HomeDocsFirewall and Hardening Controls

Firewall Page

The Firewall page exposes a normalized firewall view with rules, blocked IPs, protection settings, and advanced details. Frabs supports UFW directly and can operate safely in iptables-based environments.

Exact Rule Tracking

Firewall actions created by Frabs are tagged and stored with exact rule references. This lets the platform remove or update mitigations reliably instead of guessing which rule to touch.

SSH Hardening

The Hardening page reads and applies real SSH configuration values such as port, password authentication, public key authentication, maximum authentication tries, and login grace time. Frabs validates the config before applying it and rolls back on failure.

Fail2Ban

Fail2Ban settings can be reviewed and updated from Frabs. Changes are applied through the server runtime so the UI reflects real protection state rather than static form values.
