Definition
CSF/LFD monitors suspicious logins and traffic and can temporarily block IP addresses.
What does it mean in practice?
For hosted services, CSF/LFD 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. CSF/LFD 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
