Collect Events from Vendor

​

• Broker VM - Windows Event Collector (Recommended)
• XDRC (XDR Collector)
  ​
  ​

Broker VM (Windows Event Collector)

To create or configure the Broker VM, use the information described here.

To connect and use Windows Event Collector, use the information described here.

When configuring the Windows Event Collector (WEC), use the following settings in the Configurations > Broker VMs > WEC > Collection Configuration section:

• Source: “FederationServices Deployment”
• Min. Event Level: “Verbose”

• Event IDs Group: “All”

  • Pay attention: Timestamp parsing support is under the assumption that a UTC +0000 format is being used.

XDRC (XDR Collector)

​
To create or configure the Winlogbeat collector, use the information described here.

As Cortex XSIAM provides a YAML template for Microsoft AD FS Event Logs, you can use the following steps to create a collection profile:

1. In Cortex XSIAM, select Settings → Configurations → XDR Collectors → Profiles → +Add Profile → Windows.
2. Select Winlogbeat, then click Next.
3. Configure the General Information parameters:

• Profile Name — Specify a unique Profile Name to identify the profile. The name can contain only letters, numbers, or spaces, and must be no more than 30 characters. The name you choose will be visible from the list of profiles when you configure a policy.

• Add description here — (Optional) Provide additional context for the purpose or business reason that explains why you are creating the profile.

1. Configure the settings for the profile selected in Step 2. To add the “Microsoft AD FS” template, select it and click Add.

Note: The AD FS XDR Collector supports AD FS and ADFS Auditing logs (provider_name).
