Configure
This setup guide will show you how to forward your Trellix Network Security logs to Sekoia.io by means of a syslog transport channel.
Prerequisites
You should have:
- Have an admin access in Trellix platform.
- Have an internal log concentrator (Rsyslog)
Enable Syslog forwarding for Trellix Network Security
- Log onto the Trellix NX console
- Go to
Settings > Notifications
- Click on
rsyslog
and check theEvent type
check box below - In the Settings panel, select the
Default format
asCEF
- In the
Rsyslog Server Listing
, type a name for the new entry then click on the buttonAdd Rsyslog Server
- For the new server, check the
Enabled
checkbox, type the ip address of your syslog concentrator - Click on the
Update
button to validate the configuration - (Optional) Click on the
Test-fire
button if you want to test the forwarding of the logs
Create the intake
Go to the intake page and create a new intake from the format Trellix Network Security.
Configure the Rsyslog server
Please consult the Rsyslog Transport 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.

CVE-2020-0688 Microsoft Exchange Server Exploit
Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page. The vulnerability is due to Microsoft Exchange Server not randomizing the keys on a per-installation basis resulting in them using the same validationKey and decryptionKey values. With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

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.

TOR Usage
Detects TOR usage, based on the IP address and the destination port (filtered on NTP). TOR is short for The Onion Router, and it gets its name from how it works. 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.

Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works.

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.
