AuthSome is an authentication framework handling sensitive user credentials and session data. Security is our highest priority.

DO NOT open a public GitHub issue for security vulnerabilities.

3. Response Time: We aim to respond within 48 hours
4. Disclosure: We follow coordinated disclosure (90 days)

We use CVSS 3.1 scoring:

• Critical (9.0-10.0): Immediate patch required
• High (7.0-8.9): Patch within 7 days
• Medium (4.0-6.9): Patch within 30 days
• Low (0.1-3.9): Patch in next minor release

• Password Hashing: bcrypt (cost factor 12)
• Session Tokens: Cryptographically secure random (32 bytes)
• Session Storage: Cookie (HttpOnly, Secure, SameSite=Lax) + Redis cache
• Token Expiry: Configurable (default 7 days)
• Refresh Tokens: Rotation on use with family tracking

• Login Attempts: 5 per 15 minutes per IP
• Registration: 3 per hour per IP
• Password Reset: 3 per hour per email
• 2FA Attempts: 5 per 15 minutes per user
• API Endpoints: 100 requests per minute per IP

• Encryption at Rest: Database-level encryption recommended
• Encryption in Transit: TLS 1.3 required in production
• PII Handling: Minimal collection, encrypted storage
• Audit Logging: All authentication events logged
• Secret Management: Environment variables, no hardcoded secrets

• SQL Injection: Parameterized queries (Bun ORM)
• XSS Prevention: Output encoding, CSP headers
• CSRF Protection: SameSite cookies, CSRF tokens
• Path Traversal: Strict path validation
• Command Injection: No shell execution with user input

• Vulnerability Scanning: Daily automated scans
• Dependency Updates: Weekly review and updates
• Supply Chain: SBOM generation, license compliance
• Pinned Versions: Go modules with checksums

• SAST: gosec, golangci-lint with security linters
• Dependency Scanning: govulncheck, trivy, nancy
• Secret Detection: gitleaks pre-commit hooks
• Penetration Testing: Annual third-party assessment
• Security Reviews: Mandatory for all PRs

# Production configuration requirements

Never commit these to version control:

# Required secrets
AUTH_SECRET=<generate with: make generate-secret>
DATABASE_URL=postgresql://...
REDIS_URL=redis://...

# OAuth provider secrets (if used)
GOOGLE_CLIENT_SECRET=...
GITHUB_CLIENT_SECRET=...

# Email/SMS provider keys
SENDGRID_API_KEY=...
TWILIO_AUTH_TOKEN=...

# JWT signing keys
JWT_PRIVATE_KEY_PATH=/path/to/private.pem
JWT_PUBLIC_KEY_PATH=/path/to/public.pem

# Generate secure secrets
make generate-secret

# Generate RSA keys for JWT/OIDC
make generate-keys

# Rotate secrets regularly (quarterly recommended)

-- Use separate database users with minimal privileges
CREATE USER authsome_app WITH PASSWORD '...';
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO authsome_app;

-- Enable SSL connections
ALTER SYSTEM SET ssl = on;

-- Enable audit logging
ALTER SYSTEM SET log_statement = 'mod';

• Deploy behind reverse proxy (Nginx, Caddy)
• Use Web Application Firewall (WAF)
• Enable DDoS protection (Cloudflare, AWS Shield)
• Restrict database access to application servers only
• Use VPC/private networks

Monitor these security events:

• Failed login attempts (5+ in 5 minutes)
• Password reset requests (3+ in 1 hour)
• New user registrations (spike detection)
• API rate limit hits
• Database connection failures
• Unusual geographic access patterns

We use the following tools (see Makefile):

# Run all security checks
make security-audit

# Individual checks
make security-gosec          # Static application security
make security-vuln           # Vulnerability scanning
make security-secrets        # Secret detection
make security-deps           # Dependency audit
make security-licenses       # License compliance

• Sessions are stored in cookies AND Redis for distributed systems
• Session fixation: New session ID on authentication
• Session hijacking: Bind sessions to User-Agent + IP (optional)
• Concurrent sessions: Configurable limit per user

• State parameter: CSRF protection for OAuth flows
• PKCE: Required for public clients
• Token validation: Signature, expiry, audience, issuer
• Provider trust: Only verified providers allowed

• Organization isolation: Row-level security
• Data leakage: Strict org_id validation
• Cross-tenant access: Explicit role checks
• Configuration isolation: Per-org config overrides

• Random generation: crypto/rand (not math/rand)
• Hash algorithms: bcrypt, SHA-256 (no MD5, SHA-1)
• Key derivation: PBKDF2 or Argon2
• Token comparison: constant-time comparison

• Right to erasure: User deletion endpoint
• Data portability: Export user data
• Consent management: Explicit opt-in
• Data minimization: Collect only necessary fields

• Access controls: RBAC with audit logging
• Encryption: TLS + database encryption
• Monitoring: Real-time security alerts
• Incident response: Documented procedures

We address all OWASP Top 10 vulnerabilities:

1. ✅ Broken Access Control → RBAC with policy engine
2. ✅ Cryptographic Failures → Strong encryption, secure key management
3. ✅ Injection → Parameterized queries, input validation
4. ✅ Insecure Design → Security-first architecture
5. ✅ Security Misconfiguration → Secure defaults, config validation
6. ✅ Vulnerable Components → Automated scanning, updates
7. ✅ Authentication Failures → Enterprise-grade auth patterns
8. ✅ Software & Data Integrity → SBOM, checksums, signatures
9. ✅ Security Logging → Comprehensive audit trails
10. ✅ SSRF → URL validation, allowlist approach
