Definition
A WAF protects web applications from malicious requests, form abuse and known exploit patterns.
What does it mean in practice?
For hosted services, WAF 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. WAF 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
