We actively maintain and provide security updates for the following versions of this Next.js template:

This template is built on the following stack with their security considerations:

This template includes built-in security features:

• ✅ Environment Variable Validation - Runtime validation of environment variables
• ✅ Type Safety - Full TypeScript coverage
• ✅ Content Security Policy - Configurable CSP headers
• ✅ HTTPS Enforcement - Production HTTPS redirect
• ✅ Dependency Scanning - Regular dependency audits
• ✅ Input Validation - Zod schema validation
• ✅ API Rate Limiting - Configurable rate limits
• ✅ Secure Headers - Security headers via Next.js config

Please report security vulnerabilities through one of the following channels:

1. GitHub Security Advisories (Preferred)

   • Go to the repository's Security tab
   • Click "Report a vulnerability"
   • Fill out the advisory form

2. Email (For sensitive issues)

   • Send details to: [kuliah.informatika01@gmail.com]
   • Use GPG key: [Your GPG Key ID] for encrypted communication

3. Private Issue

   • Create a private issue in the repository
   • Tag with security label

When reporting a vulnerability, please include:

• Description of the vulnerability
• Steps to reproduce the issue
• Potential impact assessment
• Suggested fix (if known)
• Environment details (OS, Node.js version, etc.)

If the vulnerability is accepted:

• We will work on a fix immediately
• You will be credited in the security advisory (unless you prefer anonymity)
• We will coordinate disclosure timeline with you
• A security patch will be released as soon as possible

If the vulnerability is declined:

• We will provide a detailed explanation
• We may suggest alternative solutions or mitigations
• The issue will be closed with reasoning

When using this template, follow these security best practices:

# Use strong, unique values for sensitive data
DATABASE_URL="postgresql://user:password@localhost/db"
NEXTAUTH_SECRET="your-super-secret-key-here"
API_KEY="your-api-key"

# Never commit .env.local or .env.production to version control

// Always validate input data
import { z } from 'zod'

const userSchema = z.object({
  email: z.string().email(),
  password: z.string().min(8)
})

export async function POST(request: Request) {
  const body = await request.json()
  const validatedData = userSchema.parse(body) // Throws if invalid
  // ... rest of your code
}

// next.config.js
const securityHeaders = [
  {
    key: 'Content-Security-Policy',
    value: "default-src 'self'; script-src 'self' 'unsafe-eval'; style-src 'self' 'unsafe-inline';"
  }
]

This template uses:

• Dependabot for automated dependency updates
• npm audit for vulnerability scanning
• Snyk for continuous monitoring (optional)

Run these commands regularly:

# Check for vulnerabilities
npm audit

# Update dependencies
npm update

# Check for outdated packages
npm outdated

The following security headers are configured by default:

• X-Frame-Options: DENY
• X-Content-Type-Options: nosniff
• Referrer-Policy: origin-when-cross-origin
• Permissions-Policy: camera=(), microphone=(), geolocation=()

If implementing authentication:

• Use established libraries (NextAuth.js, Auth0, etc.)
• Implement proper session management
• Use HTTPS in production
• Implement rate limiting
• Validate all user inputs
• Use secure password hashing (bcrypt, argon2)

• Automatic HTTPS
• Environment variable encryption
• DDoS protection
• Edge runtime security

# Use non-root user in Docker
FROM node:18-alpine
RUN addgroup -g 1001 -S nodejs
RUN adduser -S nextjs -u 1001
USER nextjs

Before deploying to production:

• All environment variables are properly set
• No sensitive data in client-side code
• HTTPS is enforced
• Security headers are configured
• Dependencies are up to date
• Input validation is implemented
• Error messages don't leak sensitive information
• Logging doesn't include sensitive data
• Rate limiting is configured
• CORS is properly configured
