Securing Your Web Apps: Defending Against OWASP Top 10 Vulnerabilities

Web security is an ongoing discipline of reducing attack surface area. Vulnerabilities such as Cross-Site Scripting (XSS), Broken Object Level Authorization (BOLA), and Cross-Site Request Forgery (CSRF) continue to compromise enterprise systems. Here is an actionable guide to hardening your web stack.

1. Preventing Cross-Site Scripting (XSS) with Strict CSP

Modern applications should implement Content Security Policy (CSP) HTTP headers to block untrusted script execution:

Content-Security-Policy: default-src 'self'; script-src 'self' https://pagead2.googlesyndication.com; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; img-src 'self' data: https:;

2. Input Sanitization and Parameterized Queries

Always sanitize dynamic HTML inputs and use parameterized queries in ORMs (Prisma, TypeORM) to eliminate SQL injection risks completely.
