Security in Modern Web Applications

Introduction

Web security should be at the top of every developer's priority list. In this article, we explore best practices for protecting your modern web applications.

OWASP Top 10

The most critical security risks published by OWASP (Open Web Application Security Project):

1. Injection - SQL, NoSQL, OS injections
2. Broken Authentication - Weak password policies
3. Sensitive Data Exposure - Unencrypted data transfer
4. XML External Entities (XXE) - XML parsing vulnerabilities
5. Broken Access Control - Authorization deficiencies

Content Security Policy (CSP)

CSP headers provide a strong defense layer against XSS attacks:

• Only allow scripts from trusted sources
• Limit inline scripts
• Define a reporting endpoint

Conclusion

Security is not a one-time process but a continuous journey. Protect your applications with regular security audits and updates.
