Whether you’re fine-tuning an existing setup or embarking on a new security initiative, our goal is to equip you with knowledge and confidence.

Understanding Dynamic Blocklists

1.1 Introduction to Dynamic Blocklists

Dynamic blocklists, also known as threat feeds or real-time blocklists, are continuously updated lists of IP addresses, URLs, or domains associated with malicious activities. Unlike static blocklists, which require manual updates, dynamic blocklists are automated, providing a real-time response to emerging threats. They play a critical role in fortifying network defenses by preemptively blocking communications with known harmful entities.

1.2 How Dynamic Blocklists Function

Dynamic blocklists operate by pulling data from various threat intelligence sources, aggregating and analyzing it to identify malicious actors. These sources could include cybersecurity research organizations, threat intelligence sharing platforms, and other trusted entities that track and report on cyber threats.

Upon identification of a malicious IP address or domain, the dynamic blocklist is updated, and any attempt to communicate with these known threats is automatically blocked by the network’s firewall or security appliance. This process is ongoing, ensuring that the blocklist is always current and providing up-to-the-minute protection.

1.3 The Importance in Network Security

Implementing dynamic blocklists is paramount in today’s cybersecurity landscape for several reasons:

  • Proactive Defense: They provide a proactive approach to security, allowing organizations to block threats before they reach the network.
  • Resource Efficiency: Automating the threat blocking process saves valuable time and resources that would otherwise be spent on manual threat hunting and updating static blocklists.
  • Adaptability: The dynamic nature of these blocklists means they adapt quickly to the ever-changing threat landscape, maintaining a high level of security.

1.4 Examples of Threat Feeds and Blocklist Services

There are numerous threat feeds and IP blocklist services available, catering to different security needs and industries. Some well-known examples include:

  • Lupovis Prowl: A global threat intelligence feed providing data on known threats.
  • Spamhaus: Renowned for its blocklists aimed at preventing spam and related cyber threats.
  • DuggyTuxy: Provides a list of IP addresses and networks observed to be involved in malicious activities.

By integrating these services with FortiGate’s firewall, organizations can enhance their network security, ensuring a robust defense against malicious actors and potential cyber threats.

1.5 Obtaining the Lupovis Dynamic Blocklist

Lupovis provides uparalleled blocklists catering to a variety of specific security needs ranging from sectorial and geographical blocklists that are meticulously compiled to identify 0-day adversaries, human actors, bots, mass scanners, and a plethora of other potential threats to global blocklists.

This is made possible through an extensive network of sensors strategically placed across the internet, dedicated to analyzing and interpreting the incessant noise of online activity.

These sensors work tirelessly, classifying and categorizing the internet’s cacophony in real-time, ensuring that Lupovis’ blocklists are consistently accurate, reliable, and up-to-date.

As a result, organizations can trust in the efficacy of these blocklists to provide a robust layer of security, defending their networks against a wide array of cyber threats. With Lupovis, users are not just accessing blocklists; they are leveraging a comprehensive threat intelligence system that stands at the forefront of internet security.

Configuring Dynamic Blocklists in FortiGate

Achieving a more secure network environment is pivotal, and integrating dynamic blocklists into your FortiGate firewall is a crucial step in this journey. This section provides a detailed guide on how to configure dynamic blocklists within the FortiGate environment.

2.1 Accessing the FortiGate Web Interface

  1. Open Your Browser: Launch your preferred web browser.
  2. Enter the FortiGate IP Address/Hostname: Type in the IP address or hostname of your FortiGate device into the address bar, followed by :443 to specify the port (e.g.,
  3. Log in: Enter your username and password when prompted to access the FortiGate dashboard.

2.2 Setting Up Security Fabric

  1. Navigate to Security Fabric: In the left-hand menu, click on “Security Fabric”.
  2. Configure Security Fabric: Ensure that Security Fabric is enabled and properly configured to include all relevant devices in your network.

2.3 Configuring an External Connector

  1. Go to External Connectors: Within the “Security Fabric” settings, find and select “External Connectors”.

  1. Add a New Connector: Click “IP Addresses” or “Add” to setup a new external connector.
  2. Configure the Threat Feed:
    • Name: Give the connector a descriptive name.
    • Feed URL: Enter the URL of the dynamic blocklist/threat feed.
    • Update Interval: Set how frequently FortiGate should pull updates from the threat feed.
    • Test Connection: Ensure that FortiGate can successfully retrieve data from the threat feed URL.

  • Apply the External Connector:
    • In the policy settings, locate the section for source or destination addresses.
    • Add the external connector you’ve configured to the policy, in our case. Lupovis_Blocklist
  • Configure the rules to match incoming traffic
    • Right click and Edit CLI

Type in Set match-vip enable

The set match-vip command in FortiGate’s firewall policy configuration is used to control how the firewall handles traffic in relation to Virtual IPs (VIPs) configured on the device.

When you configure a VIP on a FortiGate device, you are essentially setting up a rule to forward traffic from one IP address to another, usually from a public IP address to a private IP address behind the firewall. This is often used for services such as web hosting, where you need to make an internal resource available externally.

2.5 Verifying and Monitoring

  1. Monitor Traffic: Use the “Log & Report” section to monitor network traffic and ensure that the dynamic blocklist is actively being enforced.
  2. Regularly check that the IP are being updated
