AD FS Log Tools

AdfsEventsModule Overview

This module provides tools for gathering related ADFS events from the security, admin, and debug logs, across multiple servers. This tool also allows the user to reconstruct the HTTP request/response headers from the logs.

Cmdlets in AdfsEventsModule

This module exposes the following cmdlets:

Get-ADFSEvents - Allows you to query servers for ADFS logs. Contains options for querying, aggregation, and analysis
Write-ADFSEventsSummary - Allows you to generate a summary of an ADFS request, based on the logs from Get-ADFSEvents
Enable-ADFSAuditing - Enables all the ADFS and OS auditing switches on the current server, and enables just the ADFS switches on remote servers
Disable-ADFSAuditing - Disables all the ADFS and OS auditing switches on the current server, and disables just the ADFS switches on remote servers

The detailed parameters for Get-ADFSEvents and Write-ADFSEventsSummary are provided below.

The Get-ADFSEvents cmdlet is used to aggregate events by correlation ID, while the Write-ADFSEventsSummary cmdlet is used to generate a PowerShell Table of only the most relevant logging information from the events that are piped in.

Get-ADFSEvents Parameters

Logs - A list of AD FS logs to include in the aggregation. Current options are: "Admin", "Debug", "Security". The default will pull from both Security and Admin.
CorrelationID - The correlation ID for a single request. This will aggregate all chosen logs for this request
All - This flag will cause all events in the desired logs to be grouped by correlation ID.
CreateAnalysisData - This flag can be combined with any means of event collection (a single Correlation ID, all events, or time based) to reconstruct the HTTP requests that were performed for each Correlation ID.
StartTime - The UTC start time to use when aggregating multiple requests. All requests that start after this time will be aggregated
EndTime - The UTC end time to use when aggregating multiple requests. All requests that end before this time will be aggregated
Server - A comma-separated list of server names to pull logs from. On ADFS 2016 and up, you can use "*" to query all The default will query LocalHost

Get-ADFSEvents Output

The output produced by Get-ADFSEvents is a list of objects, each containing the following properties.

CorrelationID - the Correlation ID for this set of events
Events - a list of EventLogRecord objects for the matching Correlation ID.
AnalysisData - a JSON data blob containing details on the HTTP requests that were performed during the course of this transaction For more details on the AnalysisData blob, see below

Using Get-ADFSEvents

Import the PowerShell Module

In a PowerShell window, run the following:

ipmo AdfsEventsModule.psm1
Run Get-ADFSEvents with your desired parameters to get a list of PowerShell objects

EXAMPLE: Retrieve all logs from two servers for a specific request

$logs = Get-ADFSEvents -Logs Security, Admin, Debug -CorrelationID 0c0fd6ee-4b1e-4260-0300-0080070000e3 -Server LocalHost, MyServer

OUTPUT:
```
Events                              AnalysisData  CorrelationID
------                              -------       -------------

{EventLogRecord, EventLogRecord}    {}            0c0fd6ee-4b1e-4260-0300-0080070000e3
```

To view specific records:

$logs[0].Events[0]

OUTPUT:

Message         : An HTTP request was received. See audit 510 with the same Instance ID for headers.

You can output the full data objects from Get-ADFSEvents to XML using:

Export-Clixml

Import-Clixml

The AnalysisData Blob

The AnalysisData blob contains the following:

requests - a set of HTTP requests made during the current transaction. Each request contains request details, HTTP header information, and session token information (when available)
responses - a set of HTTP responses given during the current transaction. Each response contains response details, HTTP header information, and outgoing tokens (when available)
errors - a set of EventLogRecord objects from the current transaction that are marked as errors
timeline - a set of timeline events to show the progress of a transaction through the ADFS pipeline. Timeline events correspond to roughly the following:
- incoming - ADFS received an incoming HTTP request
- authn - ADFS is performing authentication
- authz - ADFS is performing authorization checks
- issuance - ADFS is performing token issuance
Each timeline event contains a success or failure result, indicating whether the given pipeline step was a success or failure.

Pester Tests

This project includes a set of Pester tests to ensure the basic functionality of the script.

To run the tests, you must have Pester version 4.x or higher installed on the machine you will run Get-ADFSEvents from. For more information on installing Pester, see their installation instructions.

Once Pester is installed, you can copy the test file and script to the same location, and run the following:

cd <directory containing tests and script>
Invoke-Pester -Script .\Test.AdfsEventsModule.ps1

For more details, see the testing Readme
