It provides a robust set of tools to protect your server from unauthorized access, malicious attacks, and other security threats. By installing CSF on your WHM server, you can enhance the security of your websites and ensure the integrity of your server.

CSF comes with a wide range of features and functionalities, including intrusion detection, login authentication, IP reputation monitoring, and more. It allows you to effectively manage and control the network traffic to and from your server, preventing unauthorized access and protecting against common cyber threats.

In this article, we will guide you through the process of installing ConfigServer Security & Firewall on your WHM server. We will cover the installation steps, configuration options, and how to effectively use CSF to enhance the security of your server.

Note: Before proceeding with the installation, it is recommended to have root access to your WHM server and take a backup of your server configuration to ensure the safety of your data.

Step 1: Downloading and Extracting CSF

The first step in installing CSF on your WHM server is to download and extract the CSF package. Here is the detailed process:

• Connect to your WHM server using SSH.
• Download the latest version of CSF by running the following command:

wget https://download.configserver.com/csf.tgz

• Extract the CSF package by running the following command:

tar -xzf csf.tgz

This will create a directory named "csf" containing all the necessary files for the installation.

Step 2: Installing CSF

Once you have downloaded and extracted the CSF package, the next step is to install CSF on your WHM server. Follow the steps below:

• Change to the "csf" directory:

cd csf

• Install CSF by running the installation script:

sh install.sh

The installation script will automatically configure CSF based on your server's specifications.

Step 3: Configuring CSF

After installing CSF, you need to configure the firewall settings to suit your specific requirements. The configuration file for CSF is located at /etc/csf/csf.conf. Here are some essential configurations you may want to consider:

• Allowing Incoming and Outgoing Traffic: By default, CSF blocks all incoming and outgoing traffic. If you want to allow specific ports or IP addresses, you can modify the following settings in the csf.conf file:

Configuration	Description
TCP_IN	Specify the ports you want to allow for incoming TCP traffic.
TCP_OUT	Specify the ports you want to allow for outgoing TCP traffic.
UDP_IN	Specify the ports you want to allow for incoming UDP traffic.
UDP_OUT	Specify the ports you want to allow for outgoing UDP traffic.
ICMP_IN	Specify the ICMP types you want to allow for incoming traffic.
ICMP_OUT	Specify the ICMP types you want to allow for outgoing traffic.
TCP6_IN	Specify the ports you want to allow for incoming IPv6 TCP traffic.
TCP6_OUT	Specify the ports you want to allow for outgoing IPv6 TCP traffic.
UDP6_IN	Specify the ports you want to allow for incoming IPv6 UDP traffic.
UDP6_OUT	Specify the ports you want to allow for outgoing IPv6 UDP traffic.
ICMP6_IN	Specify the ICMPv6 types you want to allow for incoming traffic.
ICMP6_OUT	Specify the ICMPv6 types you want to allow for outgoing traffic.

To allow incoming and outgoing traffic on specific ports, you can add the desired ports to the respective configuration variables. For example, to allow incoming traffic on port 80 (HTTP), you would add the following line:

TCP_IN = "80"

To allow incoming and outgoing traffic for specific IP addresses, you can use the ACCEPT directive. For example, to allow incoming traffic from IP address 192.0.2.1, you would add the following line:

ACCEPT     -    192.0.2.1

Make sure to save the changes to the csf.conf file after making the necessary configurations.

Step 4: Starting and Stopping CSF

Once you have configured CSF, you can start it by running the following command:

csf -s

This will activate CSF and apply the configured firewall rules.

If you need to stop CSF temporarily, you can use the following command:

csf -f

To disable CSF permanently, you can run the following command:

csf -x

Step 5: Configuring Additional Security Features

CSF provides additional security features that you can configure according to your requirements. Some of these features include:

• Login Failure Detection (LFD): LFD is a feature in CSF that monitors login attempts on your server and detects failed login attempts. It can automatically block IP addresses that exceed a certain threshold for failed login attempts. You can configure LFD settings in the csf.conf file, such as the maximum number of failed login attempts allowed and the duration of the block.
• SYN Flood Protection: CSF can protect your server against SYN flood attacks. SYN flood attacks aim to overwhelm a server's resources by sending a large number of SYN requests. CSF uses SYNPROXY to detect and mitigate SYN flood attacks. You can enable SYN flood protection by setting the SYNFLOOD variable to "1" in the csf.conf file.
• Connection Tracking: Connection tracking allows CSF to track and monitor network connections made to and from your server. It helps in detecting suspicious or malicious activities. You can enable connection tracking by setting the CT_LIMIT variable to a value greater than zero in the csf.conf file.

Enabling and Configuring LFD

To enable and configure LFD, you can follow these steps:

• Open the csf.conf file:

vi /etc/csf/csf.conf

• Set the following variables to "1" to enable LFD:

LF_DAEMON = "1"
LF_SSHD = "1"
LF_FTPD = "1"
LF_POP3D = "1"
LF_IMAPD = "1"
LF_HTACCESS = "1"

• Save the changes and exit the file.

These settings will enable LFD and configure it to monitor failed login attempts on various services such as SSH, FTP, POP3, IMAP, and .htaccess files.

After making the changes, you need to restart CSF for the new configurations to take effect by running the following command:

csf -r
