Sumo Logic App for AWS Threat Intel

The Threat Intel for AWS App correlates CrowdStrike threat intelligence data with your AWS log data, allowing for real-time security analytics to help detect threats in your environment and protect against cyber-attacks. The Threat Intel for AWS App scans your AWS CloudTrail, AWS ELB and AWS VPC Flow logs for threats based on IP address.

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professions accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Collect Logs for the Threat Intel for AWS App

The Threat Intel for AWS App utilizes AWS logs and VPC Flow Logs.

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professional accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Configure Collectors and Sources

If you are not already collecting your AWS logs, follow the instructions below to collect data from one or more of these data sources:

• Collect AWS CloudTrail Logs
• Collect AWS ELB Logs

VPC Flow Logs can be published to Amazon CloudWatch Logs and Amazon S3. Each method has advantages. Using an AWS S3 source is more reliable, while using a CloudFormation template allows you to customize your logs by adding more information and filtering unwanted data. You can use either of the following methods to collect Amazon VPC Flow Logs:

• Using an AWS S3 source
• Using a CloudFormation template

Installing the Threat Intel for AWS App

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professions accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Now that you have set up collection, install the Sumo Logic App for Threat Intel for AWS to use the preconfigured searches and Dashboards that provide insight into your data.

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.
