SonicWall Firewall
Overview
SonicWall firewalls enable you to identify and control all applications that are running on your network. By identifying applications based on their unique signatures rather than ports or protocols, this additional control improves compliance and data leakage prevention.
- Vendor: SonicWall
- Supported environment: On prem
- Version compatibility: 7,0,1
- Detection based on: Telemetry
- Supported application or feature: DNS records, Host network interface, Network device logs, Network intrusion detection system, Network protocol, Web logs analysis
Configure
This setup guide will show you how to forward your SonicWall logs to Sekoia.io by means of a syslog transport channel.
Prerequisites
- Must have GMS server or On-Prem Analytics server installed and configured.
- Have an Address Object Created on the Firewall for SonicWall Analytics system.
- Have an internal log concentrator (Rsyslog)
Enable Syslog forwarding for SonicWall 6.5 and 7.X
Info
Only the Syslog format ArcSight
is supported by this integration.
Log on your SonicWall appliance and follow this guide to enable syslog forwarding, except for the step 4 : Select Syslog Format as 'Enhanced', you must select Syslog format 'ArcSight' instead.
Create the intake
Go to the intake page and create a new intake from the format SonicWall Firewall.
Forward logs to Sekoia.io
Please consult the Syslog Forwarding documentation to forward these logs to Sekoia.io.
Raw Events Samples
In this section, you will find examples of raw logs as generated natively by the source. These examples are provided to help integrators understand the data format before ingestion into Sekoia.io. It is crucial for setting up the correct parsing stages and ensuring that all relevant information is captured.

Suspicious TOR Gateway
Detects suspicious TOR gateways. Gateways are often used by the victim to pay and decrypt the encrypted files without installing TOR. Tor intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult.

Detects wceaux.dll creation while Windows Credentials Editor (WCE) is executed.
- Effort: intermediate
WMI Persistence Script Event Consumer File Write
Detects file writes through WMI script event consumer.
- Effort: advanced
Webshell Creation
Detects possible webshell file creation. It requires File Creation monitoring, which can be done using Sysmon's Event ID 11. However the recommended SwiftOnSecurity configuration does not fully cover the needs for this rule, it needs to be updated with the proper file names extensions.
- Effort: master
ZIP LNK Infection Chain
Detection of an ZIP download followed by a child-process of explorer, followed by multiple Windows processes.This is widely used as an infection chain mechanism.

Transformed Events Samples after Ingestion
This section demonstrates how the raw logs will be transformed by our parsers. It shows the extracted fields that will be available for use in the built-in detection rules and hunting activities in the events page. Understanding these transformations is essential for analysts to create effective detection mechanisms with custom detection rules and to leverage the full potential of the collected data.
