Silverfort Universal MFA

Overview

Silverfort Universal MFA is an identity security solution that provides Multi-Factor Authentication (MFA) for Windows Logon, RDP, VPN access, and other resources across on-premises environments, without requiring changes to applications or infrastructure.

  • Vendor: Silverfort
  • Supported environment: On Premise
  • Detection based on: Telemetry
  • Supported application or feature: Authentication Logs, DailyAuthStatistics

Specification

Prerequisites

  • Resource:
    • Self-managed syslog forwarder
  • Network:
    • Outbound traffic allowed
  • Permissions:
    • Admin access to Silverfort Universal MFA Console
    • Root access to the Linux server with the syslog forwarder

Transport Protocol/Method

  • Indirect Syslog

Logs details

  • Supported functionalities: See section Overview
  • Supported type(s) of structure: CEF (Common Event Format)
  • Supported verbosity level: Informational

Note

Log levels are based on the taxonomy of RFC5424. Adapt according to the terminology used by the editor.

Step-by-Step Configuration Procedure

Instructions on the 3rd Party Solution

This setup guide will show you how to forward your Silverfort Universal MFA logs to Sekoia.io by means of a syslog transport channel.

Configure Syslog Forwarding

  1. Log into the Silverfort Universal MFA console and navigate to:

    SYSTEM SETTINGS > Notifications > Syslog

  2. Add a new Syslog Server and configure the following fields:

    • Server Name: Enter a descriptive name for the syslog destination.
    • Host: Enter the IP address or hostname of your syslog forwarder.
    • Protocol: Select TCP (recommended).

  3. Save the configuration.

Instruction on Sekoia

Configure Your Intake

This section will guide you through creating the intake object in Sekoia, which provides a unique identifier called the "Intake key." The Intake key is essential for later configuration, as it references the Community, Entity, and Parser (Intake Format) used when receiving raw events on Sekoia.

  1. Go to the Sekoia Intake page.
  2. Click on the + New Intake button at the top right of the page.
  3. Search for your Intake by the product name in the search bar.
  4. Give it a Name and associate it with an Entity (and a Community if using multi-tenant mode).
  5. Click on Create.

Note

For more details on how to use the Intake page and to find the Intake key you just created, refer to this documentation.

Configure a forwarder

To forward events using syslog to Sekoia.io, you need to update the syslog header with the intake key you previously created. Here is an example of your message before the forwarder 

<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG RAW_MESSAGE
and after 
<%pri%>1 %timestamp:::date-rfc3339% %hostname% %app-name% %procid% LOG [SEKOIA@53288 intake_key=\"YOUR_INTAKE_KEY\"] RAW_MESSAGE

To achieve this you can:

  • Use the Sekoia.io forwarder which is the official supported way to collect data using the syslog protocol in Sekoia.io. In charge of centralizing data coming from many equipments/sources and forwarding them to Sekoia.io with the apporpriated format, it is a prepackaged option. You only have to provide your intake key as parameter.
  • Use your own Syslog service instance. Maybe you already have an intance of one of these components on your side and want to reuse it in order to centralize data before forwarding them to Sekoia.io. When using this mode, you have to configure and maintain your component in order to respect the expected Sekoia.io format.

Warning

Only the Sekoia.io forwarder is officially supported. Other options are documented for reference purposes but do not have official support.

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.

Detection section

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.

Event Categories

The following table lists the data source offered by this integration.

Data Source Description
Authentication logs Provides authentication request logs for Windows Logon, RDP and VPN
Third-party application logs Provides MFA request and response events
Application logs Daily authentication counts per Silverfort server

In details, the following table denotes the type of events produced by this integration.

Name Values
Kind event, metric
Category authentication
Type allowed, denied, info

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.
