A firewall is used in the computer network security system that used to monitor the incoming and outgoing network traffic based on security protocols. And it is able to control the network traffic. A firewall acts as a barrier to protect a website from unsecured resources.

A firewall is a vital piece of internet/network security. To prevent unauthorized internet user or hacker to access networks which are connected to the Internet. The firewall monitors the incoming and outgoing network packets allow the legitimate one to access the network. It illustrates the boundary or a wall to keep the network in the secure zone. The firewall is categorized as the network firewalls or host-based firewall. The Firewall has individual protocols and it follows to allow access for the particular packets in the network.


Login Failure Daemon (lfd) is a process that runs all the time and continuously (every second) that it scans the latest log file entries for login attempts against your server that continuously fail within a short period of time. Such attacks are also called as “Brute-force attacks” and the daemon process responds very quickly to such patterns and blocks offending IP’s quickly.

Steps to disable all LFD email Alerts:

1) Login to WHM.

2) Click on “ConfigServer Security & Firewall” under “Plugin”  section in your WHM.


3) Click on “Firewall Configuration” button to edit the CSF configuration file under the Firewall.Firewall-configuration

4) The “LF_EMAIL_ALERT” will be available on the configuration file and change it from “On” to “Off” button to disable all cPanel LFD Alerts on the WHM.LFD-email-alert

5) Click on the “Change” button to save the changes on the Firewall.Change

We need to restart csf and lfd (Login Failure Daemon) services to enable all changes that we made in the above steps. So click on the option of “Restart csf+lfd” button al the last of firewall configuration to restart both the services. Now the alerts of the LFD will get disabled on the firewall of the server.

We hope that this tutorial will help you to Disable All cPanel LFD (Login Failure Daemon) Alerts. For more information, follow us via social media like Facebook and Twitter.
