Definition

CAPTCHA helps distinguish a real human from automation in forms and security workflows.

What does it mean in practice?

For hosted services, CAPTCHA matters when identifying threats, limiting access, preserving evidence and verifying that a remediation really worked.

A practical Hostilla.pl example

For a security incident, record the affected account, domain, source IP and timestamp before changing logs or files. CAPTCHA is useful only when it is connected to evidence and a controlled remediation step.

What should you check?

  • the affected service, URL, account and time window
  • server, application, authentication and mail logs
  • known-good backups and the last controlled change
  • least-privilege access, containment and a verification test
