How to install suricata-update on windows 10?

2

Here’s a step-by-step guide to installing and using suricata-update on Windows 10:

Prerequisites:

  1. Install Suricata: First, you need to have Suricata installed on your Windows system. You can download the latest version from the Suricata website. For this example, let’s assume you’ve installed Suricata version 7.0.8 or later, which includes suricata-update.

  2. Npcap or WinPcap: Suricata requires a packet capture library. Install Npcap since it’s the recommended modern equivalent of WinPcap.

Steps to Install and Use suricata-update:

Step 1: Install Suricata

  • Download the Windows installer for Suricata from the official site.

  • Run the installer and follow the prompts to install Suricata. Make sure to add the Suricata installation directory to your system PATH for ease of use from the command line.

Step 2: Install Npcap

  • Download Npcap from the official Nmap website.

  • Install Npcap, selecting “WinPcap API-compatible mode” during installation for compatibility with Suricata.

Step 3: Update Suricata Rules with suricata-update

suricata-update should be included with your Suricata installation. Here’s how you can use it:

  • Open Command Prompt or PowerShell with administrative privileges.

  • Navigate to the directory where Suricata is installed or where you can execute Suricata commands from the PATH:


cd C:\Program Files\Suricata
  • Run suricata-update to download and update the rules:

suricata-update

This command will fetch the latest rules from the default source (usually Emerging Threats Open ruleset). Here’s an example of what the output might look like:


2025-01-04 10:15:00,347 - <Info> - Updating rule set from ET Open

2025-01-04 10:15:02,456 - <Info> - Downloading rule index

2025-01-04 10:15:04,567 - <Info> - Downloading rules

2025-01-04 10:15:09,123 - <Info> - Writing rules to file(s)

2025-01-04 10:15:09,234 - <Info> - Done
  • By default, suricata-update writes the rules to C:\ProgramData\Suricata\rules\ or similar, depending on your installation.

Step 4: Configure Suricata to Use Updated Rules

  • Edit your suricata.yaml configuration file (usually found in C:\Program Files\Suricata\ or wherever you installed Suricata):

  • Ensure that the default-rule-path and rule-files settings point to where suricata-update saved the rules. For example:


default-rule-path: C:\ProgramData\Suricata\rules

rule-files:

- suricata.rules
  • Save the changes to suricata.yaml.

Step 5: Run Suricata

  • Start Suricata with the updated rules:

suricata -c suricata.yaml -i <interface_name>

Replace <interface_name> with your network interface name, which can be found using ipconfig in the command prompt.
