ConfigServe Firewall, known as CSF, is a firewall configuration script created to provide better security for your server while giving you an easy way to use, advanced interface for managing your firewall settings. CSF configures your server’s firewall to reduce public access to services and only allow particular connections, like logging in to FTP, checking your email, or loading your websites.
ConfigServe Firewall comes with a service called Login Failure Daemon, or LFD. LFD monitor your user activity for excessive login failures which are usually seen during brute force attacks. If a large amount of login failures are seen coming from the same IP address, that IP will immediately be temporarily blocked from all services on your server. These IP blocks will automatically expire, but it can be removed manually through the ConfigServer interface in WebHost Manager. CSF also allows you to manually whitelist or blacklist IPs in your firewall, as well as real time monitoring for automatic IP blocks in LFD.
we preinstall ConfigServe Firewall on all servers. Our VPS customers can easily manage the CSF application from inside cPanel/WHM and comes preloaded with our own custom Secured rules.
