WatchGuard Firebox

Overview

WatchGuard Firebox is a serie of high-performance firewalls to protect computer networks. Sending WatchGuard Firebox logs to Sekoia.io enables the discovering of potential network security threats. Spotted threats are contextualized by means of Sekoia.io's Cyber Threat Intelligence (CTI).

The following Sekoia.io built-in rules match the intake WatchGuard Firebox. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

SEKOIA.IO x WatchGuard Firebox on ATT&CK Navigator

Bazar Loader DGA (Domain Generation Algorithm)

Detects Bazar Loader domains based on the Bazar Loader DGA

  • Effort: elementary
Burp Suite Tool Detected

Burp Suite is a cybersecurity tool. When used as a proxy service, its purpose is to intercept packets and modify them to send them to the server. Burp Collaborator is a network service that Burp Suite uses to help discover many kinds of vulnerabilities (vulnerabilities scanner)

  • Effort: intermediate
Potential Azure AD Phishing Page (Adversary-in-the-Middle)

Detects an HTTP request to an URL typical of the Azure AD authentication flow, but towards a domain that is not one the legitimate Microsoft domains used for Azure AD authentication.

  • Effort: intermediate
Potential DNS Tunnel

Detects domain name which is longer than 95 characters. Long domain names are distinctive of DNS tunnels.

  • Effort: advanced
SEKOIA.IO Intelligence Feed

Detect threats based on indicators of compromise (IOCs) collected by SEKOIA's Threat and Detection Research team.

  • Effort: elementary
Telegram Bot API Request

Detects suspicious DNS queries to api.telegram.org used by Telegram Bots of any kind

  • Effort: advanced

Configure

Prerequisites

An internal log concentrator (Rsyslog) is required to collect and forward events to Sekoia.io.

Enable Syslog forwarding

Log on your Firebox appliance and follow this guide to enable syslog forwarding.

Configure the event forwarding to use the IBM LEEF format (for more information, please read the associated documentation).

Create the intake

Go to the intake page and create a new intake from the format WatchGuard Firebox.

Forward logs to Sekoia.io

Please consult the Rsyslog Transport documentation or Syslog Forwarding documentation to forward these logs to Sekoia.io.
