PCI Compliance for Windows JSON

This guide helps you set up Sumo Logic Collectors, and install the PCI Compliance for Windows JSON application, so you can begin monitoring your usage and determine if you are meeting Compliance benchmarks.

Log types

The PCI Compliance For Windows JSON App uses Windows Security Event and System Event logs. It does not work with third-party logs.

Collecting logs for the PCI Compliance for Windows JSON app

This section provides instructions for configuring log collection for the PCI Compliance for Windows JSON App.

Configure a Collector and a Source

To configure a collector and source, do the following:

1. Configure an Installed Windows collector through the user interface or from the command line.
2. Configure either a local or remote Windows Event Log source. To configure a Windows Event Log source set the following:
   • Event Format. Select Collect using JSON format. Events are formatted into JSON that is designed to work with Sumo Logic features, making it easier for you to reference your data.
   • Event Collection Level. When JSON format is selected you have to select Complete Message from the dropdown. Complete Message will ingest the entire event content along with metadata.

For more information on local or remote Windows Event Log Source configuration, refer to Local Windows Event Log Source and Remote Windows Event Log Source.

Make sure to set the Source Category when configuring the Windows Event Log source. For example: OS/Windows/Events.

Installing the PCI Compliance for Windows JSON app

To install the app, do the following:

1. From the Sumo Logic navigation, select App Catalog.
2. In the Search Apps field, search for and then select your app.
   Optionally, you can scroll down to preview the dashboards included with the app.
3. To install the app, click Install App.
4. Click Next in the Setup Data section.
5. In the Configure section of the respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category, and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Your app will be installed in the Installed Apps folder and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, updating with full graphs and charts over time.

Viewing PCI Compliance for Windows JSON dashboards

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filter with template variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
