Complete Website Security Implementation Checklist

Every day, thousands of websites get compromised because of basic security oversights. The problem isn't that these vulnerabilities are hard to fix. It's that most teams don't know where to start or what to prioritize.

Website security isn't optional anymore. It's essential for protecting your users, your data, and your business reputation. But implementing security doesn't have to be overwhelming.

If you're not sure where to start or want to make sure you haven't missed anything important, this checklist will help you implement the security measures that actually matter. Use it to build a security foundation that protects your users and your business without overwhelming your development team.

Quick Start: Priority Security Implementation

Quick Wins (Implement These First)

1. Enable HTTPS (2-4 hours)

# Redirect HTTP to HTTPS
server {
    listen 80;
    server_name example.com;
    return 301 https://$server_name$request_uri;
}

2. Add Essential Security Headers (1-2 hours)

add_header X-Content-Type-Options nosniff;
add_header X-Frame-Options DENY;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";

3. Secure Cookies (1-2 hours)

// Set secure cookie flags
res.cookie('sessionId', value, {
  httpOnly: true,
  secure: true,
  sameSite: 'strict',
  maxAge: 3600000
});

Complete Security Implementation Checklist

1. Transport Layer Security (TLS/HTTPS)

Enable HTTPS Everywhere

• Obtain valid SSL/TLS certificate from trusted Certificate Authority
• Configure HTTPS redirects (HTTP → HTTPS)
• Implement HSTS (HTTP Strict Transport Security) header
• Set appropriate HSTS max-age (minimum 1 year)
• Include HSTS preload directive for major browsers
• Verify certificate chain is complete and valid
• Check certificate expiry dates and set up renewal alerts

TLS Configuration

• Disable TLS 1.0 and 1.1 (use only TLS 1.2 and 1.3)
• Configure strong cipher suites
• Enable Perfect Forward Secrecy (PFS)
• Implement OCSP stapling
• Configure Certificate Authority Authorization (CAA) records
• Test TLS configuration with tools like SSL Labs

Implementation Example:

# Nginx TLS Configuration
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384;
ssl_prefer_server_ciphers off;
ssl_session_cache shared:SSL:10m;
ssl_session_timeout 10m;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

2. Security Headers Implementation

Content Security Policy (CSP)

• Implement CSP header with appropriate directives
• Use nonces or hashes for inline scripts/styles
• Avoid 'unsafe-inline' and 'unsafe-eval' directives
• Configure frame-ancestors directive
• Set up CSP reporting endpoint
• Test CSP in report-only mode before enforcement

CSP Implementation Example:

Content-Security-Policy: default-src 'self'; script-src 'self' 'nonce-{random}'; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' https://fonts.gstatic.com; connect-src 'self' https://api.example.com; frame-ancestors 'none'; report-uri /csp-report

Additional Security Headers

• Implement X-Frame-Options or CSP frame-ancestors
• Set X-Content-Type-Options: nosniff
• Implement Referrer-Policy header
• Set Permissions-Policy header
• Configure Cross-Origin-Embedder-Policy (COEP)
• Set Cross-Origin-Opener-Policy (COOP)
• Implement Cross-Origin-Resource-Policy (CORP)

Complete Headers Example:

X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Referrer-Policy: strict-origin-when-cross-origin
Permissions-Policy: geolocation=(), microphone=(), camera=()
Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Resource-Policy: same-origin

3. Cookie Security Configuration

Secure Cookie Settings

• Set Secure flag for all cookies
• Implement HttpOnly flag for session cookies
• Configure SameSite attribute (Strict, Lax, or None)
• Set appropriate cookie expiration times
• Use partitioned cookies for third-party contexts
• Implement cookie prefixing (__Secure-, __Host-)
• Regular cookie audit and cleanup

Cookie Implementation Example:

Set-Cookie: sessionId=abc123; Secure; HttpOnly; SameSite=Strict; Max-Age=3600; Path=/
Set-Cookie: __Secure-authToken=xyz789; Secure; HttpOnly; SameSite=Lax; Max-Age=86400; Path=/; Domain=.example.com

4. CORS (Cross-Origin Resource Sharing) Security

CORS Configuration

Proper CORS configuration requires configuring Access-Control-Allow-Origin appropriately and setting Access-Control-Allow-Credentials only when necessary. Define Access-Control-Allow-Methods explicitly and configure Access-Control-Allow-Headers to specify which headers are allowed. Set Access-Control-Max-Age for preflight caching to improve performance, implement proper Vary header with Origin to ensure correct caching behavior, and test CORS configuration thoroughly to prevent security bypasses.

CORS Implementation Example:

Access-Control-Allow-Origin: https://trusted-domain.com
Access-Control-Allow-Methods: GET, POST, PUT, DELETE
Access-Control-Allow-Headers: Content-Type, Authorization
Access-Control-Allow-Credentials: true
Access-Control-Max-Age: 86400
Vary: Origin

5. Email Security Configuration

Email Authentication

• Implement SPF (Sender Policy Framework) records
• Configure DKIM (DomainKeys Identified Mail) signatures Set up DMARC (Domain-based Message Authentication) policy to control how email authentication failures are handled, monitor email authentication reports to track policy effectiveness, configure BIMI (Brand Indicators for Message Identification) for brand protection, and set up MTA-STS (Mail Transfer Agent Strict Transport Security) to enforce secure email transmission.

Email Security DNS Record Examples:

SPF Record:
example.com. IN TXT "v=spf1 include:_spf.google.com ~all"

DKIM Record:
default._domainkey.example.com. IN TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC..."

DMARC Record:
_dmarc.example.com. IN TXT "v=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1"

6. Input Validation and Output Encoding

Input Validation

Implement comprehensive server-side input validation using whitelist validation where possible to ensure only expected data types, lengths, and formats are accepted. Implement rate limiting for forms to prevent abuse, use parameterized queries for databases to prevent SQL injection, validate file uploads for type, size, and content to prevent malicious file uploads, and implement CAPTCHA for sensitive forms to prevent automated attacks.

Output Encoding

Encode output based on context (HTML, URL, JavaScript, CSS) using appropriate encoding functions to prevent XSS attacks. Implement Content-Type headers correctly to ensure browsers interpret content properly, sanitize user-generated content to remove potentially malicious elements, and use templating engines with auto-escaping to automatically handle output encoding.

7. Authentication and Authorization

Authentication Security

Implement strong password policies and use multi-factor authentication (MFA) to enhance account security. Implement account lockout mechanisms to prevent brute force attacks, use secure session management to protect user sessions, and implement proper logout functionality to ensure sessions are properly terminated. Use OAuth 2.0 or OpenID Connect for third-party authentication and implement password reset securely to prevent account takeover attacks.

Authorization Controls

Implement the principle of least privilege and use role-based access control (RBAC) to ensure users only have access to resources they need. Implement proper access controls throughout the application, conduct regular access review and cleanup to remove unnecessary permissions, use JWT tokens securely with proper validation and expiration handling, and implement API authentication to secure API endpoints.

8. Database Security

Database Configuration

Use parameterized queries to prevent SQL injection attacks and implement database encryption at rest to protect sensitive data. Use encrypted connections to the database and apply regular database security updates to patch vulnerabilities. Implement database access controls to restrict user permissions, use database monitoring and logging to track access and detect anomalies, and maintain regular database backups with encryption to ensure data recovery capabilities.

9. API Security

API Protection

Implement API authentication using API keys, OAuth, or JWT tokens to secure API endpoints and use HTTPS for all API communications. Implement rate limiting and throttling to prevent abuse and validate all API inputs to prevent injection attacks. Implement proper error handling to avoid information disclosure and implement API monitoring and logging to track usage and detect security incidents.

10. Modern Framework Security Implementation

React/Next.js Security

// Next.js security configuration
// next.config.js
module.exports = {
  async headers() {
    return [
      {
        source: '/(.*)',
        headers: [
          {
            key: 'X-Frame-Options',
            value: 'DENY'
          },
          {
            key: 'X-Content-Type-Options',
            value: 'nosniff'
          },
          {
            key: 'Referrer-Policy',
            value: 'strict-origin-when-cross-origin'
          },
          {
            key: 'Content-Security-Policy',
            value: "default-src 'self'; script-src 'self' 'unsafe-eval'; style-src 'self' 'unsafe-inline'"
          }
        ]
      }
    ]
  }
}

// React security best practices
// Use environment variables for sensitive data
const API_URL = process.env.NEXT_PUBLIC_API_URL
const API_KEY = process.env.API_KEY // Server-side only

// Implement proper input validation
import DOMPurify from 'dompurify'

const sanitizeInput = (input) => {
  return DOMPurify.sanitize(input)
}

// Secure cookie handling
import { cookies } from 'next/headers'

const setSecureCookie = (name, value) => {
  cookies().set(name, value, {
    httpOnly: true,
    secure: process.env.NODE_ENV === 'production',
    sameSite: 'strict',
    maxAge: 60 * 60 * 24 * 7 // 7 days
  })
}

export default {
  security: {
    headers: {
      crossOriginEmbedderPolicy: process.env.NODE_ENV === 'production' ? 'require-corp' : 'unsafe-none',
      contentSecurityPolicy: {
        'base-uri': ["'self'"],
        'font-src': ["'self'", 'https:', 'data:'],

        'script-src-attr': ["'none'"],
        'style-src': ["'self'", 'https:', "'unsafe-inline'"],
        'script-src': ["'self'", 'https:']
      }
    }
  }
}

// Vue security middleware
export default function ({ $axios, $auth }) {
  $axios.onRequest(config => {
    // Add CSRF token to requests
    if ($auth.loggedIn) {
      config.headers['X-CSRF-Token'] = $auth.getToken('local')
    }
    return config
  })
}

Common Implementation Issues & Solutions

Issue: HTTPS redirect not working

Solution: Check server configuration and DNS settings

# Ensure proper redirect configuration
server {
    listen 80;
    server_name example.com;
    return 301 https://$server_name$request_uri;
}

Issue: Security headers not appearing

Solution: Check server configuration and test with curl

# Test headers
curl -I https://your-site.com | grep -i "strict-transport-security\|x-frame-options\|content-security-policy"

Issue: CSP blocking legitimate resources

Solution: Use nonces or allow specific domains

# Use nonces for inline scripts
add_header Content-Security-Policy "script-src 'self' 'nonce-$request_id'";
