Security isn’t about exotic zero-days for most teams — it’s about consistently doing the fundamentals. The OWASP Top 10 has looked broadly similar for years because the same mistakes keep happening.

The non-negotiables

  • Validate and sanitise every input; use parameterised queries everywhere.
  • Hash passwords with a modern algorithm and enforce HTTPS with HSTS.
  • Set a Content-Security-Policy and the standard security headers.
  • Keep dependencies patched — automate the alerts.
  • Scope permissions tightly and log what matters.

None of this is exotic, and together it removes the low-hanging fruit that automated attacks depend on.
