SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps security-minded engineers and developers identify and remediate the most common web vulnerabilities (OWASP Top 10 2021) to reduce risk, speed up security reviews, and improve code quality with repeatable remediation patterns.

Core Features & Use Cases

  • Vulnerability Guidance: Clear patterns for common issues like Broken Access Control, Cryptographic Failures, and Injection to guide audits and secure coding.
  • Remediation Patterns: Concrete safe implementations and secure code examples to prevent regressions.
  • Audit Readiness: Useful as a reference during security certifications, code reviews, and incident investigations.

Quick Start

Run the OWASP Top 10 skill during a security audit to surface high-risk patterns in the codebase and propose concrete fixes for the top 5 vulnerabilities.

FAQPage Schema
How do I identify OWASP Top 10 vulnerabilities in my web application?

OWASP Top 10 vulnerabilities are the most critical web security risks, including broken access control, cryptographic failures, and injection attacks. Use security audits and code reviews to scan for these patterns, then apply detection guidance to surface high-risk issues in your codebase.

What's the best way to fix common web security vulnerabilities during code review?

Follow concrete remediation patterns for each vulnerability type—secure implementations, input validation, authentication checks, and defense-in-depth configurations. Apply prevention checklists across development, testing, and production phases to prevent regressions.

Can I use OWASP Top 10 guidance for security certifications and compliance audits?

Yes. OWASP Top 10 serves as a reference for security certifications, code reviews, and incident investigations. It provides validation criteria and secure coding practices across development, testing, and production phases to meet audit requirements.

How do I assess third-party dependency risks in my application?

Third-party dependency risk assessment is part of OWASP Top 10 scope. Evaluate dependencies for known vulnerabilities, outdated versions, and security misconfigurations as part of your broader security audit and defense-in-depth design.

What authentication and authorization issues should I check for in code reviews?

Broken access control is the top OWASP vulnerability. Check for weak authentication mechanisms, improper authorization logic, session management flaws, and privilege escalation risks using secure coding guidance and example vulnerability cases.

Why is input validation critical for preventing web vulnerabilities?

Input validation and sanitization prevent injection attacks and other code-execution vulnerabilities. OWASP Top 10 guidance covers detection patterns and secure implementations to block malicious input at all application layers.
