Code Security
Practical guide covering code-level security — secrets leak prevention, dependency hardening, static analysis, authentication patterns, CI/CD pipeline security, and a comprehensive audit checklist.
Based on OWASP Top 10 (2026), OWASP ASVS 5.0, AppSec 50-Point Audit, and modern DevSecOps practices.
