Installing the Amazon GuardDuty Cloud Security Monitoring and Analytics App

Now that you have set up the collection for Amazon GuardDuty, install the Sumo Logic App to use the pre-configured searches and dashboards that provide visibility into your environment for real-time analysis of overall usage.

To install the app, do the following:

Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.

1. From the App Catalog, search for and select the app.
2. Select the version of the service you're using and click Add to Library. Version selection is applicable only to a few apps currently. For more information, see the Install the Apps from the Library.
3. To install the app, complete the following fields.
   1. App Name. You can retain the existing name, or enter a name of your choice for the app.

   2. Data Source. Select either of these options for the data source.

      • Choose Source Category, and select a source category from the list.

      • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (_sourceCategory=MyCategory).

   3. Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
4. Click Add to Library.

Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization.

Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps.

Trending All Findings. Line chart showing the relative volumes of findings over the last 24 hours by default or the dashboard time window setting separated by severity.

Last 20 Findings. Provides a table detailing the most recent findings.

High, Medium, Low Severity Findings

Note all panels for High, Medium, and Low Severity findings are the same. The only difference is filtering based on the listed severity level.

Severity Findings Last Hour. See the count of findings at this severity in the last hour with a sparkline showing the trending of the last 24 hours by default or the dashboard time window setting.

Severity Outliers. Review the trending volume of findings at this severity level over the last 24 hours by default or the dashboard time window setting. The gray thresholds show ranges within 4 standard deviations of the past 5 mean values. Pink triangles show values that exceed that threshold and are likely points of investigation considering the large change in volume of findings.
