SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Secure, reliable backend APIs require consistent application of CORS rules, rate limiting, security headers, input validation, and safe secrets management to prevent common OWASP Top 10 vulnerabilities.

Core Features & Use Cases

  • Guidance on configuring CORS, rate limiting, and security headers for .NET APIs.
  • Best practices for input validation, secrets management, and vulnerability remediation across projects.
  • Use Case: A team adds a security hardening pass to an existing API to reduce exposure during external integrations.

Quick Start

Begin by auditing a .NET API for OWASP Top 10 issues, then enable CORS, configure rate limiting, and apply security headers in your startup code.
