Introduction

Suricata is an open-source network threat detection engine that can function as an IDS, IPS, and Network Security Monitoring (NSM) tool. With Kali Purple, you have a powerful platform at your fingertips for enhancing your network security. In this guide, we’ll walk you through the steps to install and configure Suricata, complete with examples to make the process easy and intuitive.

Step 1: Update Your System 🔄

Before we dive into installing Suricata, let’s ensure your Kali Purple system is up to date. Running updates regularly helps you avoid potential compatibility issues.

sudo apt update && sudo apt upgrade -y

Step 2: Install Suricata 📦

Suricata is available directly from the Kali Linux repositories, making installation a breeze.

sudo apt install suricata -y

Step 3: Verify the Installation ✅

Let’s confirm that Suricata has been installed correctly. This step will give you peace of mind knowing everything is in place.

suricata --build-info

This command provides detailed information about your Suricata installation, including the version and compile-time options.

Step 4: Configure Suricata ⚙️

Now, it’s time to configure Suricata to fit your network environment.

Set the Network Interface 🌐

Suricata needs to know which network interface to monitor. Open the configuration file and make the necessary adjustments.

sudo nano /etc/suricata/suricata.yaml

Inside the file, locate the af-packet section and set your network interface.

af-packet:
  - interface: eth0
    threads: auto
    defrag: yes
    cluster-type: cluster_flow
    cluster-id: 99
    copy-mode: ips
    checksum-checks: auto

Configure Logging 📝

Proper logging ensures you have the data needed for analysis. Here’s an example configuration:

default-log-dir: /var/log/suricata/

outputs:
  - eve-log:
      enabled: yes
      filetype: regular
      filename: eve.json
      types:
        - alert:
        - http:
        - dns:
        - tls:
        - ssh:
        - flow:

Step 5: Download and Update Suricata Rules 📄

Suricata uses rules to detect potential threats. Keeping these rules up to date is crucial.

Install suricata-update:

sudo apt install python3-pip 
sudo pip3 install --pre --upgrade suricata-update

Update Rules:Download the latest rule sets.

sudo suricata-update

Verify the Rule Configuration:Ensure the rules are configured correctly.

sudo suricata -T -c /etc/suricata/suricata.yaml

Step 6: Start Suricata 🚀

Now that Suricata is configured, it’s time to start it up!

IDS Mode (monitoring only):

sudo suricata -c /etc/suricata/suricata.yaml -i eth0
  • IPS Mode (monitoring and blocking):
sudo suricata -c /etc/suricata/suricata.yaml --af-packet=eth0

Step 7: Test the Installation 🧪

Test Suricata by generating some network traffic. Use nmap or another tool to initiate traffic that should trigger alerts.

nmap -sS -Pn -p 80,443 <target-ip>

Check the logs:

tail -f /var/log/suricata/eve.json

You should see alerts matching the traffic.

Step 8: Automate Suricata Startup 🔧

To ensure Suricata starts automatically when your system boots, enable it as a service.

sudo systemctl enable suricata
sudo systemctl start suricata
