Getting Started with Web Security

Web security can seem overwhelming, but following a systematic approach makes it manageable. This guide will help you get started.

Step 1: Enable HTTPS

The foundation of web security is HTTPS. Ensure:

Valid SSL/TLS certificate installed

All HTTP traffic redirects to HTTPS

HSTS header configured

Certificate auto-renewal set up

Step 2: Implement Security Headers

Add essential security headers:

**Strict-Transport-Security**: Force HTTPS

**Content-Security-Policy**: Prevent XSS

**X-Frame-Options**: Prevent clickjacking

**X-Content-Type-Options**: Prevent MIME sniffing

Step 3: Secure Cookies

Configure cookies properly:

Set **Secure** flag (HTTPS only)

Set **HttpOnly** flag (no JavaScript access)

Use **SameSite** attribute

Avoid sensitive data in cookies

Step 4: Regular Security Scans

Run security scans regularly:

Check for misconfigurations

Monitor certificate expiration

Review security headers

Test for vulnerabilities

Step 5: Keep Dependencies Updated

Update frameworks and libraries

Monitor security advisories

Use dependency scanning tools

Test updates before deploying

Next Steps

1. Run a security scan to identify issues

2. Fix critical vulnerabilities first

3. Implement missing security headers

4. Set up monitoring and alerts

5. Create a security checklist

Remember: Security is an ongoing process, not a one-time task.
