Spam controls work best in layers. Combine server-side validation, sensible rate limits, and privacy-conscious abuse detection without making legitimate forms unnecessarily difficult. ## Step-by-step instructions 1. Validate all fields on the server and reject unexpected values. 2. Apply request rate limits appropriate to the form. 3. Use a honeypot or time-based check where suitable. 4. Add a challenge only when risk justifies the extra friction. 5. Log abuse patterns without storing unnecessary personal information. 6. Test accessibility and ensure real visitors can still submit successfully. ## Final checks - Test the result in a realistic situation before relying on it. - Keep a note of any settings or decisions that need future review. - Recheck the process when your tools, hosting, or requirements change.

Security action plan

  • Enable multi-factor authentication for privileged accounts and use unique passwords.
  • Remove unused accounts and grant only the permissions each person needs.
  • Patch dependencies and remove components that are no longer maintained.
  • Keep separate backups and periodically test restoring them.
  • Decide who receives incident reports and how access can be revoked quickly.
