Trellix Network Security

Overview

Trellix Network Security is an effective cyberthreat protection solution that helps your organization minimize the risk of costly breaches by accurately detecting and immediately stopping advanced, targeted, and other evasive attacks hiding in internet traffic.

  • Vendor: Trellix
  • Plan: Defend Core & Defend Prime
  • Supported environment: On prem
  • Version compatibility: 10.0.1
  • Detection based on: Telemetry
  • Supported application or feature: Web logs

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

  1. Log onto the Trellix NX console
  2. Go to Settings > Notifications
  3. Click on rsyslog and check the Event type check box below
  4. In the Settings panel, select the Default format as CEF
  5. In the Rsyslog Server Listing, type a name for the new entry then click on the button Add Rsyslog Server
  6. For the new server, check the Enabled checkbox, type the ip address of your syslog concentrator
  7. Click on the Update button to validate the configuration
  8. (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.

The following section provides information for those who wish to learn more about the detection capabilities enabled by collecting this intake. It includes details about the built-in rule catalog, event categories, and ECS fields extracted from raw events. This is essential for users aiming to create custom detection rules, perform hunting activities, or pivot in the events page.

The following Sekoia.io built-in rules match the intake Trellix Network Security. 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.

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.

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 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.

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.
