OWASP Top 10: A Developer's Practical Guide

The OWASP Top 10 remains the most referenced framework for web application security risks. For development teams, understanding these vulnerabilities at the code level is essential — scanners alone cannot catch logic flaws, broken access controls, or insecure design patterns.

Broken Access Control tops the list for good reason. Always verify authorization server-side on every request. Client-side checks and hidden form fields are not security controls. Implement role-based access control (RBAC) with principle of least privilege and test horizontal and vertical privilege escalation scenarios.

Injection vulnerabilities — SQL, OS command, LDAP — persist because user input is still concatenated into queries and commands. Use parameterized queries, prepared statements, and input validation libraries appropriate to your stack. For NoSQL databases, treat operator injection with equal seriousness.

Security is not a phase at the end of a sprint. Integrate threat modeling into design reviews, add security-focused unit tests, and run SAST/DAST in your CI pipeline. RAVENSECOPS offers secure development training tailored to your technology stack.
