Force	Rate limiting	Tollbooth
DDoS	WAF + Rate limiting	Cloudflare
Data Leakage	Field-level encryption	libsodium
Broken Auth	Secure session management	scs
Insecure Deserialization	Strict type checking	Go strict unmarshal

4. Access Management

roles:
  admin:
    endpoints:
      - "GET|POST|PUT|DELETE /admin/**"
  user:
    endpoints:
      - "GET /api/profile/**"
      - "POST /api/quiz/**"
  public:
    endpoints:
      - "GET /health"
      - "POST /api/register"
      - "GET /api/quiz/start"

5. CI/CD Security

• Code Scanning: Static application security testing (SAST)
• Dependency Scanning: OWASP Dependency-Check
• Container Scanning: Trivy for container vulnerabilities
• Secrets Detection: Gitleaks for exposed secrets
• Infrastructure as Code: Terraform scanning with Checkov

6. Incident Response Plan

1. Detection & Classification

   • Monitor security events and alerts
   • Classify incident severity (Low, Medium, High, Critical)

2. Containment

   • Isolate affected systems
   • Preserve evidence
   • Temporary mitigation measures

3. Eradication

   • Identify root cause
   • Apply security patches
   • Remove malware/unauthorized access

4. Recovery

   • Restore systems from clean backups
   • Verify system integrity
   • Monitor for recurrence

5. Post-Mortem

   • Document incident details
   • Identify improvements
   • Update security controls

7. Weekly Security Maintenance

• Review and rotate API keys
• Update system packages
• Review security logs
• Backup verification
• Check for security advisories
• Review user access rights
• Test backup restoration
• Scan for vulnerabilities

8. Security Headers

X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Content-Security-Policy: default-src 'self'
Strict-Transport-Security: max-age=31536000; includeSubDomains
Referrer-Policy: strict-origin-when-cross-origin
Permissions-Policy: camera=(), microphone=(), geolocation=()

9. Data Protection

• At Rest: AES-256 encryption for sensitive data
• In Transit: TLS 1.3 for all communications
• In Use: Field-level encryption for PII
• Backup: Encrypted backups with 30-day retention

10. Security Monitoring

• Log Collection: Centralized logging of all system events
• SIEM Integration: Real-time security event monitoring
• Alerting: Immediate notification for critical events
• Audit Trail: Immutable logging of all administrative actions
