What problem does it solve?

OWASP Top 10 guidance helps developers and security teams identify and mitigate common web app vulnerabilities early in the development cycle, reducing risk and audit findings.

Core Features & Use Cases

  • Threat modeling basics and a structured approach to identifying risks.
  • Concrete code patterns to mitigate XSS, SQL injection, CSRF, SSRF, misconfigurations, and insecure authentication.
  • Guidance on secure headers, input validation, output encoding, and secure authentication practices for real-world projects.

Quick Start

Analyze a new web app and implement OWASP-aligned mitigations across input handling, session management, and security headers.

FAQPage Schema
How do I mitigate OWASP Top 10 vulnerabilities like XSS and CSRF in my web app?

To mitigate OWASP Top 10 vulnerabilities like XSS and CSRF, apply concrete code patterns for input validation, output encoding, and security headers configuration including CSP and HSTS across your APIs and user interfaces.

What is the best way to implement threat modeling for web application security?

Threat modeling for web application security involves a structured approach to identifying risks early in the development cycle, covering basics like secure authentication, SSRF protections, and session management before implementation.

How do I configure security headers like CSP and HSTS to protect web applications?

Configuring security headers like CSP and HSTS protects web applications by enforcing strict content policies and secure connections, directly mitigating common injection flaws and protocol downgrade attacks.

Can I use OWASP threat modeling guidance for securing APIs as well as user interfaces?

Yes, OWASP threat modeling guidance applies to securing both APIs and user interfaces by implementing consistent input validation, output encoding, and secure authentication practices across all application endpoints.

Why does my web application still have SSRF vulnerabilities after implementing basic input validation?

SSRF vulnerabilities often persist because basic input validation is insufficient without dedicated SSRF protections, which require strict network-level controls and concrete code patterns to validate server-side resource requests.

Do I need to perform secure coding reviews to prevent SQL injection and misconfigurations?

Yes, performing secure coding reviews is necessary to identify and mitigate SQL injection and misconfigurations, using practical code patterns and threat modeling to reduce audit findings early in the development cycle.
