Tenable Identity Exposure / Alsid

Overview

Tenable Identity Exposure / Alsid is an automated security solution that monitors the components of Active Directory infrastructures by detecting attacks in real time, identifying existing weaknesses and vulnerabilities.

Vendor: Tenable Identity Exposure / Alsid
Supported environment: On prem
Detection based on: Alert, Telemetry
Supported application or feature:Application logs, Authentication logs, Network protocol analysis

Configure

As of now, the main solution to collect Tenable Identity Exposure / Alsid logs leverages the Rsyslog recipe. Please share your experiences with other recipes by editing this documentation.

Rsyslog

Please refer to the documentation of Tenable Identity Exposure / Alsid to forward events to your rsyslog server. The reader is also invited to consult the Rsyslog Transport documentation to forward these logs to Sekoia.io.

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.

The following Sekoia.io built-in rules match the intake Tenable Identity Exposure / Alsid. 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.

Event Categories

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

Data Source	Description
`Application logs`	Alsid events bring information from Active Directory logs
`Authentication logs`	Alsid alerts provide details on anomalies/threats detected in authentication logs
`Network protocol analysis`	information on LDAP, DNS and Kerberos protocols are collected through Alsid logs

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

Name	Values
Kind	`alert`, `trailflow`
Category	``

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.
