OWASP Top 10

The reference list of the most common web vulnerabilities: broken access control, injection, insecure design and more. A WAF helps, but most fixes belong in the code.

Where it shows up in real systems

  • Web application firewall

    Managed rules stop SQL injection, XSS and known bots. Stricter rule sets block more attacks but also some legitimate users, which is why teams tune them in count mode first.

    In production: AWS WAF, Cloudflare WAF, Azure WAF, ModSecurity
